NEWTON'S FIRST LAW OF MOTION: INERTIA

This law states that objects like to keep doing what they're already doing. If something is sitting still, it will stay still unless something makes it move (another force). And if something is already moving, it will keep moving in the same way unless something makes it stop or change direction.

Example 1: A ball will keep rolling on the floor until it bumps into an object or the friction between the ball and the floor slows it down.

Example 2: A book will keep sitting on a table until someone moves it.

NEWTON'S SECOND LAW OF MOTION: FORCE & ACCELERATION

This law says that the bigger the force you use to push or pull something, the faster it will move. And the heavier something is, the harder it is to move. Force is equal to mass × acceleration.

Example 1: If you kick a soccer ball hard, it will move faster than just giving it a little tap.

Example 2: A heavy box will be harder to move than a light box.

NEWTON'S THIRD LAW OF MOTION: ACTION & REACTION

This law says that for every action (push or pull), there is an equal and opposite reaction (push or pull). So if you push on something, it will push back on you with the same amount of force, but in the opposite direction.

Example 1: If you kick a soccer ball, the ball pushes back on your foot with the same amount of force.

Example 2: When you jump off a diving board, the board pushes back on you with the same amount of force that you push down on it.

Drag each explanation to the corresponding Law of Motion/ image.

  • When pushed, the empty cart moves faster and farther than the full cart.

  • The cart stays at rest and the cart moves when pushed.

  • The cart and the person are pushing with equal force in opposite directions.

  • First Law of Motion: Inertia

  • Second Law of Motion: Force & Acceleration

  • Third Law of Motion: Action & Reaction

Dag and drop a description and an example for each law of motion.

  • For every action, there is an equal and opposite reaction.

  • My fingers are still until I move them to type.

  • More force will move an object faster than less force.

  • When I hammer a nail on the wall, the nail pushes back on the hammer.

  • Objects keep doing what they are doing until a force acts upon them.

  • When I kick a soccer ball harder, it moves through the air faster.

  • First Law of Motion: Inertia

  • Second Law of Motion: Force & Acceleration

  • Third Law of Motion: Action & Reaction
