# Forces

TermDefinition
force a push or a pull in a particular direction
motion a change in position
friction a force that opposes the motion of one object moving past another
push a force that allows you to move an object away from you
pull a force that allows you to move a object towards you
gravity the force that pulls an object together or toward the ground
balanced forces forces that act together on an object without changing its motion
unbalanced forces forces that do not cancel each other out and that cause an object to change its motion
velocity is the measurement that combines both the speed and direction of a moving objects
speed Is how fast an objects position changes over time
acceleration is the change in velocity over time for an object
momentum Is the product of mass multiplied by velocity
air resistance it increases with velocity but friction usually does not
position is the location of an object
frame of reference is an object or a group of objects which you can measure position or motion
newton first law of motion an object at rest tends to stay at rest and an object in motion unless a outside force is acted upon it
newton second law of motion the greater the force the greater the acceleration
newton third law of motion for every action there is an equal and opposite reaction

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.
