KEYWORDS
Force is what causes mass to accelerate or become deformed.
Acceleration is the rate at which the velocity of a body changes with time
In kinematics, Velocity is the speed of an object and a specification of its direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving.
Mass is a quantitative measure of an object's resistance to acceleration
