Energy
what is energy
the ability to do work
what is friction
a force that opposes motion
what is bouyancy
The force exerted by a fluid on an object immersed in the fluid
What is a collision
it is an intreaction between to objects
what is weight
The result of gravity pulling on an object
what is sound energy
energy carried by sound waves
what is air resistance
a type of drag
what is bouyant force equal to
the weight of the displaced fluid
Do most collision involve at least one moving object
Yes
What is weight mesured in
what is light energy
energy carried by light waves
what is drag
air friction
the greater the bouyant force the more fluid displaced or the dencer the fluid
the more fluid displaced
what is kinetic energy most often tranformed into
thermal energy and sound energy
is weight a force
Yes
what is thermal energy
energy associated with the temperature of an object
dose a smooth surface exert less or more friction
less friction
What direction does bouyant force act on an object that is immersed in the fluid?
Upward on the immersed object
Does energy get transferd or tranformed or both
Both
does an objct mass change on other planets
NO!
what is nuclear energy
energy stored within the nucleus
would gravel create a lot of friction or a little
A lot
If bouyant equal to or greater than the imersed object will it float or sink
Float
What does energy is conserved during a collision
The total energy of the system stays the same
Is weight the same as mass
NO!
