Average Force Formula
The following formula is used to calculate the average force of a moving object.
F = m * (Vf - Vi) / t
- Where F is the average force (N)
- m is the mass (kg)
- Vf is the final velocity (m/s)
- Vi is the initial velocity (m/s)
- t is the change in time
To calculate average force, multiply the mass by the difference in velocity, then divide by time.
Average Force Definition
Force is an interaction that causes a change in motion of an object. In other words, a force applied to an object causes that object to change in velocity. Note that this is a change in velocity, not just a change in position. Objects can change position when under a constant velocity but with no force.
The average force more specifically is the average amount of force that would have been applied to a certain object to increase its speed from an initial to final velocity over a given time. In reality, the force may have been variable, but the result would be the same with the calculated average force.
Average Force Example
How to calculate average force?
- First, determine the mass.
For this example the object is measured at 10kg.
- Next, determine the initial velocity.
In this example, the object is at rest initially, so the velocity is 0m/s.
- Next, determine the final velocity.
The final velocity is 20m/s.
- Next, determine the change in time.
It took 5 seconds to increase the speed to 20m/s.
- Finally, calculate the average force.
The average force is calculated to be 10 * (20-0) / 5 = 40.
FAQ
An average force is the average amount of force over a certain amount of time that is required to move an object from an initial velocity to a final velocity.
