What is the independent variable in the acceleration of the trolley practical?

The angle of the ramp.

Answer in your head, out loud, or on paper, then tap the card to flip.

How is the acceleration calculated?


a = 2sv2u2


Where:

  • a = acceleration (m/s2)
  • v = final speed (m/s)
  • u = initial speed (m/s)
  • s = displacement (m)

Answer in your head, out loud, or on paper, then tap the card to flip.

Why are light gates used?

To measure the speed of the trolley at two points so the acceleration can be calculated.

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the purpose of the interrupt card?

To trigger the light gates and allow the speeds to be measured accurately.
