Question 1

What is the method of the practical?

Answer 1

1) Measure the mass of the system (everything).
2) Mark a line to show where the trolley started.
3) Position light gates; one at the start line, one further down the ramp.
4) Attach the 100g slotted mass. Each 100g slotted mass applies a force of 1N.
5) Let the trolley pass the light gates and record the change is speed and time (to calculate acceleration).
6) Repeat, adding on 100g slotted masses each time.
