What is Newtons?
State of matter with indefinite shape but definite volume.
What is a liquid?
This energy is the stored energy an object has because of its position or state.
What is potential energy?
These are inexhaustible and can be replaced in a short time by natural means.
What are renewable resources?
This is anything that occupies space and has mass.
What is matter?

What are melting and freezing points?
This type of energy can travel through a vacuum (a place with no matter).
What is light energy?
This type of power has cells absorbs the sun‘s light and covert it into energy.
What is solar power?
This is a force causing displacmental on an object.
What is work?
