4.5.6.2.2 Required practical 7 — Acceleration and force/mass

What you do (method)

• Use light gates or video to measure speed at different times/positions.
• Calculate acceleration: a = Δv / Δt.
• Plot v–t graph and use gradient for acceleration.

Common mistakes

• Using total time instead of the interval for Δv.
• Not using consistent units (m/s, s).
