1.5 Motion practical question 1
The photograph shows a toy called a marble run.
A student lifts a marble from the table to the top of the marble run at point A. They release the marble from point A and it rolls through pipes to reach the bottom of the marble run at point B.
The marble leaves the marble run at point B and rolls across the table.
As the marble rolls, energy is transferred due to the different forces acting on the marble.
The student wants to measure how much energy the marble loses as it moves from point A to point B .
The student needs to measure the speed of the marble as it leaves the marble run at point B .
Describe a method the student could use to measure this speed.
