A 1 kg ball is moving at 12 m/s – what is its kinetic energy?

Kinetic energy is the energy possessed by a body due to its motion.

The formula for kinetic energy is:

KE = (1/2) m v²

Where:

• m = mass of the object
• v = velocity

Given:
m = 1 kg
v = 12 m/s

Substituting the values:

KE = (1/2) × 1 × (12)²
KE = (1/2) × 144
KE = 72 joules

Therefore, the kinetic energy of the ball is 72 J.
