Types of Energy
Energy of Motion
What is Kinetic Energy?
Running through a sprinkler in the summer
Types of Potential Energy
What are gravitational, elastic, and chemical?
the formula for solving the amount of kinetic energy an object has
What is KE = 0.5*m*v2?
The Definition of Energy
What is ability to do work?
Stored Energy
What is Potential Energy?
a sprinter in the ready position on the blocks
What is an example of potential energy?
A pendulum at the top of its arc just before it is released
What is gravitational potential energy?
The formula for solving how much gravitational potential energy an object has
What is PE = m*g*h?
Factors that affect the amount of kinetic energy an object has
What are mass and velocity?
(I would also take mass and speed)
Energy due to elevation (height)
What is Gravitational Potential Energy?
a skateboarder at the top of the ramp
What is an example of potential energy?
A stretched rubber band
What is an example of elastic potential energy?
the amount of KE in a 10 kg object travelling at a constant speed of 5 m/s
What is 125 J?
Factors that affect the amount of gravitational potential energy an object has
What are mass and elevation?
Energy due to stretch or compression
What is Elastic Potential Energy?
A skateboarder at the bottom of the ramp
What is an example of kinetic energy?
An apple before it is eaten
What is an example of chemical potential energy?
The amount of KE in an 8 kg object travelling at a constant speed of 9 m/s
What is 324 J?
The relationship between kinetic energy and gravitational energy
What is an inverse relationship, when KE decreases the PE increases and vice versa?
Energy stored in the bonds between atoms/molecules
What is Chemical Potential Energy?
a skateboarder on their way down the ramp before they reach the bottom
What is an example of kinetic energy AND potential energy?
A bouncy ball bouncing on the floor
What is an example of elastic potential energy, gravitational potential energy, and kinetic energy?
The amount of gravitational potential energy in a 15 kg object held 20 meters above the ground, assuming gravity is 9.8 m/s2
What is 2940 J?
The definition of the Law of Conservation of Energy
What is energy can be not be created or destroyed, only transformed into other types of energy?
