How would the mass of a roller coaster affect its movement up a hill?

As the roller coaster’s mass increases, more force would be required to push it.

As the roller coaster’s mass increases, less force would be required to push it.

The mass of the roller coaster does not affect the force required to push it.

No force is required to push the roller coaster up the hill so the mass is not important.

In order for the rollercoaster to experience a change in speed or direction, what must be true?

the net (total) force acting on it must be greater than zero

Which of these statements correctly describes what must happen in order for a roller coaster to slow down or come to a stop?

“The forces acting against the roller coaster must be greater than or equal to the force needed to move the roller coaster downhill and forward.”

“The forces acting against the roller coaster must be greater than or equal to the force of friction acting on the roller coaster.”

“The forces acting against the roller coaster must be able to balance out the mass of the roller coaster.”

“The force of gravity must be able to overcome the speed of the roller coaster.”

Which statement correctly describes the forces between a player’s helmet and their head?

The force exerted by the helmet on the head is equal in strength to the force exerted by the head on the helmet.

The force exerted by the helmet on the head is always weaker than the force exerted by the head on the helmet.

The force exerted by the helmet on the head is completely unrelated to the force exerted by the head on the helmet.

The force exerted by the helmet on the head is always stronger than the force exerted by the head on the helmet.

When a football player kicks a ball, which of the following best describes the interaction force between the player's foot and the ball?

The player’s foot exerts a force on the ball, and the ball exerts an equal and opposite force back

The player’s foot exerts a stronger force on the ball compared to the force exerted by the ball on the foot

The player’s foot exerts a weaker force on the ball compared to the force exerted by the ball on the foot

The player's foot exerts a force on the ball, but the ball does not exert a force back.

When a football player collides with another player during a tackle, according to Newton's Third Law of Motion, what can be said about the forces involved?

The players exert equal forces on each other in the opposite direction

The player receiving the tackle exerts a stronger force on the initiating player

The players exert very different forces on each other

The player initiating the tackle exerts a stronger force on the other player

You are designing a new football helmet and need a model that accurately represents the forces that the two players exert on each other's heads during a collision. Which of the four models is the most accurate and why?

Model D because both players will exert equal forces on each other and they will be applied in opposite directions.

Model A because both players will exert equal forces on each other, but they will both be applied to the player with the ball, not the defender.

Model B because the force of the player with the ball is greater than the force of the defender who is trying to stop him.

Model C because the force of the player with the ball is greater, but both forces will be exerted on the defender.

The picture above is a diagram of an egg sitting on a table. The egg is pushing down on the table with a force of 0.5 N. What must be true of the force that the table exerts on the egg?

The force must be exactly 0.5 N

The force must be less than 0.5 N but more than 0 N

The force must be more than 0.5 N

In a collision between two objects, how does the mass of the objects affect the amount of force they exert on each other?

No matter the mass of the objects, they will exert an equal amount of force on each other.

The object with greater mass will exert less force than the object with smaller mass.

The object with greater mass will exert more force than the object with less mass.

The amount of force does not depend on the mass of the objects, it depends on their size.

If the man pushes with an equal amount of force, which object will accelerate more?

Lawnmower because it has less mass

Lawnmower because it has more mass

When you hit a tennis ball with a racket...

The ball and racket exert the same force on each other

The ball exerts more force on the racket

The racket exerts more force on the ball

It depends on how hard you hit it

Two students with different masses are sitting in roll-y chairs. The lighter one uses his feet to push the other

The lighter student will move faster because he has less mass

The heavier student will move more because he is being pushed

They will move with the same speed

The heavier student shouldn't move at all

An archer shoots an arrow. The action force is the bowstring against the arrow, the reaction force is...

The arrow's push against the bowstring

the grip of the archer's hand on the bow

How will this object move?

The object will move to the right.

The object will move to the left.

The object will remain stationary.

How will this object move?

It will move in both directions
