Force and Motion

TermDefinition
Kinetic energy energy that an object has due to its motion.
Potential energy the energy an object has because of its position; also, the internal stored energy of an object.
Energy the ability to do work or cause change.
Law of Conservation of Energy energy can neither be created nor destroyed - only transferred from one form of energy to another.
Mass the measure of the amount of matter in an object.
Energy transfer a change from one form of energy to another.
Force a push or pull that acts upon an object as a result of that object's interactions with its surroundings.
Balanced forces two forces acting on an object are equal in size but act in opposite directions; a stationary object stays still but a moving object continues to move at the same speed and in the same direction.
Unbalanced forces a force that causes a change in the motion of an object.
Newton’s 1st Law this law states that an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force.
Inertia the tendency of an object to resist a change in motion.
Newton’s 2nd Law this law states that the greater the mass of the object being accelerated, the greater the amount of force needed to accelerate the object.
Newton’s 3rd Law this law states that for every action, there is an equal but opposite reaction.
Weight the force that an object is attracted to another object and depends on its mass and the strength of the gravitational pull.
Friction the force that 2 surfaces exert on each other when they rub against each other and can create heat.
Acceleration the rate at which velocity (speed) changes.
Net Force the sum of all the forces acting 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.
