Potential Energy
What type of energy is stored in an object due to its position?
What is potential energy?
What is kinetic energy
The energy of an object in motion
Define gravitational potential energy (GPE)?
The energy an object posesses due to its height above the ground
Give an example of a situation where potential energy is present.
What is a bunny at the top of a hill
How does speed affect kinetic energy?
Kinetic energy increases with speed
Energy stored in objects that can be stretched or compressed
What factors can affect gravitational potential energy?
The height of the object and its mass
What happens to KE of an object if its mass doubles
It doubles because KE is proportional to mass
Define work
Work is done when a force moves an object a distance
Explain how potential energy can be transformed into kinetic energy
When an object falls, its potential energy converts to kinetic energy as it speeds up
If a bunny is moving faster, what can you say about its kinetic energy compared to when it was moving slower
Its kinetic energy is greater when the bunny moves faster
What is the law of conservation of energy?
Energy cannot be created nor destroyed, only transformed
Compare elastic potential energy with gravitational potential energy
"EPE" is stored in stretched or compressed objects while GPE depends on an objects height above the ground
What is formula for KE?
KE=1/2mv2
Explain the relationship between energy and motion
Energy is required to cause motion and moving object possess kinetic energy
