Acceleration : An object’s acceleration is the rate at which its velocity changes. It can either be positive (speeding up) or negative (slowing down). The speed is usually measured in meters per second squared (m/s^2).

Time : The duration between two events is called time. Minutes (min) and hours (h) are usually used for measuring time.

Distance : Distance is the distance between two points. A meter (m), kilometer (km), or centimeter (cm) is usually used to measure it.

Displacement : The displacement of an object is the change in its position in a particular direction. Usually, it is measured in meters (m) or kilometers (km).

Uniform Motion: The definition of uniform motion is when an object travels at a constant speed in a straight line.

Non-Uniform Motion – In non-uniform motion, an object travels at varying speeds in a straight line or in a curved path.
