P1.5 Kinetic And Elastic Flashcards
1
Q
What is kinetic energy
A
The energy an object has due to its motion
2
Q
How to work out kimetic energy
A
Ek = 1/2 x mass x velocity ^2
3
Q
What is elastic energy
A
The store in an object when stretched or compressed
4
Q
How to work out Elastic potential
A
Ee = 1/2 x k x e ^2
K = spring constant
e = extention
5
Q
Whats hookes law
A
The extension of the spring is directly proportional to the force applied provided it’s limit of proportionality is not exceeded
6
Q
How to calculate Ke lost
A
Final Ke - initial Ke
7
Q
What is direct current
A
electrical current which flows consistently in one direction
