1st law

If a student is about to release a ball and let it drop, the ball has –

potential energy

If you walk on a log that is floating in the water, the log moves backward.

3rd Law

Potential or Kinetic: an apple on the table

potential

0 N balanced

Max and Mia are walking toward one another. They bump into each other, and they both fall backwards.

3rd Law

Friction causes moving objects to stop.

True

True or False: The more a rubber band is stretched, the more kinetic energy it has.

False

Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction.

3rd Law

2nd law

4 N <-- unbalanced

when a car drives up a hill, what has been increased?

potential energy

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.
