What is kinetic energy?
Kinetic energy is energy of motion.
100
What is potential energy?
Stored energy
100
what is energy?
the ability to work
100
What type of energy is produced and wasted during most energy transformations?
thermal
100
What is newtons first law?
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
200
Can kinetic energy be transferred?
Yes.
200
What is an example of potential energy?
Anything answer that includes someone of something at rest (not moving).
200
what energy is generated by moving electrons?
electrical energy
200
In what state is chemical energy always in?
potential energy
200
What is newtons second law?
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.

What is an example of kinetic energy?
Any answer including someone or something in motion.

Where does a car on a hill have the most potential energy?
Top of the hill.
300
What type of energy do we get from the rays of the sun?
radiant energy
300
What energy transformation takes place when something burns?
chemical to thermal
300
What is newtons third law?
All forces in the universe occur in equal but oppositely directed pairs. There are no isolated forces; for every external force that acts on an object there is a force of equal magnitude but opposite direction which acts back on the object which exerted that external force.
