Graphs of Motion
The displacement-time graph of a moving particle is shown below. The instantaneous velocity of the particle is negative at the point
Show answer and solution
Answer: (a)
- Instantaneous velocity = slope of the tangent to the - graph.
- At C and F the curve is rising (positive slope); at D the slope is zero (maximum).
- At E the curve is falling, so the slope is negative.
- So the answer is (a) E.
