TermDefinition
acceleration A measure of the change in velocity during a period of time
contact Force a push or pull on one object by another object that is touching it.
Newton's 2nd Law Law that states that the acceleration of an object divided by the objects mass.
Friction A contact Force that resists 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 a force.
Force A push or pull on an object.
Net Force The combination of all the forces acting on an object.
Newton's 1st Law an object at rest will stay at rest and an object in motion will stay in motion unless a force acts on the object.
Motion The process of changing position.
Displacement The difference between the initial or starting position and the final position.
Speed A measure of the 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 or an object.
Position an objects distance and direction from a reference point.
Inertia a tendency to do nothing or to remain unchanged.
Newton's 3rd Law When an object applies a force on another object the second object applies a force of the same strength on the first object but the force is in the opposite direction.
Force Pair the forces two objects apply to each other.
Normal Force The force that pushes perpendicular to the objects surface.
Elastic Collision when colliding objects bounce off each other.
Inelastic Collision a collision where total kinetic energy is not conserved
Non-contact Force a force that one object applies to another object without touching it.
Gravity an attractive forces that exists between all objects that have mass.
Field a region of space that has a physical quantity (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.
