When energy moves from one object to another. 👉 Example: When you kick a soccer ball, energy moves from your foot to the ball.

Forces that are the same size (strength) and cancel each other out. 👉 Example: Two people pushing a box equally from opposite sides and it doesn’t move.

A force that pulls objects toward each other, especially toward Earth. 👉 Example: When you drop a pencil, gravity pulls it to the ground.

A force that slows things down when two surfaces rub against each other. 👉 Example: Your bike slows down when you stop pedaling because of friction.

Forces that are not the same strength, causing an object to move. 👉 Example: One person pushes a box harder than another, so the box moves.

A force that moves something away from you. 👉 Example: Pushing a door open.

A force that brings something closer to you. 👉 Example: Pulling a wagon.

Forces that are equal and opposite, so there is no change in motion. 👉 Example: A book sitting still on a table.

Forces that are not equal, causing a change in motion (start, stop, or change direction). 👉 Example: Kicking a ball and making it move.

When two or more objects affect each other. 👉 Example: A bat hitting a baseball.

A way to try something out to see what happens or to learn more. 👉 Example: Testing how far different balls roll.

The amount of matter (stuff) in an object. 👉 Example: A bowling ball has more mass than a tennis ball.

When an object changes position or moves. 👉 Example: A car driving down the street.

A force that happens when objects are touching. 👉 Example: Pushing a chair.

A force that can act on objects without touching them. 👉 Example: Gravity pulling you down.

To use a force on something. 👉 Example: Applying force to push a box across the floor.
