Temperature and Volume for a Gas

# This happens when you don't properly vent a storage tank

"This happens when you don't properly vent a sealed storage tank before emptying it.
Hot gas/air in the sealed container is left to cool. The air pressure difference inside is so great that the structure is compromised. "

B) Kinetic Energy - the energy an object possesses due to its' motion

Newton mistakenly believed that the
kinetic energy of a moving body was
directly related to its velocity.

KE,V have a ....

Direct Square Relationship

Equation

 KE = (˝)mv2

Relationships

KE/m

Direct

 KE = (˝)mv2

KE/v?

Direct Square

 Ex 1) A 60.0-kg runner has 1920 joules of kinetic energy. What speed is her speed?

Ex) A 60.0-kg runner has 1920 joules of kinetic energy.

What is her speed ?

 KE = (˝)mv2

m = 60.0 kg
KE = 1920 J

V = ?

1920 J=(1/2)60.0kgV2

1920 J = 30V2

64.0 = V2

V = 8.00 m/s

Summary  W, K E, PE

 K.E. - equivalent to work needed to get an object to a certain  speed or to stop it.

 P.E. - Equivalent to work needed to get an object to where it is or into its present condition.( spring)

W = Fd = ΔPE

If W = 40 J

Then ...

ΔPE = 40 J
