Energy Flashcards
What is energy measured in
Joules
When is work done?
On object when a force is exerted on object and moves I’m direction in which force is applied
How is work done
Lifted vertically at constant speed
Pushed horizontally with constant applied and friction force.
Pushed horizontally with constant applied smooth surface
What is kinetic energy
Possesses due to motion
What is potential energy
Stored
By position of object or particles which react with each other
Ethan is the energy transformation of a object dropped from distance?
Gravitational to kinetic
What is the energy transformation of a spring
Elastic potential energy to kinetic energy
