In a billiards game, the white cue ball hits the black ball, moving the black ball to the right while the cue ball moves to the left.
If the action force is applied by the cue ball to the black ball, which force is the reaction force?
the force of gravity on the cue ball
the friction applied by the table to the cue ball
the force applied to the black ball by the cue ball
the force applied by the stick to the cue ball
Angela blows air into a balloon and holds the end of it closed with her fingers. When she lets go of the end of the balloon, Angela observes that the release of the air propels the balloon.
The propelling of the balloon from the release of the air is an example of which of Newton’s laws?
For every action, there is an equal and opposite reaction.
A force of attraction exists between any two objects with mass.
The force of an object is the product of its mass multiplied by its acceleration.
An object in motion tends to stay in motion unless an unbalanced force acts upon it.
During a classroom discussion on motion, the teacher instructs the class to write down something that specifically addresses Isaac Newton’s second law of motion. Which of these responses would best represent the second law?
For every action there is an equal and opposite reaction.
Every object continues at rest unless acted on by outside forces.
Acceleration depends on the force applied and the mass of an object.
Every object attracts every other object and the force is proportional to their masses.
A basketball bounces on the gym floor nine times and finally comes to a rest. Which of these best explains why the basketball rises to a lower height each time it bounces?
Gravity increases as the basketball bounces.
The floor adds energy to the bouncing basketball.
Energy is transferred from the basketball to the floor.
The air inside the basketball is heavier than the surrounding air.
Which of these is an example of Newton’s first law of motion?
A baseball hit with a baseball bat travels faster than a bowling ball hit with the same force.
A basketball bounces on the ground with the same force that the ground pushes up on the ball.
A person jumps to a dock from a boat, and the boat moves away from the dock.
A person standing on a bus moves backward when the bus suddenly moves forward.

Over several years, a tree grows from a young tree into a mature tree.
The amount of grass beneath the mature tree sometimes decreases, forming an area with more soil than grass. Which abiotic factor most likely decreases, causing this change?
nitrogen
oxygen
sunlight
water
In Florida, black bears are found in only a few regions. Roads and highways cross all of these regions. If new road construction continues through the regions occupied by the bears, how will black bear populations most likely be affected?
The populations will increase as the bears spread out to other areas.
The populations will increase because other herbivores will move out.
The populations will decrease due to pollution caused by cars and trucks.
The populations will decrease as they have less area to find food and shelter.
