QuestionAnswer
speed is a measure of the distance an object travels in a given amount of time
velocity is the speed and direction of a moving object
vector is a quantity that has both magnitude and direction
displacement is the difference between the initial, or starting, position and the final position
newton's 3rd law of motion when an object applies a force on another object, the second object applies force of the same strength on the first object but the force is in the opposite direction
force pairs the forces two objects apply to each other
normal force the forces that pushes predicular to the objects surface
elastic collision when colliding objects bounce off each other
Acceleration a measure of the change in velocity during 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 is equal to the net force exerted on the object divided by the object's 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 a 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
Reference Point the starting point you choose to describe the location, or position, of an object
Position an object's distance and direction from a reference point
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 physical quantity (such as a force) at every point
Weight the gravitational force exerted on an object
Inertia
inelastic collision

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.
