When 1 N force acts on 1 kg body that is able to move freely, the body receives:
Correct answer: B. An acceleration of 1 m/s2
- A. A speed of 1 m/s
- B. An acceleration of 1 m/s2
- C. An acceleration of 980 cm/s2
- D. An acceleration of 1 cm/s2
Explanation
This is the following solution: According to the second law of motion: F = ma Given F = 1 N, m = 1 kg. So a = 1 m/s2

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.
