Types of Energy
What is the type of energy where the energy is in an object when it is in motion.
kinetic energy
What is the equation for Kinetic energy?
KE= 0.5mv²
What is the ultimate source of energy?
The Sun.
What is a type of energy that energy is stored due to the position of the object?
potential energy
What is the equation for potential energy?
PE=mgh
What is Earth's gravitational acceleration?
9.8 m/s²
What is the type of energy that is stored in something that can be stretched or compressed, for example a rubber band?
Elastic potential energy
In the equation, PE=mgh what does each letter stand for?
PE= Potential Energy
M= mass
G= Gravity at 9.8 m/s²
H= height
This states that energy can be changed (transformed) from one form to another but never created nor destroyed.
Law of conservation of energy.
what is this type of energy where energy is stored due to objects being above Earth's surface, for example a ball in the air?
Gravitational potential energy
in the equation, KE= 0.5mv², what does each symbol stand for?
KE= Kinetic energy
m= mass
v²= velocity or speed squared
Energy stored in atomic nuclei is known as what?
Nuclear energy.
What are the 6 major forms of energy?
Thermal, mechanical, electromagnetic, chemical, electrical, and nuclear.
When trying to solve problems with those equations, what is important to know about the relationship between PE and KE?
That PE=KE.
Thermal Energy.
