Slope of distance time graph can never be:
Correct answer: B. negative
- A. positive
- B. negative
- C. zero
- D. constant
Explanation
The slope of a distance-time graph cannot be negative. This is because distance is a scalar quantity and cannot have a negative value. Distance represents the magnitude of displacement and is always positive or zero. Therefore, a negative slope on a distance-time graph would not have any physical meaning. So, option B is the correct option.

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.
