Power, Work, Energy Flashcards
(18 cards)
The product of displacement and the force in the direction an object moves.
Work
What is the Formula of Work
Work = Force x Displacement
What is the definition of Energy?
The ability or capacity to do work/
What are the 2 types of Energy
Kinetic And Potential Energy
Energy that is stored due to position or shape. it is stored energy
Potential Energy
There are 2 types of Potential Energy
- Gravitational Potential Energy (GPE)
2) Elastic Potential Energy
Potential Energy that depends upon an objects height above a reference point
Gravitational Potential Energy (GPE
What is the formula of Gravitational Potential Energy
PE = mgh
The higher the object, the more potential energy
Height
The greater the mass of the object, the more potential energy it has.
MAss
Potential energy depends on both>
mass and height
The potential energy of an object that is stretched or compressed.
Elastic Potential Energy (EPE)
When stored energy begins to move, the object now transfers from potential energy into kinetic energy.
potential Energy Converted to Kinetic Energy
The energy an object has due to its motion
Kinetic Energy
Formula of Kinetic Energy
KE = 1/2 mv^2
The faster the object moves, the more kinetic energy it has.
Velocity/Speed
the greater the mass of a moving object, the more kinetic energy it has.
Mass
Kinetic energy depends on both
mass and velocity.
