Potential energy
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 found in
Every item/object
Kinetic energy is caused by
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 you meatball is placed on top of a mound of spaghetti, what type of energy does it have?
potential energy
What are some forms of energy besides kinetic and potential?
light, heat, sound, chemical energy, electricity, etc.
Potential energy is
Stored energy
Kinetic energy is
The energy of motion
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
The amount of kinetic energy is determined by its
Speed/velocity and mass
What happens to the kinetic energy of a glass when it falls and breaks?
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
