Kinetic and Potential Energy Stores Flashcards
1
Q
What always has a kinetic energy store?
A
Objects that are moving
2
Q
When is energy transferred to a kinetic energy store?
A
When the object speeds up
3
Q
When is energy transferred away from a kinetic energy store?
A
When the object slows down
4
Q
What does the Kinetic Energy Store dependant on?
A
mass and speed
5
Q
What is the equation for kinetic energy?
A
E = 1/2 mv2
Kinetic Energy = 1/2mass x speed2
6
Q
What is the equation for gravitational potential energy?
A
E = mgh
gpe = mass x gravatational filed strength x hieght
7
Q
What is the equation for Elastic Potential Energy?
A
E = 1/2Ke2
Elastic Potential Energy = 1/2 Spring constant x extension2
