force and motion

TermDefinition
Reference point The starting point you choose to describe the location, or position of an object
Position an object's distance and direction from the reference point
motion the process of changing position
Displacement The difference between the initial point to the final position
Speed a measure of the distance an object travels in a given time
Velocity the speed and direction of an object in motion
Vector A quantity that has both magnitude and direction
Inertia an object's ability to resist any change in motion
Force Pair the forces two objects apply to each other
Normal Force the force that pushes perpendicular to the object's surface
elastic collision When colliding objects bounce off each other
inelastic collision A collision in which there is a lost of kinetic energy
Non Contact Force A force that an object applies to another object without touching it
Gravity An attractive force that exist between all objects with mass
Field a region of space that has physical quantity
Weight The gravitational force exerted on an object
Acceleration A measure of the change in velocity during a period of time
Contact Force A push or a pull on one object by another object that is touching it
Newton 2nd Law Law that states that the acceleration of an object is equal to the net force exerted on the object divided by the object's mass
Friction A contact force that resists the sliding motion of two surfaces that are touching
Free-body Diagram A simple model to understand what will happen to an abject do to a force
Force A push or a pull on an object
Net force the combination of all forces acting on an object
Newton's 1st Law an object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on the object
Newton's 3rd Law for every action there is an equal and opposite reaction

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.
