Forces and Motion

TermDefinition
Gravity Force that pulls everything and everybody towards Earth
Mass is the amount of matter in an object
Weight a measure of the force Earth's gravity on the mass of the object or a living thing
Push to use force to move someone or something away from you
Pull to hold onto and move someone or something toward yourself
Friction force that opposes movement between touching surfaces and always acts against the direction of motion
Force push or pull applied to an object
Motion the action or process of moving or of changing place or position; movement
Velocity the speed of something in a given direction.
Inertia When something remains at rest
Speed the rate at which someone or something is able to move or operate.
Position a place where someone or something is located or has been put.
Axis an imaginary line about which a body rotates.
Balanced Forces equal in size and opposite in direction
Unbalanced Forces the force applied in one direction is greater than the force applied in the opposite direction.
Acceleration a vehicle's capacity to gain speed within a short time.
Direction a course along which someone or something moves.
Air Resistance the force acting on an object that is moving through air flowing in the opposite direction. The air “resists” the object's movement, slowing it down by friction that is created as the object collides with air molecules.
Momentum the force or speed of an object in motion, or the increase in the rate of development of a process
Resist a measure of the opposition to current flow
Newton's 1st Law every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
Newton's 2nd Law the force on an object is equal to its mass times its acceleration.
Newton's 3rd Law 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:

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.
