Physical Science

Newton’s First Law The law of Inertia- An object in motion stays in motion, or an object at rest will stay at rest unless the net force is not zero (unbalanced force)
Newton’s Second Law F=ma, or the force is proportional to the acceleration and to the mass. Unbalanced forces cause acceleration
Newton’s Third Law Interacting objects exert equal and opposite forces on each other
Inertia The resistance an object has to changes in its motion
Air Resistance The force an object experiences as it travels through air that opposes its motion
Static Friction The frictional force a non-moving object experiences, preventing it from moving. Parallel to the surface
Kinetic Friction The frictional force a moving object experiences, opposing its motion. Parallel to the surface.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
