#7 In outer space, the net force
needed to keep a satellite in
uniform motion is _____.

#8 Neglecting air resistance,
once a baseball is thrown
horizontally its….
A.
B.
C.
D.

Vertical motion is accelerated
Neither A nor B
Both A and B
#9 In projectile motion, the
object’s horizontal motion is
uniform because _____.
A. There is no net external force action on
the object horizontally
B. The object has inertia
C. Both A and B
#10 In projectile motion, the
object’s vertical motion is
accelerated because _____.
A. There is a net force acting vertically on the
object (the force of gravity)
B. The object has inertia
C. The object seeks to be in its natural state
(at rest on the ground)
#11 In projectile motion
problems, the variable that both
horizontal and vertical have in
common is ____.
A.
B.
C.
D.
Distance
Time
Acceleration
Force
#12 A big rig truck hits a VW bug

decelerates a little because the car
exerts a reaction force…
A.
B.
C.
D.
Much greater than 2200 N
Much less than 2200 N
Of exactly 2200 N
Of an unknown amount since we don’t
know the mass of the car
#13 In space, an astronaut can
more forward by using a
swimming motion.
A. True
