A mass has constant acceleration, what is true about the force applied on it?
Correct answer: B. Constant but not zero
- A. Constantly increasing
- B. Constant but not zero
- C. Is directly proportional to square of displacement
- D. Is directly proportional to velocity
Explanation
According to F=ma, acceleration and force are both directly proportional to each other. If acceleration is constant then the force applied on the object will also be constant.

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.
