Force &Newton's Laws

Force & Newton's Laws

TermDefinition
Force is a push or a pull on an object.
Contact Force is a push or a pull on one object by another that is touching it
Noncontact Force is a force that an object can apply to another without touching it.
Gravity is an attractive force that exists between all objects that have mass.
Mass is the amount of matter in an object.
Weight is the gravitational force exerted on an object.
Friction is a force that resists the motion of two surfaces that are touching.
Net Force is the combination of all the forces acting on an object.
Balanced Forces are forces acting on an object that combine and form a net force of zero.
Unbalanced Forces are forces acting on an object that combine and form a net force that is not zero
Newton's First Law of Motion states that the net force on an object is zero, the motion of an object does not change.
Inertia is the tendency of an object to resist a change in it's motion.
Newton's Second Law of Motion states that the acceleration of an object is equal to the net force acting on the object divided by the object's mass
Circular Motion is any motion in which an object is moving along a curved path.
Centripetal Force is in a circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve.
Newton's Third Law of Motion states when one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object.
Force Pair is the forces two apply to each other.
Momentum is a measure of how hard it is to stop a moving object.
Law of Conservation of Momentum states that the total momentum of a group of objects stays the same unless outside forces act on the 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.
