P1.5 Kinetic energy and elastic energy stores Flashcards
1
Q
What is the equation for kinetic energy?
A
E(k) = 1/2 x mass in kg x speed^2 or v^2 in metres per second
2
Q
What is Hooke’s law?
A
F = ke where Force is directly proportional to extension
3
Q
What is k?
A
The spring constant
4
Q
What is the equation for elastic potential energy?
A
E(e) = 1/2 x spring constant, k x extension ^2 in metres
