Physics - U2 L13 - Correlation and Causation

1) A line of dominos is knocked down. Which explanation is true?

An increase in force caused an increase in acceleration.

2) When raindrops form, the force of gravity pulls them toward the ground. Which statement is correct about this chain of events?

The force of gravity causes the raindrops to accelerate.

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?

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

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.

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

3) A student observes that for the same net force, heavier objects accelerate less. Which statement describes a correct conclusion?

There is a negative correlation between mass and acceleration.
