Required practical: force, mass and acceleration

Video coming soon

The key ideas and the summary sheet for this lesson are ready now.

Key ideas

  1. A falling mass on a string over a pulley pulls the trolley; light gates time it.

  2. To vary the force, move masses from the trolley to the hanger so the total mass stays the same.

  3. Acceleration is proportional to force and inversely proportional to mass.

  4. Use light gates, a soft landing and repeats for a top-mark method.
