Which of these objects has kinetic energy?
A
a skateboard rolling up a ramp
B
a car parked on top of a hill
C
a dish placed near the edge of a table
D
a rollercoaster not in use

The object which has kinetic energy is: A . a skateboard rolling up a ramp.

Energy can be defined as the ability (capacity) to do work.

Hence, energy is only measured in Joules (J).

Generally, there are two (2) main types of energy and these are;

In this scenario, the only object that has kinetic energy is a skateboard rolling up a ramp because it is experiencing motion.

On the other hand, a car, dish and a rollercoaster not in use all possess potential energy due to their height or position.

A

Explanation:

Any object in motion has kinetic energy. So, if the skateboard is moving, it has kinetic energy. Hope this helps!
