Energy and graphs Flashcards
1
Q
What does the resotirng force cause in terms of energy?
A
- exchange EP and EK
2
Q
WHat are the different PE for spring and pemdulum
A
- spring
- elastic
- pendulum
- GPE
3
Q
What happens as the object moves toward the midpoint?
A
- the restoring force does work on the object
- transfers EP to EK
4
Q
When is the EK max
A
at zero displacement
5
Q
What is mechnaical energy? How does it change?
A
- sum of PE and KE is mechanical energy
- stays constnat
- as long as the motion isn’t damped
6
Q
Describe the graph for displacement, velocity and acceleration
A
7
Q
Why are freq and T independant on amplitude
A
beleedat
