Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

This week Shini sits down with us to discuss centripetal force, centrifugal force, and a few other bits of physics to help us understand Uniform Circular motion. Crash Course Physics is available to ...

When an object changes velocity, it accelerates. Acceleration is the change in velocity per second and is measured in m/s 2. Acceleration is a vector quantity because it has size and direction. The ...

When a body or object moves in a circle, it is said to be in a circular motion. That is we can say that motion in a circle is a circular motion. When a body or object moves along a circular path, then ...

Isaac Newton's First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." What, then, happens to a body ...
