Laws of Motion

QuestionAnswer
The tendency of an object to resist a change in motion Inertia
The more mass the more inertia Relationship between mass and inertia
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Newton's First Law
9.8 m/s/s acceleration due to gravity
The amount of air resistance is dependent on size and shape of the object Affect air resistance has on a falling body
There is no atmosphere to slow them down to different rates. Why do object on the moon fall at the same rate?
Force equals mass times acceleration Newton's second law equation
The acceleration of an object depends on the size of the force and the mass of the object. Newton's Second Law
As mass increases, the force of gravity pulling on the object increases proportionally. As a result the force of gravity divided by the object's mass will equal 9.8 m/s/s resulting in the same gravitational acceleration as all other objects. Affect of Newton's second law on falling objects
For every action force there is an equal and opposite reaction force Newton's Third Law
a property of a moving object that depends on the object's mass and velocity which affects how difficult it is to stop Momentum
anytime two or more objects interact momentum is exchanged, but the total amount of momentum stays the same Law of Conservation of Momentum
The explosion of the engine exerts a force on the launch pad. The launch pad exerts and equal and opposite force back up on the rocket ship. How does a rocket ship take off?
Newton's first law of motion states that once in motion, your inertia will keep you in motion. Why do you fly forward when the driver slams on the brakes?
Why is it harder to move a more massive object? The greater an object's mass, the more force is required for acceleration.

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.
