Physics Test Questions with Detailed Verified
Answers
A stone dropped from the roof of a single story building
to the surface of the earth
✓✓ speeds up because of an almost constant force
of gravity acting upon it
Two metal balls are the same size but one weighs twice
as much as the other. The balls are dropped from the roof
of a single story building at the same instant of time. The
time it takes the balls to reach the ground below will be
✓✓ about the same for both balls.
The two metal balls of the previous problem roll off a
horizontal table with the same speed. In this situation:
✓✓ both balls hit the floor at approximately the
same horizontal distance from the base of the table.
A boy throws a steel ball straight up. Consider the motion
of the ball only after it has left the boy's hand but before it
touches the ground, and assume that forces exerted by
the air are negligible. For these conditions, the force(s)
acting on the ball is (are):
✓✓ an almost constant downward force of gravity
only.
