Force and Motion Voc

Vocabulary for force and Motion

TermDefinition
Force A push or pull in a specific direction.
Net Force The combination of all forces acting on an object.
Friction A force that OPPOSES motion between two surfaces that are touching.
Law of Universal Gravitation The law that describes the relationships between gravitational forces, mass, and distance which applies to all objects in the universe.
Gravity The force of attraction between objects that is due to their masses such as the Earth pulling objects toward its center.
Newton (N) The unit used for measuring force.
Spring Scale The tool used to measure forces.
Weight A measure of gravity force on objects which values can change with the location of objects in the universe.
Balanced forces Happens when the net force is zero and the forces are balanced causing NO CHANGE in the position of an object.
Unbalanced forces Happens when the net force is greater than zero and CAUSES CHANGES in the position of an object's motion.
Mass The amount of matter in an object; its value DOES NOT CHANGE with its location in the universe.
Distance A measurement of length between two points.
Speed The rate an object moves that depends on the distance traveled and the time it takes. Average speed is total distance divided by total time.
Velocity The SPEED of an object in a particular direction.
Motion An object's change in position relative to a reference point over a period of time.
Acceleration The RATE at which velocity changes with either an increase, decrease, stop, or change of direction.
Positive Acceleration An increase in speed.
Negative acceleration or deceleration A decrease in speed.
Newton's First Law of Motion Law of Inertia. An object at rest stays at rest or an object in motion stays in motion at a speed in a straight line unless another force acts on it.
Newton's Second Law of Motion The amount of force needed to make an object change its acceleration depends on the MASS of the object AND the FORCE required.
Newton's Third Law of Motion For every action (or force), there is an equal and opposite reaction (or force).

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.
