Forces and Motion

QuestionAnswer
Gravity is a force hat pulls everything and everybody towards earth
Mass the amount of matter in an object
Weight a measure of the force Earth's gravity has on the mas of the object or living thing.
Air Resistance the force of air that slows down falling objects
Newton's 1st Law An object at rest stays at rest and an object in motion stays in motion UNLESS acted on by an outside force
Newton's 2nd Law More Force= More Acceleration Less Force= Less Acceleration More Mass= Less Acceleration Less Mass= More Acceleration
Newton's 3rd Law For every action there is an equal and opposite reaction
force strength or power exerted upon an object.
push to use force to move (someone or something) forward or away from you
pull to hold onto and move (someone or something) in a particular direction and especially toward yourself
friction the force that causes a moving object to slow down when it is touching another object.
motion the action or process of moving or of changing place or position; movement
inertia the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force.
speed the rate at which someone or something moves or travels.
position the place where someone or something is in relation to other people or things.
axis the imaginary straight line that something (such as the Earth) turns around.
unbalanced force are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving.
acceleration the rate at which the speed of a moving object changes over time
direction a course along which someone or something moves
velocity the speed of something in a given direction
momentum the quantity of motion of a moving body, measured as a product of its mass and velocity
resist withstand the action or effect of
deceleration reduction in speed or rate

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.
