Motion & Forces

Motion & Forces Vocabulary

QuestionAnswer
The state in which one object’s distance from another is changing. Motion
The rate at which velocity changes. A change in speed or direction. Acceleration
The distance an object travels per unit of time. Speed
Energy of motion. Kinetic energy
Stored energy that results from the position of the object. Potential energy
Speed in a given direction. Velocity
The force that pulls objects toward each other. Gravity
The force of gravity on an object at the surface of the planet. Weight
The greatest velocity a falling object can achieve. Terminal velocity
The motion of a falling object when the only force acting on it is gravity. Free Fall
A push or a pull exerted on an object. Force
The overall force on an object when all the individual forces acting on an object are added together. Net force
The force that one surface exerts on another when the two rub against each other. Friction
The tendency of an object to resist any change in its motion. Inertia
The fluid friction experienced by objects falling through the air. Air resistance
A unit of measure that equals the force required to accelerate one kilogram of mass at 1 meter per second per second. Newton
Equal forces acting on an object in opposite directions. Balanced forces
A nonzero net force, which changes an object’s motion. Unbalanced forces
Write the mathematical formula for force. Mass x Acceleration
Write the mathematical formula for acceleration. Force/Mass
Write the mathematical formula for distance. Speed x Time
Write the mathematical formula for speed. Distance/Time
Write the mathematical formula for time. Distance/Speed

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.
