Forces And Motion

Vocabulary

TermDefinition
the starting point you choose to describe the location or position of an object reference point
an objects distance and direction from a refrence point position
is the process of changing position motion
the difference between the initial, or starting position,and the final position Displacement
a measure of the distance an object travels in a given amount of time speed
the speed and direction of a moving object velocity
a quantity that has both magnitude and direction Vector
a push or pull on one object by another object that is touching it contact force
law that states that the acceleration of an object is equal to the net force exerted on the object divided by the objects mass newtons 2nd law
a contact force that resists the sliding motion of two surfaces that are touching friction
a simple model to understand what will happen to an object due to a force free-body diagram
a measure of the change in velocity during a period of time by an increasing volume of speed Acceleration
a push or pull on an object Force
the combination of all forces acting on an object Net Force
an object at rest stays at rest,and an object in motion will stay in motion unless a force acts on the object Newtons First law
the natural tendency of an object to resist changes in its state of motion,including changes to speed or direction Inertia
when an object applies a force on another object,the second object applies a force of the same strength of the first object but the force is in the opposite direction newtons first law
fthe forces two objects apply to eachother force pair
the force that pushes perpendicular to the objects surface normal force
when colliding objects bounce off each other Elastic Collision
a Collision where total kinetic energy is not conserved typically transforming into internal energy like heat,sound or material deformation Inelastic Collision
a force that one object applies to another object without touching it Non-contact force
an attractive force that exists between all objects that have mass Gravity
a region of space that has a physical quantity at every point Field
the gravitational force exerted on an object weight

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.
