Forces that produce a non zero net force which changes an objects direction unbalanced forces
The overall force on an object when all individual forces acting on it are added together net force
A unit of measure that equals the force required to accelerate one kilogram of mass a 1 meter per second per second newton
The force that two surfaces exert on each other when they rub against each other friction
A force that pull things toward each other gravity
A measure of the amount of matter in an object mass
The force of gravity on a person or object at the surface of a planet weight

An object that is thrown projectile
The tendency for an object to resist change in motion No inertia
An object at rest will stay at rest and an object in motion will remain in motion until acted upon by an outside force newtons 1st law
A change in speed or direction depends on an objects mass and overall net force acting on the object newtons 2nd law
With every action there is an equal and opposite reaction newtons 3rd law
A characteristic of a moving object that is related to the mass and velocity of the object momentum
In the absence of outside forces,the total momentum of objects that interact do not change law of conservation of momentum

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
