What does PE stand for
What is Potential Energy
What does KE stand for
Kinetic energy
When you knock over a line of dominoes, what happens to the kinetic energy?
It gets transferred from one domino to the next.
Energy is the ability to
do work or cause a change.
Potential energy is
Stored energy
Kinetic energy is
The energy of motion
If you drop a bowling ball off of a roof, where does it have the most kinetic energy?
Just before it hits the ground.
What is the law of conservation of energy?
Energy cannot be created or destroyed, but it can be transferred or change forms.
The more mass the more
Potential energy
The faster an item moves
The more kinetic energy it has
If your meatball is placed on top of a mound of spaghetti, what type of energy does it have?
potential energy
What has energy?
Everything!
What are 4 forms of potential energy?
Gravitational, elastic, chemical, magnetic.
What are 4 forms of kinetic energy?
thermal, sound, electric, electromagnetic.
As a roller coaster moves down a hill, what happens to its potential energy?
It changes into kinetic energy?
What has the greatest effect on an object's kinetic energy?
It's speed
The amount of potential energy is determined by its
Height and mass
These two things determine the amount of Kinetic Energy.
Speed/velocity and mass
If a glass when it falls and breaks, what are two energy transformations or transfers that will occur?
Some of it transfers into the floor and air. Some of it becomes sound. Some is carried by the pieces in different directions.
What is the formula for calculating kinetic energy?
KE = 1/2 x mass x velocity2
