Question 3 WAEC_MODEL_QUESTIONS_VOL1 • 2023 • PHYSICS • practical

A student investigates the motion of a toy car moving down a smooth inclined plane. The car starts from rest at the top of the plane. Distances measured along the plane and the corresponding times recorded with a digital stopwatch are given in the table. | Distance (m) | Time (s) | |--------------|----------| | 0.5 | 0.90 | | 1.0 | 1.30 | | 1.5 | 1.65 | | 2.0 | 1.95 | | 2.5 | 2.20 | Using the data, answer the following:

Question Parts

( a )

Plot distance (s) against time (t) and determine the gradient of the best‑fit straight line. State briefly how the gradient is obtained from the data.

( b )

Using the gradient obtained, calculate the average speed of the car and hence determine the acceleration, assuming the motion is uniformly accelerated from rest.

( c )

State two possible sources of error in this experiment and suggest one method to minimise each.
