AFCI Question 1

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.

Which animation best represents how the balls would fall to the ground below?

Animation A
Animation B
Animation C
Animation D
Animation E

AFCI Question 3

A stone is dropped from the roof of a single story buliding.

Which animation best represents how the stone would fall to the ground below?

Animation A
Animation B
Animation C
Animation D
Animation E

AFCI Question 13

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 the forces exerted by the air are negligible.

For these conditions, the forces(s) acting on the ball are

a downward force of gravity along with a steadily decreasing upward force.
a steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point; on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth.
an almost constant downward force of gravity along with an upward force that steadily decreases until the ball reaches its highest point; on the way down there is only a constant downward force of gravity.
an almost constant downward force of gravity only.
none of the above. The ball falls back to the ground because of its natural tendency to rest on the surface of the earth.

AFCI Question 17

An elevator is being lifted up an elevator shaft at a constant speed by a steel cable as depicted in the animation. All frictional effects are negligible

While the elevator is rising, forces on the elevator are such that:

the upward force of the cable is greater than the downward force of gravity.
the upward force of the cable is equal to the downward force of gravity.
the upward force of the cable is is smaller than the downward force of gravity.
the upward force of the cable is greater than the sum of the downward force of gravity and the downward force due to the air.
none of the above (The elevator goes up because the cable is being shortened, not because an upward force is exerted on the elevator by the cable).
