The displacement-time graph of a particle moving with uniform velocity is
Correct answer: B. straight line
- A. parabola
- B. straight line
- C. circle
- D. hyperbola
Explanation
When a particle moves with uniform velocity, its displacement-time graph is a straight line. This is because the displacement of the particle increases linearly with time.Incorrect Options Explanation:(a) Parabola: A parabolic graph typically represents motion with acceleration, not uniform velocity.(c) Circle: Circular motion is characterized by constant speed but changing direction, not uniform velocity.(d) Hyperbola: Hyperbolic graphs usually represent more complex motions involving acceleration or deceleration.

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.
