Science Lesson 8

TermDefinition
Reference Point The starting point you use to describe the motion or position of an object
Position An object's distance and direction from a reference point
Displacement The difference between the initial, or starting, position and the final position of an object that has moved.
Motion The process of changing position
Speed The distance an object moves divided by the time it takes to move that distance.
Velocity The speed and the direction of a moving object
Acceleration The measure of the changes in velocity during a period of time
Distance - time graph A graph that shows how distance and time are related
Speed - time graph A graph that shows the speed of an object on the y - axis and the time on the x - axis
Force A push or pull on an object
Contact force A push or pull on one object by another that is touching it
Noncontact force A force that one object applies to another without touching it
Gravity An attractive force that exists between all objects that have mass
Friction A contact force that resists the sliding motion of two surfaces that are touching
Air resistance The frictional force between air and objects running through it
Newton's first law of motion Law that states that if the net force acting on the object is zero, the motion of the object does not change
Newton's second law of motion 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
Newton's third law of motion Law that states 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.
