Forces: Motion Practical

Question 1

State equipment used

Answer 1

trolley 
piece of card
light gates
pulley
hook
masses
string

Question 2

State measurements required

Answer 2

length of card
distance between light gates
time taken to pass between light gates
weight of masses + hook

Question 3

State the equation used (with measuements)

Answer 3

speed = distance x time

Question 4

State how to investigate effect of Mass

Answer 4

control: masses on the hook (accelerating force)
independent: masses on the trolley (increase system mass)

dependent: average acceleration for each mass

Question 5

State the result of a change in Mass

Answer 5

increased system mass = decreased acceleration of the trolley

Question 6

State how to investigate effect of Force

Answer 6

control: total system mass
independent: masses on the hook (accelerating force)
[all masses begin on the trolley and get transferred to the hook]
dependent: average acceleration for each force

Question 7

State the result of a change in Force

Answer 7

increased force = increased the acceleration of the trolley
