Physics for IGCSE & O level - Forces And Motion (Section 4 - No. 1)
Which of the following correctly describes free fall?
Motion solely under the influence of gravity.
Constant acceleration downwards.
Presence of air resistance.
Objects of different masses fall at different rates.
Explication
Free fall is solely due to gravity with constant acceleration. Air resistance is absent, and all objects fall at the same rate in vacuum.
