Question

What is the definition of kinetic energy for an object of mass m moving with speed v?
Options
A m v
B m g h
C ½ m v²
Correct Answer
D m v²
Correct Answer

Option C is the correct answer.

Detailed Explanation

Kinetic energy is the energy associated with the motion of an object. It is defined as one-half the product of the object's mass and the square of its speed: KE = ½ m v². It is a scalar quantity.

Hint

Recall the formula for energy of motion. It involves mass and the square of velocity.
