Every object continues in a state of rest, or in a state of motion in a straight line at constant speed, unless it is compelled to change that state by forces exerted on it Newton's first law
The acceleration produced by a net force on an object is directly proportional to the net force, is in the same direction as the net force, and it inversely proportional to the mass of the object. In symbols, F = ma Newton's second law
To every action there is always an opposed equal reaction newton's third law
the distance traveled per unit of time speed
the rate at which velocity changes with time; the change in velocity may be in magnitude, or in direction, or in both. acceleration
the speed of an object with specification of its direction of motion velocity
the vector that specifies the change in position of a point or a particle in reference to a previous position. displacement
objects at rest tend to remain at rest. inertia
pushes or pulls force
a machine is a device for multiplying forces or simply changing the direction of forces simple machine
work becomes more efficient - easier than physical labor mechanical advantage

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
