Stack #4624822

QuestionAnswer
displacement The difference between the initial, or starting position and final position.
speed a measure of a distance an object travels in the given amount of time.
velocity speed and direction of a moving object.
vector a quantity that has both magnitude and direction.
reference point the starting point.
position an object distance and direction from the reference point.
motion the progress of changed position
Acceleration a measure of the change in velocity during a period of time.
force A push or a pull on an object.
Contact force is a push or a pull on one object by another object that is touching it.
Newton's 2nd law States that the acceleration of an object equals the net force 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 object due to a force.
Net force the combination of all the forces acting on an object.
Newton's first 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 when an object
Non contact force a force that one object applies to another object without touching it.
Gravity an attractive force that exists between all objects that have mass.
Field A region of space that has physical quantity (such as a force) at every point.
Weight The gravitational force exerted on a object.
Motion the process of changing positions.
Force pair The forces two objects apply to each other.
Elastic Collision when colliding objects bounce off each other
Inelastic Collision A Collision in which where there is a loss of kinetic energy.
inertia the inherent resistance of any physical object to change its state of motion or rest, directly proportional to its mass.

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.
