Two rocks - one large rock and one small rock - are dropped from the same height at the same time. Which value is the same for the two rocks?
A. the masses of the rocks
B. the time it takes for the rocks to fall
C. the air resistance acting on the rocks
D. the weight of the rocks
B. the time it takes for the rocks to fall
The two rocks are dropped from the same height at the same time, which means they will reach the ground at the same time regardless of their masses or weights. The acceleration due to gravity is the same for both rocks, so they will fall at the same rate.
