The acceleration of any object in response to the gravitational attraction between the Earth and the object
Apparatus setup to measure the distance and time for the ball bearing to drop
This method is an example of the procedure for varying the height the ball-bearing falls and determining the time taken – this is just one possible relationship that can be tested
Example Table of Results
The graph of 2h/t against t produces a straight-line graph where the acceleration is the gradient
A student investigates the relationship between the height that a ball-bearing is dropped between two light gates and the time taken for it to drop.
Calculate the value of g from the table.
Step 1: Complete the table
Step 2: Draw graph of 2h/t against time t
Step 3: Calculate the gradient of the graph
