Question

5.A student vertically stands five books several inches apart in a row. She then pushes the first book with her finger, and a few seconds later, the last book falls. Which statement correctly defines this chain of events?(1 point)
Responses

There are correlation and causation between the force of the finger and the movement of the books.
There are correlation and causation between the force of the finger and the movement of the books.

There is only causation between the force of the finger and the movement of the books.
There is only causation between the force of the finger and the movement of the books.

There is correlation but no causation between the force of the finger and the movement of the books.
There is correlation but no causation between the force of the finger and the movement of the books.

There is only correlation between the force of the finger and the movement of the books.
4.A nonzero net force acts on a moving ball, and the ball comes to a stop. Which statement is correct about the relationship between the net force and the ball's movement?(1 point)
Responses

The net force causes a decrease in acceleration because without the force the ball's velocity would remain the same.
The net force causes a decrease in acceleration because without the force the ball's velocity would remain the same.

A decrease in acceleration causes the net force to be nonzero because causation works in both directions.
A decrease in acceleration causes the net force to be nonzero because causation works in both directions.

The net force causes an increase in acceleration because without the force the ball's velocity would remain the same.
The net force causes an increase in acceleration because without the force the ball's velocity would remain the same.

An increase in acceleration causes the net force to be nonzero because causation works in both directions.
3.A student observes that for the same net force, heavier objects accelerate less. Which statement describes a correct conclusion?(1 point)
Responses

There is a negative correlation between mass and acceleration.
There is a negative correlation between mass and acceleration.

An increase in acceleration causes the mass to increase.
An increase in acceleration causes the mass to increase.

There is a positive correlation between mass and acceleration.
There is a positive correlation between mass and acceleration.

An decrease in acceleration causes the mass to increase.
2.When raindrops form, the force of gravity pulls them toward the ground. Which statement is correct about this chain of events?(1 point)
Responses

The raindrops' acceleration causes the force of gravity.
The raindrops' acceleration causes the force of gravity.

The force of gravity causes the raindrops to accelerate.
The force of gravity causes the raindrops to accelerate.

There is a negative correlation between gravity and raindrops falling.
There is a negative correlation between gravity and raindrops falling.

There is no correlation between gravity and raindrops falling.
1.A line of dominos is knocked down. Which explanation is true? (1 point)
Responses

An increase in acceleration caused an increase in force.
An increase in acceleration caused an increase in force.

An increase in acceleration caused a decrease in force.
An increase in acceleration caused a decrease in force.

An increase in force caused a decrease in acceleration.
An increase in force caused a decrease in acceleration.

An increase in force caused an increase in acceleration.

Answer 1

1. An increase in force caused an increase in acceleration.
2. The force of gravity causes the raindrops to accelerate.
3. There is a negative correlation between mass and acceleration.
4. The net force causes a decrease in acceleration because without the force the ball's velocity would remain the same.
5. There are correlation and causation between the force of the finger and the movement of the books.
