A student inflates a balloon attached to a plastic straw. A string is threaded through the straw and tied to opposite ends of the room. When the air in the balloon is released, the balloon travels the length of the string. Which of Newton's laws explain this?
The law of action-reaction
Newton's law of magnetism
The law of force and acceleration
The law of gravity
Which best explains the law of force and acceleration (Newton's 2nd Law of Motion)
Restraints keep passengers from falling out of a roller coaster
Riders must be certain heights so they have enough mass to ride
A larger force will be required to accelerate a roller coaster with more people
A roller coaster that goes up must also come down due to the force of gravity
If a bird hit your windshield on your car, the force of the car on the bird equals
the force of the bird on your car.
the force of the car on the brid
an elastic collision on the windshield
a noncontact force acting on the windshield
A player hits a ball with a bat. The action force is the impact of the bat against the ball. The reaction force is...
The grip of the player's hands on the ball
the air resistance of the ball
the force of the ball against the bat
What is the reaction force to a foot pushing down on the floor?
The foot going through the floor
The floor pushing back against the foot
The floor breaking to the foot
What happens when two objects, such as a baseball and a bat, collide?
One remains still while the other one moves in the same direction.
They will hit each other with the same force in opposite directions.
They hit each other with unequal force in opposite directions
They hit each other with the same force in the same direction.
What does an object do when it accelerates?

It moves in the opposite direction
It changes speed and direction
All the answers are correct
What determines an object’s mass?
amount of matter

When two objects with unequal mass collide, what will they do?
accelerate at different rates
accelerate in the same direction
come to a complete stop
continue at the same velocity

The softball has more mass than the volleyball
The softball and the volleyball have equal mass
The volleyball has more mass than the softball
It is impossible to compare the mass of the softball and the volleyball
When a car accelerates forward, what is the equal and opposite reaction?
