- 1SHMsimple harmonic motion-
movement back and forth in same amount of time (periodic)
ie. spring system - 2Force equation for springsF= -kx
- 3why is there a minus sign in the forrce equation?because the restoring force takes it back in the opp direction
- 4are force and acceleration c conconstant in a spring?Nope. Neither one of them are.
- 5label what f and a are at each pointx=-1 (-A): f=max, a=max, all PE, v=0
x=0: f=0, a=0, all KE, 0 PE, v= fastest
x=1 (A): f=max, a=max, all PE, 0 KE, v=0 - 6how long is a full cyclefull to and fro motion
=4A - 7Frequencynumber of cycles per second
- 8periodtime to complete one cycle
