Q- Describe the direction, speed, and acceleration of an object moving with uniform circular motion.
A- An object moving in a circle still wants to move in a straight line. This straight-line motion is always at a tangent to the circle, so the speed of an object moving in a circle is known as tangential speed. In uniform circular motion, the speed remains constant while the direction of the object changes. This means the object experiences an acceleration toward the center of the circle, which is known as centripetal acceleration.
