newtons first law ,inertia,and motion

termdefinition
Distance how far you have travelled between two positions.It is always positive.It is a scalar quantity
Displacement change in postion . It is the straight line distance between your starting postion and ending postion , It is equal to final postion . It can be positive or negitive . It is a vector quantity
scalar quantity that only requires magnitutde (how big)
vector quantitiy that requires both magnittude and directions
speed how fast something is moving . It is equal to distance divided by time . It is a scalar quantity
velocity rate at which positions changes .It is equal to displacement divided by time . It is a vector
Newtons First Law An object at rest will stay at rest an object in motion will stay in motion with the same speed and in the same directionand in the same direction unless acted upon by a unbalenced force.
Mass a measure of the amount of matter an object contains. Also a measure of the amount of interia a object has

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.
