As you push a box across a floor at a constant velocity, the friction acting on the box

acts in the direction opposite of motion.

An astronaut drops a hammer and feather simultaneously on the moon, which will hit first?

Neither. They will both hit the ground at the same time.

An astronaut travels to the moon, how does her mass on the moon compare to her mass on earth?

her mass is the same on the moon.

As an astronaut travels far away from Earth, her weight

decreases because gravity decreases

Answers

1
If a force of 12 N is applied to an object with a mass of 2 kg, the object will accelerate at
6 m/s2
12 m/s2
24 m/s2
0.17 m/s2
2
The property of matter that resists changes in motion is called
friction
weight
inertia
gravity
3
When a pair of balanced forces acts on an object, the net force that results is
greater in size than one of the forces.
equal in size to one of the forces.
equal to zero.
greater in size than both forces combined.
4
The SI unit of force is the
meter
kilogram
newton
joule
5
As you push a box across a floor at a constant velocity, the friction acting on the box
acts in the direction of motion.
is less that the pushing force
acts in the direction opposite of motion.
equals the weight of the box
6
Which of the following relationships is correct?
1 N = 1 kg·m
1 N = 1 kg·m/s2
1 N = 1 kg·m/s
1 N = 1 kg
7
The forces acting on a falling leaf are
weight and rolling friction.
gravity and static friction.
gravity and air resistance.
air resistance and fluid friction
8
An astronaut drops a hammer and feather simultaneously on the moon, which will hit first?
Both will float, since there is no gravity on the moon.
The feather will hit the ground first.
Neither. They will both hit the ground at the same time.
The hammer will hit the ground first
9
An open parachute helps save a falling sky diver by
increasing the terminal velocity.
decreasing the weight of the diver.
increasing the air resistance
reducing air resistance
10
The acceleration of an object equals the net force acting on the object divided by the object’s
mass
momentum
weight
velocity
11
An orange might roll off your cafeteria tray when you stop suddenly because of
the centripetal force acting on the orange.
the orange’s inertia.
the balanced forces acting on the orange.
the friction forces acting on the orange.
12
When an unbalanced force acts on an object,
the inertia of the object increases.
the weight of the object decreases
the object’s motion does not change.
the object accelerates.
13
An astronaut travels to the moon, how does her mass on the moon compare to her mass on earth?
her mass is less on the moon
her mass is the same on the moon.
her mass is more on the moon
14
As an astronaut travels far away from Earth, her weight
remains the same because her mass remains the same.
decreases because gravity decreases
increases because gravity increases.
decreases because her mass decreases.
15
In which of the following are action and reaction forces involved?
when a tennis racket strikes a tennis ball
when rowing a boat
when walking down the hall
all of the above
