In mechanics, for a body with constant mass, the acceleration of the body is proportional to the net force acting on it.
where F is the resultant force acting on the body, m is the mas of the body, and a is its acceleration.
Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
When an object's velocity changes, it accelerates. Acceleration shows the change in velocity in a unit time. Velocity is measured in meters per second, m/s, so acceleration is measured in (m/s)/s, or m/s2, which can be both positive and negative.
