Q

Law of acceleration

A

the acceleration of an object depends on its mass and the force acting upon it. The greater the force the greater the acceleration. The more massive the object, the more force it takes to accelerate it. Additionally, if a constant force acts upon an object, the object will move with constant acceleration in the direction of the force.
