If a constant force is applied to a body, it moves with uniform
Correct answer: C. acceleration
- A. velocity
- B. momentum
- C. acceleration
- D. kinetic energy
Explanation
According to Newton's second law, F=ma, if a constant force is applied to a body, it will accelerate at a constant rate in the direction of the force.Incorrect Options Explanation:(a) velocity: Velocity might change if there's acceleration, not remain uniform.(b) momentum: Momentum changes with acceleration, so it won't remain uniform if there's acceleration.(d) kinetic energy: Kinetic energy may change due to changes in velocity or mass, but it's not directly tied to a constant force resulting in uniform motion.

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.
