forces and motion

TermDefinition
Acceleration a measure of the change in velocity during a period of time
Contact Force a push or a pull on one object by another object that is touching it
Newton's 2nd Law the acceleration of an object will equals the net Force on the object divided by the objects mass
Friction a contact Force that resist the sliding motion of two surfaces that are touching
Free-Body Diagram a simple model to understand what will happen to an object due to force
Force when you push or pull on an object
Net-Force the combination of all the forces acting on an object
Newton's 1st Law an object in motion will stay in motion and an objects at rest will stay at rest unless acted on by a force
Motion the process of changing position
Displacement the difference between the initial, or starting, position and the final position
Speed a measure of distance an object travels in a given amount of time
Velocity the speed and the direction of a moving object
Vector a quantity that has both magnitude and direction
Reference Point the starting point you choose to describe the location, or position, of an object
Position an objects distance and direction from a reference point
Inertia
Newton's 3rd Law for every action there is an equal and opposite reaction
Force Pair the forces 2 objects apply to each other
Normal Force a push or pull on a object
Elastic Collision when colliding objects bounce off each other
Inelastic Collision if objects collide and stick together such as when 1 football player tackels another
Non-contact Force a force that one object applies to another object without touching it
Gravity an attractive force that exists between all objects that have mass
Field a region of space that has a physical quanity (such as a force) at every point
Weight the gravitational force exerted on an object

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.
