Potential and Kinetic Energy
The top of a rollercoaster is where you will find the greatest amount of this type of energy.
What is potential/gravitational potential energy?
The color we see when all wavelengths of light are reflected.
What is white?
This type of energy is caused by the movement of electrons.
What is electricity?
These 2 factors affect the gravitational force between objects.
What is mass and distance
A catapult is this type of simple machine
What is a lever
Between a steel and ceramic marble, this one will have more kinetic energy when rolled down a track.
What is a steel marble?
This color would increase the absorption of photons on a solar panel.
What is black?
This type of energy can be transferred from radiant energy to thermal to mechanical to electrical energy.
What is solar?
This factor increases the inertia of an object.
What is mass
The speed of an object in a particular direction.
What is velocity
The "bottom" of the pendulum swing is where you find the most of this type of energy.
What is kinetic energy?
Using less energy to perform the same task to reduce energy waste.
What is energy efficiency?
A benefit of wind energy
What is...no greenhouse gases
..No air or water pollution
.."Fuel" is free
..relatively inexpensive
These are all 3 types of non-contact forces.
What is gravitational, electrostatic, and magnetic
The pivot point of a lever
This factor significantly changes the speed of a pendulum.
What is the length of the pole?
This type of energy transfer is part of the greenhouse effect
What is radiation?
This type of energy came from microscopic and other ocean organisms millions of years ago.
What are fossil fuels
The difference between mass and weight
What is weight is a force due to gravity and mass is the matter/molecules that make up an object
A simple machine that operates in an elevator
What is a pulley
This law states that energy cannot be created or destroyed, but can be transferred between objects and converted from one type of energy to another.
What is the Law of Conservation?
Infrared photons are trapped in our atmosphere and re-radiated back to Earth mostly because of this.
What is a layer of Carbon Dioxide from the burning of fossil fuels?
*(6M metric tons in 2020) 79% of all greenhouse gas emissions*
The rate of electron flow
What is current
Any change of velocity: this can be either speeding up or slowing down
What is acceleration
This states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
What is Newton's Third Law
