Forcefulness is a physics term that is defined equally an influence that causes an object to modify its rate or direction of movement or rotation. A forcefulness tin can accelerate objects by pulling or pushing them. The human relationship between force, mass, and acceleration was defined by Isaac Newton in his 2d law of motion, which states that an object's forcefulness is the product of its mass and acceleration. If yous want to know how to measure force, only follow these steps.

1. 1

   Sympathize the relationship betwixt force, mass, and dispatch. The forcefulness of an object is but the production of its mass and acceleration.^[1] This relationship tin can be divers past the following formula: Forcefulness = Mass ten Dispatch. Here are a few other things to keep in mind as y'all measure strength:

   • The standard unit for mass is kilograms (kg).
   • The standard unit for dispatch is thousand/south².
   • The standard unit for force is the newton (N). The newton is a derived standard unit. 1N = 1 kg ten 1m/s².

2. 2

   Measure the mass of a given object. An object's mass is the corporeality of thing that information technology contains.^[ii] The mass of an object never changes, no matter what planet information technology'southward on; while weight fluctuates depending on gravitational pull, your mass is the same on Globe and on the Moon.^[iii] In the metric system, mass can be expressed in grams or kilograms. Let's say the object we're working with is a truck that has a mass of 1000 kg.

   • To find the mass of a given object, identify it on a triple axle or a double pan residue. This volition calculate the mass in kilograms or grams.
   • In the English language arrangement, mass tin be expressed in pounds. Because force can as well be expressed in pounds, the term "pound-mass" has been coined to distinguish its usage. However, if you find the mass of an object using pounds in the English system, it's all-time to convert information technology to the metric system. If yous know an object's mass in pounds, simply multiply it by .45 to find the mass in kilograms.

   Measure the object's acceleration. In physics, acceleration is defined equally a change in velocity, which is divers every bit speed in a given direction, per unit of fourth dimension.^[4] In improver to the common definition of acceleration as speeding up, it also can hateful an object is slowing down or changing direction.^[v] Just as velocity can exist measured with a speedometer, acceleration is measured with an accelerometer. Let'southward say the dispatch of the 1000 kg truck we're working with is 3m/s².

   • In the metric system, velocity is expressed in centimeters per 2d or meters per 2nd, and dispatch is expressed every bit centimeters per second per 2nd (centimeters per second squared) or meters per second per second (meters per second squared).
   • In the English language system, 1 mode to express velocity is equally feet per second, so dispatch tin be expressed in feet per second squared.

4. four

   Multiply the object's mass by its dispatch. This is the force's value. Simply plug in the known numbers into the equation and you will know the force of the object. Remember to state your answer in newtons (Ns).^[vi]

   • Force = Mass 10 Dispatch
   • Strength = 1000 kg ten 3m/s²
   • Force = 3000N

1. 1

   Detect mass if you lot know forcefulness and dispatch. If you know the force and acceleration of an object, merely plug them into the same formula to find the object's mass. Hither'due south how to do it:^[7]

   • Force = Mass x Acceleration
   • 3N = Mass 10 3m/southward²
   • Mass = 3N/3m/south²
   • Mass = 1 kg

2. 2

   Observe acceleration if you know force and mass. If yous know the forcefulness and mass of an object, simply plug them into the same formula to find the object'southward mass. Hither's how to practise it:^[8]

   • Forcefulness = Mass x Acceleration
   • 10N = 2 kg x Acceleration
   • Dispatch = 10N/2kg
   • Acceleration = 5m/south²

3. 3

   Find the dispatch of an object. If you want to discover the force of an object, yous can calculate its acceleration equally long as you lot know its mass. All you have to practise is use the formula for finding the acceleration of an object. The formula is (Dispatch = Concluding Velocity - Initial Velocity)/Time.^[9]

   • Example: A runner reaches a speed of 6 m/s in 10 seconds. What is his acceleration?
   • The final velocity is six k/s. The original velocity is 0 thousand/s. The fourth dimension is 10s.
   • Acceleration = (6 m/s - 0 thou/southward)/10s = half dozen/10s = .6m/s^two

• Question

  Is it possible to measure the force of a stationary object?

  

  Yes. Yous tin can mensurate the forcefulness of gravity pulling the object. Simply use the gravitational constant for the acceleration of the object.

• Question

  What is mass movement?

  

  Mass motion is the movement of surface fabric caused by gravity. Landslides and rockfalls are examples of very sudden movements of this type. Geological agents such as water, wind and water ice all work with gravity to cause a leveling of land, too.

• Question

  What is a gravitational force?

  

  A force acquired past a massive object (as opposed to a massless object). There are various theories equally to how gravity works. Newton's is easiest to understand and utilize, but more up-to-engagement theories (such as general relativity) are used when increased accuracy is needed.

• Question

  What is the formula for kinetic energy?

  

  The bones formula for kinetic energy is mass 10 velocity squared, divided by 2.

• Question

  What is the divergence between weight and forcefulness?

  

  Weight is a particular type of forcefulness, acquired by a gravitational field interim upon a mass.

• Mass tin can too be expressed in slugs, with a slug equal to 32.174 pounds-mass. A slug is the amount of mass that one pound-force can accelerate at 1 pes per second squared. When multiplying a mass in slugs by acceleration in feet per second squared, the conversion constant isn't used.

• Thus, a mass of 640 pounds-mass accelerating at 5 anxiety per second squared carries an approximate force of 640 times 5 divided by 32 or 100 pounds-forcefulness.

• Separate the consequence by a conversion constant if yous're working with English units. As noted above, "pound" tin be either a unit of mass or strength in the English system; when used as a unit of strength, it is called "pound-force." The conversion constant is 32.174 pound-feet per pound force second-squared; 32.174 is the value of dispatch due to Earth's gravity in anxiety per 2nd squared. (To simplify the math here, we'll round to a value of 32.)

• Note that the human relationship betwixt force, mass and acceleration ways that an object with low mass and loftier acceleration tin have the same force as an object with high mass and low dispatch.

• A mass of 150 kilograms accelerating at 10 meters per second squared carries a force of 150 times 10, or 1500 kilogram-centimeters per second squared. (A kilogram meter per 2nd squared is called a newton.)

• Forces may take special names depending on how they act on an object. A force that causes an object to speed up is called thrust, while a force that causes an object to deadening downwardly is called drag. A strength that changes the way a rotating object spins around its axis is chosen torque.

• Weight is the expression of a mass existence acted on past the acceleration due to gravity.^[x] At Earth's surface, this dispatch is about 9.8 meters per 2d squared (ix.80665), or 32 anxiety per second squared (32.174). Thus, in the metric system, a 100 kilogram mass weighs about 980 newtons, and a 100 gram mass weighs well-nigh 980 dynes. In the English system, mass and weight tin be expressed in the same units, so 100 pounds of mass (or pounds-mass) weighs 100 pounds (pounds-force). Because a jump calibration measures the pull of gravity on an object, it actually measures weight, not mass. (In common usage, there is no distinction, and so long as the only gravity under consideration is that of Earth's surface.)

• A mass of twenty grams accelerating at v centimeters (2.0 in) per 2nd squared carries a forcefulness of 20 times 5, or 100, gram-centimeters per second squared. (A gram centimeter per second squared is called a dyne.)

About This Article

Article Summary Ten

To measure force, expect at the formula strength equals mass times dispatch (F=M*A). An object'due south mass is the amount of matter that it contains and is expressed in grams or kilograms. Dispatch is the change in velocity, which is speed in a given management, per unit of time. Acceleration is expressed every bit centimeters per second per second, which is centimeters per 2d squared. Multiply the object's mass by its acceleration to find the strength's value, and state your reply in newtons (Ns). If you want to learn how to find the dispatch or mass if yous know the strength of an object, keep reading the commodity!
