Question

In uniform circular motion, the factor that remains constant is:

• A. acceleration
• B. momentum
• C. kinetic energy
• D. linear velocity

Answer 1

Answer: (C)

kinetic energy

Answer 2

As in uniform circular motion, the velocity is constant quantity The kinetic energy is $K=\frac{1}{2} m v^{2}$ It is a scalar quantity therefore, kinetic energy is also constant.
