a marble with balanced forces acting on it
B
a marble rolling down a ramp
C
two marbles in a bag
D
a marble on a ruler
2) Select the option that represents potential energy.
A
two marbles colliding
B
a marble rolling along the road
C
a marble at the top of a ramp
D
a marble with unbalanced forces acting on it
3) During a collision, energy can be
A
destroyed
B
energized
C
transferred
D
created
4) Friction, a force that resists motion, transfers energy as
A
small amounts of heat.
B
air resistance and gravity.
C
additional friction.
D
potential energy.
5) Which pair of answers represents what kinetic energy depends on?
A
time and distance
B
velocity squared and mass
C
acceleration and speed
D
speed and mass
6) What is Sir Issac Newton's third law of motion?
A
When a force acts on a mass, acceleration is produced.
B
When a force acts on a mass, the mass increases.
C
Objects at rest and objects in motion will remain at rest or in motion, unless they are acted upon by an unbalanced force.
D
For every action there is an equal and opposite reaction.
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 equal and opposite reaction of an action
B
neither the action nor the equal and opposite reaction
C
both the action and the equal and opposite reaction
D
the action which causes an equal and opposite reaction
8) What will happen to a hockey puck that is sliding along the ice if friction is acting?
A
The puck will move at a constant speed the entire time.
B
The puck will slow down for a while and then move at a slower constant speed.
C
The puck will move at constant speed for a while and then slow down.
D
The puck will move slower and slower the entire time.
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 at constant speed for a while and then slows down
B
The boat moves at a constant speed.
C
The boat moves slower and slower.
D
The boat slows down for a while and then moves at constant speed.
