TermDefinition
Gravity The acceleration of a falling object, is due to the force of gravity. (Between the object and the Earth)
Law of Universal Gravitation States that all object in the universe attract each other by the force of gravity/ The size of the force depends on two factors. : the masses of the object increase.
Weight Weight is a measure of the force of gravity on an object.
Weight Equation Weight=Mass*Acceleration due to gravity. W=M*G
Work Work, is a force acted over a distance, to change an objects position.
Power How fast you can do work.
6 Simple Machines. 1. Pulley 2. Wedges. 3. Levers. 4. Screws. 5.Wheel & Axle 6. Incline Plane
Newton's Gravitation Law & Weight Weight is a downward force that that is dependent on gravitational pull & mass. It causes an acceleration of 9.8 m/s2 (squared)
Inertia (Newton called this tendency of objects to remain in motion or stay at rest(Inertia) Inertia is the property of matter that tends to resist any change in motion.
Friction Friction is a force that acts in a direction opposite to the motion of the moving object.
Types of Friction 1.Rolling Friction 2.Sliding Friction 3.Fluid Friction
Force Is a push or pull to make it move. (cause things to move)

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.
