8th Grade Physics

TermDefinition
Motion The change in an object’s position with respect to time.
Speed The distance traveled by an object in a given amount of time.
Balanced Force The net force on an object is zero and the object’s motion does not change.
Unbalanced Force The net force of an object does not equal zero which results in a change in the motion of the object.
Net Force The sum of all the forces acting on an object.
Magnitude The strength of an object or event.
Force A push or a pull.
Friction The force between objects that affects how easily they move past each other.
Gravity A force that pulls objects together.
Potential Energy Energy at rest or stored energy.
Kinetic Energy Energy in motion.
Velocity Measurement of speed and direction of an object.
Acceleration Speed up, slow down, or change direction (The rate of change in an object's speed.)
Inertia The tendency of a physical object to remain still or continue moving
At Rest The state of an object when it is not in motion
Newton’s First Law of Motion An object at rest stays at rest or an object in motion stays in motion until unbalanced forces act upon it. This is often referred to as Newton's law of inertia.
Newton’s Second Law of Motion Acceleration of an object depends on the object's mass and the magnitude of the force acting upon it (F = ma). This is often referred to as Newton's law of force and acceleration.
Newton’s Third Law of Motion For every action there is an equal and opposite reaction. This is often referred to as Newton's law of action-reaction.

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.
