PHYS 1500 Chapter 3
| Question | Answer |
|---|---|
| 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 |
