Lesson details
Lesson outcome
I can explain how to measure acceleration accurately.
Show transcript
A dynamics trolley has a steady acceleration down a steep ramp.
Acceleration = change of velocity ÷ time and change in velocity = final velocity – initial velocity
Light gates can improve accuracy of measurement of instantaneous velocity and reduces random errors.
For a fair test, total mass of the system must be kept constant.
A compensated ramp can counteract the effect of friction.
