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 _____________
