# Laws of Motion 1

Newton's First Law of Motion an object will remain at rest or move in a straight line with constant speed unless it is acted upon by a force
What is the First Law of Motion called? The law of Inertia
What is a force? a push or pull on an object
balanced force forces are in equal but opposite directions, they will cancel each other out
unbalanced force forces that do not cancel out
Newton's Second Law of Motion an object acted on by an unbalanced force will accelerate in the direction of the force with an acceleration given by Newton's Second Law of Motion equation
gravitational force between two objects depends on the masses of the objects and the distances between them
Friction a force that resists sliding motion between two surfaces that are touching
Static Friction keeps an object at rest from moving on a surface when a force is applied to the object
sliding friciton occurs when two surfaces slide past each other
rolling friction makes a wheel roll forward or backward
air resistance mollecules in air collide with the forward-moving surface of an object, slowing its motion down
Newton's Third Law of Motion forces act in equal but opposite pairs

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.
