Question 3 IGCSE_MODEL_QUESTIONS_VOL1 • 2018 • PHYSICS • practical

A dynamics cart is released from rest at the top of a smooth inclined plane. The plane makes an angle of 30° with the horizontal and its length is 1.5 m. A motion sensor records the distance travelled by the cart at 0.5 s intervals as shown in the table below. | t (s) | s (m) | |-------|-------| | 0.0 | 0.00 | | 0.5 | 0.60 | | 1.0 | 2.40 | | 1.5 | 5.40 | | 2.0 | 9.60 | Using the data, determine the experimental acceleration of the cart and compare it with the theoretical value. (You may use g = 9.8 m s⁻².)

Question Parts

( a )
Describe the experimental set‑up and the method used to obtain the distance‑time data.
( b )
Calculate the theoretical acceleration of the cart down the plane.
( c )
Determine the experimental acceleration using the data. (i) From the distance‑time relation s = ½ a t² using the final reading. (ii) From the gradient of a velocity‑time graph constructed from the data.
( d )
State two possible sources of error that could cause the experimental value to differ from the theoretical value.
