Question

Two particles are simultaneously in free fall in the same uniform gravitational field. Which statements are correct while both remain in flight?

G1 Physics · Accepted Answer

Both particles have the same acceleration −g. Hence relative acceleration = 0. Therefore relative velocity is constant and relative separation varies linearly with time. Any collision time obtained from initial separation + relative velocity × time = 0 contains no g. All four statements are correct.
