Attach slotted masses to a trolley on a track or glider on an air track so they hang over a pulley
Step 2:
Let trolley move due to the weight of the masses, its flag will pass through two light/photo gates connected to a data logger which will calculate acceleration
ALTERNATIVE 1:
Use one light gate to measure the velocity and measure distance travelled with a metre rule
v2=u2+2as, as u=Om/s: a=v?÷25.
ALTERNATIVE 2:
Use stop clock to measure time taken to travel distance measured with a metre rule
s=ut+¿at?, as u=0m/s, a=2s÷t2
Step 3:
Change the force by removing masses from the hanger and placing them on the trolley. This is crucial as the total mass being accelerated must remain constant
Step 4:
Plot force against acceleration which should show a directly proportional relationship (linear and through origin)
