Types of Energy
Give an example of kinetic energy
Name a renewable energy source:
The sun, the ocean, wind, ect.
What is matter?
Matter is anything that has mass and takes up space (volume)
Name one type of change in matter?
Melt, Boil, Freeze, etc.
What is a force?
A force is a push or pull acting upon an object resulting from its interaction with another object.
Give an example of luminous energy:
Light, torch, the sun.
Name a non-renewable energy source:
Ex. Oil, wood, coal, etc.
What are the three origins of matter in nature?
What is the difference between physical change and chemical change?
chemical changes produce new substances with new properties, while physical changes do not.
Name two action-at-a-distance forces.
Magnetism, Gravity
What is energy?
The capacity to do work, act upon matter, or cause change
Explain the difference between renewable and non-renewable energy.
Non-renewable = finite
Is a desk natural or manmade?
Manmade.
What are the 2 types of changes in matter?
Physical changes and chemical changes
Name the four forces involved in flight.
The four forces involved in flight are lift, weight (or gravity), thrust, and drag.
Name 3 types of energies
(examples: thermal, electrical, kinetic, chemical, sound, etc.)
What's an example of a machine that generates renewable energy?
Windmills, solar panels, Hydro-dams etc.
Manmade: Plastic, glass, paper
Give an example of a physical change and a chemical change.
Physical: Ice melting, water evaporating
Chemical: Iron rusting/ a cake being baked
Which force has these four principles: weight, lift, thrust, and drag?
Aerodynamic Force
What is the difference between kinetic and potential energy?
Kinetic energy is the energy of motion, determined by an object’s speed and mass (e.g., a moving car), while potential energy is stored energy based on an object's position or configuration (ie. a rock held in the air)
Where does your power for your home come from?
A power plant/ a nuclear power plant
Explain why plastic is man-made and wood is natural?
Plastic requires a process of creation and wood is naturally foud.
Explain how burning wood is a chemical change.
Burning wood is a chemical change because it involves combustion, transforming wood, oxygen, and heat into entirely new substances: ash, carbon dioxide, and water vapor.
Give an example of contact force AND non-contact force.
Kicking a football. and using a magnet.
