Exam points

  • State or rearrange a = (v - u)/t for acceleration, velocity change and time.
  • Calculate final velocity, acceleration or time after substituting values with correct units.
  • Apply motion formulae to rockets, protons or ink-drop contexts with powers of ten.

1.6 Acceleration equation question 1

[Maximum number: 2]

A student does an experiment to determine the acceleration due to gravity, g.
The diagram shows the apparatus used.

Figure for Question 1.6 Acceleration equation question 1 — Edexcel IGCSE Physics

This is the student's method.
- connect both light gates to a data logger
- drop a steel ball from rest at the top of the transparent tube
- record the speed of the ball at each light gate
- record the time taken for the ball to fall from light gate A to light gate B

The box shows the data recorded by the data logger.
speed at A =1.45 m/s=1.45 \mathrm{~m} / \mathrm{s}
speed at B =4.20 m/s=4.20 \mathrm{~m} / \mathrm{s}
time from A to B=0.286 s\mathrm{B}=0.286 \mathrm{~s}

Show that the acceleration of the steel ball is approximately 9.6 m/s^2.

acceleration = ............ m/s^2
