Heat Transfer
What is an example of Convection Heating?
Microwave, ovens, radiators, and air conditioners.
What is kinetic energy?
Kinetic energy is the energy of a moving object.
What is speed?
How fast or slow something is moving
What is energy?
Energy is the ability to do work or cause change.
What happens when there is no motion?
An object is resting (potential energy)
Define Conduction
Conduction is the transfer of heat through a solid material by direct contact of particles.
What is potential energy?
Potential energy is stored energy in an object.
What is gravity?
Gravity is a force that pulls objects toward the Earth.
Name two main types of energy.
Potential & Kinetic Energy
How does the heat from the sun reach earth?
Through Electromagnetic Heat Waves
Convection transfers heat through the movement of fluid particles; warm fluid rises and cool fluid sinks, forming a convection current.
What is motion?
Change in a object's position
What is volume or mass?
Volume is the amount of space something takes up.
Mass is the amount of matter in an object.
What kind of energy is stored in a stretched rubber band?
Potential Energy
Which of the three heat transfer methods requires direct contact between substances?
Conduction requires direct contact between substances.
What is radiation heat transfer?
Heat energy transmitted in the form of electromagnetic waves. (No contact)
When you lift a book up high, what kind of energy does it have?
Potential Energy
Bike going down the hill - what part of the hill has the EQUAL potential & kinetic energy? (At the top, in the middle of the hill at the bottom)
Middle of the hill
Hydropower, wind and solar energy
Can energy be created or destroyed? If not, what can energy do?
No, energy can only change from one form to another.
They start vibrating more creating friction.
Bike going down the hill - what part of the hill has the most kinetic energy? (At the top, in the middle of the hill at the bottom)
At the bottom of the hill
What is the definition of Physics
The scientific study of matter, its motion, and energy
What kind of energy does a battery store?
Chemical Energy
Bike going down the hill - what part of the hill has the most potential energy? (At the top, in the middle of the hill at the bottom)
