How does force affect speed?

The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it can be said that a force on an object results in the acceleration of an object.

How force and velocity are related?

So force is the change in (mass times velocity) with respect to time: F = d(mv)/dt. In most situations we figure mass is constant. So force is proportional to a change in velocity. (F = m dv/dt, or mass times acceleration.)

What force changes the velocity of an object?

A change in speed is a change in velocity – so, a change in speed is an example of acceleration! Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. When a force acts on an object; it may change the object's acceleration (speed, direction, or both).
