Mechanics: LInear Mo

LInear motion and force and momentum

TermDefinition
Zero error The amount you need to add or subtract to make your starting point zero.
Vector A quantity that has magnitude and direction
Scalar A quantity that has magnitude only and has no direction in space
Displacement (s) the distance moved in a particular direction. Unit m
Velocity (u or v) the rate of change of displacement with time. Unit m/s
Constant Velocity If an object doesn't speed up, slow down or change direction
Acceleration (a) the rate of change of velocity with time. Unit m/s squared
A Force Anything that makes an object move or change velocity
Momentum (p) the momentum of a body is the product of its mass and velocity
Newton's First Law All bodies will remain at rest or at constant velocity unless an external unbalanced force acts on them
Newton's Second Law The rate of change of a bodies momentum is proportional to the net force applied and will act in the direction of the force
Newton's Third Law Every action has an opposite but equal reaction
The Principle of Conservation of Momentum The total momentum of a system before an interaction is equal to the total momentum of the system after an interaction, so long as no external force acts on it
Newton's Law of Universal Gravitation Every mass in the universe attracts every other mass with a force, along the line of their centres, that is proportional to the product of their masses and inversely proportional to the square of the distance between them

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.
