Science

TermDefinition
Friction is a force that resists the sliding motion of two surfaces that are touching.
Net force is the sum of all the forces acting on an object.
Newton’s First Law of Motion States that an object in motion will stay in motion and an object at rest will stay at rest.
Newton’s Third Law of Motion States that when an object applies a force on another object, the second object applies a force of the same strength.
Force Pair is the forces two objects apply to each other.
Normal Force is the force that pushes perpendicular to the object's surface.
Elastic Collision is when colliding objects bounce off each other.
Noncontact force is a force that one object can apply to another object without touching it.
Gravity is an attractive force that exists between all objects that have mass.
Weight is the gravitational force exerted on an object.
Reference Point is the starting point you choose to describe the location, or position, of an object.
Position is an object's distance and direction from a reference point.
Motion is the process of changing position.
Displacement is the difference between the initial, or starting, position and the final position.
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.
Acceleration is a measure of the change in velocity during a period of time.
Force is a push or a pull on an object.
Constant Force is a puch or a pull on one object by another object that is touching it.
Newton’s Second law of motion States that the acceleration of an object equals the net force on the object divided by the object’s mass.

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.
