Newton's Laws

Review of Vocabulary of Newton's Laws

TermDefinition
Force A force is any interaction that, when unopposed, will change the motion of an object.
Unbalanced Force Two forces acting on an object are not equal in size,
Velocity The speed (distance/time) of an object in a specific direction
Momentum The strength or force that something has when it is moving
Friction A force between two surfaces that are sliding, or trying to slide, across each other. It always works in the direction opposite to the direction in which the object is moving, or trying to move.
Gravity The force by which a planet or other body draws objects toward its center.
Mass A measure of the amount of matter in an object
Balanced Force A force that is opposite in direction and equal in size. it is considered to be in a state of equilibrium. When forces are balanced there is no change in direction.
Net Force The sum of all the forces acting on an object.
Inertia The tendency for an object to continue same speed or velocity until another force acts upon it
Acceleration The rate at which velocity changes with time
Newton Force necessary to provide a mass of one kilogram with an acceleration of one meter per second per second.
Tension A force that tends to stretch or elongate something.
Tectonic Of or relating to changes in the structure of the Earth's surface
Newton's First Law of Motion A body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Law of Inertia
Newton's Second Law of Motion A force to be equal to change in momentum (mass times velocity) per change in time. Force=Mass X Acceleration
Newton's Third Law of Motion When two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. Law of action/reaction.
Applied Force A force that is applied to an object by a person or another 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.
