# Newton Three Laws of

### Newton's 1st, 2nd and 3rd law of Motion

The First Law of motion is also called what? The Law of Inertia
Inertia depends on what? Mass
What are two forces on Earth that are almost always present? Gravity and Friction
What is Inertia? A resistance to a change in motion
What kind of forces cause an object to move? Unbalanced Forces
What is the greatest velocity a falling object reaches? Terminal Velocity
What causes you to move forward when your car suddenly stops? inertia
What is friction? A force that works against motion by slowing down an object
Sliding friction occurs when two solid surfaces slide over eachother
Rolling friction occurs when a object rolls over a surface.
Fluid friction when an object moves through a liquid or gas
First Law of Motion states: an object at rest will remain at rest and an object in motion will remain in motion at constant velocity unless an unbalanced force acts upon it.
Second Law of Motion is written... force= mass x acceleration
Free fall (concept) falling solely due to the pull of gravity
Projectile motion when any object is thrown in the air and gravity and air resistance are the only forces acting on it
Gravity force that pulls things toward the center of the Earth
Newton's Law of Universal Gravitation all objects in the universe attract each other by 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.

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.
