We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a ...

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 ...

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.

Motion engineers can spend hours optimizing tuning parameters in servo-based systems, and still not get the performance they want. Motion engineers can spend hours optimizing tuning parameters in ...

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 ...

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 ...

Cams convert ordinary shaft rotation into a more complicated pattern of motion. Learn about the two subtypes. Cams convert ordinary shaft rotation into a more complicated pattern of motion. This is ...

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 ...
