The distance travelled by a body is proportional to the square of time. The body is moving with
Correct answer: A. Uniform acceleration
- A. Uniform acceleration
- B. Uniform velocity
- C. Variable acceleration
- D. All of the above
Explanation
The correct answer is Uniform acceleration. When the distance travelled by a body is proportional to the square of time, it describes a scenario where the body is undergoing uniform acceleration. This is derived from the equations of motion in classical mechanics, specifically the second equation of motion: s = ut + (1/2)at2, where s is the distance, u is the initial velocity, a is the acceleration, and t is the time. In this case, the term involving t2 indicates uniform acceleration. Uniform velocity would result in the distance being linearly proportional to time, while variable acceleration would not produce a simple quadratic relationship.

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.
