# PHYS 1500 Chapter 3

equilibrium experiencing zero net force
equilibrium position natural position of a spring when it's not being compressed
stable equilibrium state of the spring after it has been compressed
restoring force causes a spring to return to its equilibrium length once no more force is being exerted on it.
hooke's law restoring force= -spring constant * distortion F=-kx
elastic limit how far a spring or an object can stretch before becoming permanently damaged.
elastic potential energy energy stored in a spring when compressed
calibration comparing a local device to a generally accepted standard
center of percussion point on a baseball bat that does not experience acceleration
vibrational node part of the bat that does not vibrate when it strikes the ball
elastic collisions theoretical collision in which all collision energy is returned as rebound energy
inelastic collisions some collision energy fails to become rebound energy
uniform circular motion an object has the urge to move in a straight line but in pulled into circular motion
centripetal acceleration acceleration toward the center of a circle
centripetal force force that pushes an object toward the center of a circle
feeling of acceleration feeling that the body is moving in the opposite direction of acceleration
apparent weight the feeling of weight changes during acceleration
a= v^2/r or w^2*r

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.
