ch.4 acceleration

accelerated motion in a straight line

QuestionAnswer
acceleration rate of change in the speed of an object
delta "the change in"
constant acceleration speed that changes by the same amount every second
uniform acceleration another word for constant acceleration
slope rise to run.rise:amount the speed changesrun:amount the time changes
term piece of an equation
initial speed first term of the formula is the speed the object starts with
free fall moving under the influence of gravity only
acceleration due to gravity symbol:(g)equation:9.8m/sec2
time of flight object takes the same time going up as it takes coming down
friction when air resists the motion of objects moving through it
air resistance when small objects at low speeds is neglected by air
terminal speed maximum speed at which an object falls when limited by air friction
acceleration equation acceleration=change in speed/change in time=meters per second/second=meters/second X second=m/sec2

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.
