Question
Which of the following is an example of uniform circular motion?*1 pointA . A car turning around a cornerB . A cyclist pedaling uphillC . A satellite orbiting the EarthD . A ball bouncing on the ground
Solution
The example of uniform circular motion from the options provided is C. A satellite orbiting the Earth.
Here's why:
Uniform circular motion refers to the motion of an object traveling at a constant speed on a circular path.
A. A car turning around a corner - This is not uniform circular motion because the car is not moving in a complete circle and its speed may not be constant due to the need to slow down for the turn.
B. A cyclist pedaling uphill - This is not uniform circular motion because the cyclist is not moving in a circle. The motion is linear and uphill.
C. A satellite orbiting the Earth - This is an example of uniform circular motion. The satellite moves in a circular path around the Earth at a constant speed.
D. A ball bouncing on the ground - This is not uniform circular motion because the ball's motion is not circular. It moves up and down in a linear motion.
