P1.5 - KE And Elastic Potential Energy Flashcards
Elastic potential energy
-energy stored in an elastic object when work is does on the object
Formula for elastic potential energy
Elastic potential energy = 0.5 x spring constant x extension2
Hooke’s law principles
- doubling the force on a spring will double its extension
- the extension on a spring is proportional to the force applied until you reach the limit of proportionality
Limit of proportionality
Point where spring constant Connor return to its original length
Spring constant
- The ability of the spring bouncing back
- how much the spring can take
Hooke’s law formula
Force = spring constant x extension
Hooke’s law formula for spring constant
K = f divided by e
Formula for ke
Ke = mass x 0.5 x speed2
Ke formula for working out velocity
The square root of 2ke over mass
Ke formula for working out mass
2ke divided by speed2
Relationship between ke, mass, velocity
- doubling mass = doubles ke
- doubling velocity = quadruples ke
