Force and Motion voc

TermDefinition
Inertia - the tendency of all objects to resist any change in motion
Momentum - the product of mass and velocity of an object M = mv
Velocity - the speed of an object in a particular direction
Speed - the rate at which an object moves; speed depends on the distance traveled and the time taken to travel that distance
Deceleration - decrease in speed
Acceleration - the rate at which velocity changes; an object accelerates if its speed, direction, or both change
Gravity - a force of attraction between two objects that is due to their masses
Net force - the force that results from combining all the forces exerted on an object
Force - a push or a pull; all forces have both size and direction
Balanced Force - forces applied to an object produce a net force of zero; do not cause a change in the motion of a moving object
Unbalanced Force - forces applied to an object do NOT produce a net force of zero; produce a change in motion
Work - the action that results when a force causes an object to move in the direction of the force
Friction - a force that opposes motion between two surfaces that are touching
Newton - (N) the SI unit of force
Reference Point - a fixed place on the Earth's surface from which direction and location can be described
Centripetal Force - the force of an accelerating object that moves in a circular path; the force is always directed toward the center of the circle

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.
