TermDefinition
SPEED the rate at which an object moves
"AVERAGE SPEED" speed= DISTANCE/TIME
VELOCITY tells the rate an object moves AND in which direction it moves **Think of the air traffic controller
ACCELERATION change in velocity ( speed and direction) of an object **a car going at the same speed but turning or going into a curve
FORCE In science the push or pull between objects
MASS the amount of matter making up an object
INDEPENDENT VARIABLE what you change in your experiment OR it's the variable that you're testing
DEPENDENT VARIABLE It's what we measure: the information you put in the data table *changes the independent variable *doesn't depend on anything else (stands alone)
INERTIA 1) the tendency of ALL objects to RESIST a change in motion 2) the MORE mass an object has the MORE INERTIA it has
NEWTON's 1st LAW OF MOTION effect of balanced and unbalanced forces on an object at rest and on an object in motion
NEWTON's 2nd LAW OF MOTION The amount of force needed to accelerate an object. It depends upon the mass of the object
MASS VS. WEIGHT mass: does not change with location weight: it DOES change with location. A measure of the force of gravity

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.

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.
