1.
Acceleration, rate at which velocity changes with time, in terms of both speed and direction.
2.
In classical mechanics, free fall is any motion of a body where gravity is the only force acting upon it. A freely falling object may not necessarily be falling down in the vertical direction.
3.
Momentum is a fundamental concept in physics that quantifies the motion possessed by an object. It is defined as the product of an object's mass and velocity. In other words, momentum is determined by multiplying the mass of an object by its velocity.
4.
Velocity, quantity that designates how fast and in what direction a point is moving.
5.
Gravity is the force of fundamental attraction between all things that have mass or energy..
6.
Any net force causing uniform circular motion is called a centripetal force.
7.
Speed refers to the rate at which an object changes its position, typically measured in units of distance per time, such as miles per hour (mph) or kilometers per hour (km/h).
