The slope of displacement-time graph has the unit:
Correct answer: D. m/s
- A. m
- B. s
- C. m/s²
- D. m/s
Explanation
The slope of a displacement-time graph is given by:Δy/Δx = Δs/Δt, which is equal to velocity. Hence, the correct answer is m/s.Provided below, is an example where Δs, i.e. change in displacement, is given as 17.5 m, and Δt, i.e. change in time, is given as 5 seconds. The above formula is applied to find velocity, by finding the value of the slope.

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.
