Chapter 1 What is Energy?

energy

Ability to do work

form

Energy can transform from one _______ to another.

law of conservation of energy

Energy cannot be created or destroyed

kinetic energy

Energy of motion

electrical energy

Energy resulting in the movement of charged particles

nuclear energy

Energy stored in the nucleus of an atom

sound energy

Energy that creates noise through vibrations

thermal energy

Heat energy - fast the particles are moving the hotter the object is

add its kinetic and potential energies

How can you find an abject mechanical energy?

at its highest point before it falls back down

If I shoot a basketball, at what point does the basketball have the greatest potential energy?

potential energy

Stored energy and object has which can change based on its position or shape

energy transformation

Takes place when energy changes from one form into another form.

chemical energy

The energy in food and fuel and cells

mass and speed

These two things have effect on an objects kinetic energy..

pizza

This is an example of chemical energy.....

rubber band being stretched

This is an example of elastic potential energy..

A bowling ball being dropped off the top of a building

This is an example of gravitational potential energy...

dancing

This is an example of kinetic energy....

A ball sitting at the top of a hill

This is an example of potential energy....

False

True or False. The Law of Conservation of Energy states energy CAN be created or destroyed.

True

True or False. The kinetic energy is GREATEST at the BOTTOM of the hill, swing, etc.

friction

What causes a pendulum to finally stop swinging?

mechanical

When you ride your bike, the chemical energy is converted not only into kinetic but also into ___________________ energy.

Yes

Yes or No. A lamp starts with electrical energy, moves to light energy, then becomes heat energy.

No

Yes or No. Potential energy is when an object is in motion.

electromagnetic energy

energy that travels in waves which vary in length

mechanical energy

the amount of work an object can do because of the object's kinetic and potential energies

power

the rate at which energy is transferred is called _____________
