What is friction?
An opposing force that causes drag.
Two objects moving against one another, creating heat.
What type of circuit is this?
Series Circuit
Does energy stay the same?
Yes or No?
No! It changes.
What are the two energies of force and motion?
Kinetic and Potential
Who invented the lightning rod?
Ben Franklin
What is mass?
Amount of matter something has
What type of circuit is this?
Parallel Circuit
What are three types of Energy?
Light, Sound, Thermal, Mechanical, Electrical are all types of energy.
I have a balloon filled with water and a balloon filled with air. Which would take more energy to move?
Balloon filled with water.
When pushing an object on a rug, I notice that the bottom of the object is warming up. What creates this?
Friction
What is speed?
How fast or slow an object is in relation to a certain amount of time.
Who is the man discovered electromagnetism and created the first electric generator?
Michael Faraday
A light uses two types of energy to power and stay lit. What are they?
Electrical and Radiant (Light)
What is motion?
How something moves.
The more mass in an object, the more energy or force will be needed to movie it.
What is a conductor?
What did Edison invent?
A longer-lasting lightbulb
What energy is needed to move around?
Mechanical
How does friction affect speed?
The rougher the surface, the harder it is to accelerate.
The smoother the surface, the easier it is to accelerate.
How can a circuit be turned on or off?
Creating an opening and closing it, or using a switch.
What is static electricity?
Electricity found and given off by an item that does not naturally create electrical energy.
What is a natural form of static electricity?
Name the three different transformations energy goes through in a flashlight.
Mechanical --> Electrical --> Radiant/Light
When objects of different sizes collide, how does the energy transfer?
Most of the energy will continue in the smaller one, sending it opposite of the larger object.
What object creates all of the different things in the Electromagnetic Spectrum?
The Sun
