Instructions: Answer all questions to get your test result.
1) Select the option that represents kinetic energy.
A
a marble rolling down a ramp
B
a marble with balanced forces acting on it
C
two marbles in a bag
D
a marble on a ruler
2) Select the option that represents potential energy.
A
a marble at the top of a ramp
B
a marble with unbalanced forces acting on it
C
two marbles colliding
D
a marble rolling along the road
3) During a collision, energy can be
A
created
B
energized
C
transferred
D
destroyed
4) Friction, a force that resists motion, transfers energy as
A
air resistance and gravity.
B
small amounts of heat.
C
potential energy.
D
additional friction.
5) Which pair of answers represents what kinetic energy depends on?
A
acceleration and speed
B
velocity squared and mass
C
speed and mass
D
time and distance
6) What is Sir Issac Newton's third law of motion?
A
Objects at rest and objects in motion will remain at rest or in motion, unless they are acted upon by an unbalanced force.
B
When a force acts on a mass, the mass increases.
C
For every action there is an equal and opposite reaction.
D
When a force acts on a mass, acceleration is produced.
7) When LeBron James jumps, he pushes down on the surface of the court. This is the 'action' that Newton mentions in his Third Law. Based on this information, LeBron James jumping is an example of which part of Newton's Third Law?
A
the action which causes an equal and opposite reaction
B
both the action and the equal and opposite reaction
C
neither the action nor the equal and opposite reaction
D
the equal and opposite reaction of an action
8) What will happen to a hockey puck that is sliding along the ice if friction is acting?
A
The puck will slow down for a while and then move at a slower constant speed.
B
The puck will move slower and slower the entire time.
C
The puck will move at a constant speed the entire time.
D
The puck will move at constant speed for a while and then slow down.
9) Newton's First Law states that
A
Friction slows down all objects.
B
Friction and air resistance stop the motion of all objects.
C
An object continues straight until friction and air resistance stop it.
D
An object will continue at a constant speed unless an external force acts on it.
10) A motor boat is traveling 10 m/s on a sunny calm day. The driver turns off the engine. Apply Newton’s first law to explain what happens to the boat as it glides through the water.
A
The boat moves slower and slower.
B
The boat moves at constant speed for a while and then slows down
C
The boat slows down for a while and then moves at constant speed.
D
The boat moves at a constant speed.
