Question 1
MotionThe distance travelled by a particle starting from rest is plotted against the square of the time elapsed from the commencement of motion. The resulting graph is linear, the slope of this graph is a measure of
- A.initial displacement
- B.initial velocity
- C.acceleration
- D.half the acceleration
- E.half the initial velocity
Show the answer and explanation
Answer: D (half the acceleration)
Explanation
From rest, s = ½at², so a graph of s against t² is a straight line with slope ½a: half the acceleration.
