There is no atmosphere on the Moon.
An astronaut on the Moon drops a feather and a hammer from the same height at the same time. They both accelerate downwards at and they hit the ground at the same time.
The weight of the hammer is much larger than that of the feather.
Explain, in terms of their weights and masses, why their accelerations are equal.
Both the feather and the hammer take to fall to the ground from rest.
Calculate the speed of the objects as they hit the ground.
speed = ______
On Fig. 1.1, draw the speed-time graph for the fall. At the correct position on the y-axis, write the value of the speed at time .
Using the speed-time graph in (b)(ii), determine the height from which the objects are dropped.
height = ______
