• Using a flashlight

Multiple Choice

What is energy that is set in motion?

• Kinetic

• Potential

Multiple Choice

What is the main difference between Matter and Mass?

• Matter is anything that takes up space, but mass is the amount that space has.

• They are the same thing

Multiple Choice

Density is best explained in the foruma p=m/v. What does the m and v stand for?

• Mass over volume

• Volume over Mass

• Velocity over Speed

• Distance over time

Conduction

• Conduction is the transfer of energy in the form of heat or electricity from atom to atom.

  
  

• It occurs in solids, liquids and gases.

• It occurs in two main forms: heat and electricity.

Convection

• The transfer of energy such as a heat through air or water.

• Heat transfer through movements of particles.

• The three processes of heat transfer is conduction, convection and radiation.

Conduction vs Convection. What is the main difference?

Convection- the heat is transferred through a mass flow of material but conduction heat is transferred through collisions of particles that make up material.

Radiation

Energy that comes from a source and travels through space and may be able to go into materials.
