Forces

The video shows how a glider on an air track can be used to investigate the relationship between force and acceleration.

Can you think of improvements that can be made to the experiment shown?

• The total mass in the system needs to remain constant when adding masses to the mass holder
• This can be achieved by sticking masses to the glider and then moving them one by one to the mass holder
• The track needs to be horizontal - this should be tested before starting the experiment

How could you change the experiment to investigate how changing the mass affects the acceleration?
