A moving body needs:
Correct answer: B. Kinetic energy
- A. Momentum
- B. Kinetic energy
- C. Velocity
- D. Potential energy
Explanation
A moving body needs to have kinetic energy (KE). Because KE = 1/2 mv2 (m = mass, v = speed), the object would need a certain amount of speed. Please note the v does not have equal velocity, and there can still be KE with the velocity being 0 (as in circular motion).Velocity is a both change in speed and direction... so it's not necessary that object is charging direction too

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
