Centripetal Acceleration in Circular Motion

Uniform circular motion describes motion in a circle at constant speed. An object follows a curved path, but its speed does not change. The motion of a point on a propeller spinning at a steady rate and the second, minute, and hour hands of a watch are common examples.

Even with constant speed, t...

An object moving along a circular path is said to exhibit circular motion, which can be either uniform or non-uniform. In uniform circular motion, the object moves at a constant speed.

For an orbiting satellite, the Earth's gravitational force provides the centripetal force required for circular motion.

At any instant, the linear v...
