1
Q
Types of collisions
A
Elastic - p and KE conserved
Inelastic - p conserved
Perfectly inelastic - type of inelastic, objects stick together
2
Q
Adiabatic process
A
No heat transfer
3
Q
Open vs closed vs isolated system
A
Open - energy and matter in/out
Closed - energy in/out
Isolated - none
4
Q
Archimedes principle
A
Buoyant force is equal to the weight of fluid displaced by the object
5
Q
Venturi effect
A
Low pressure in high velocity regions
Due to bernouilli effect
6
Q
Doppler effect equation
A
Fo/Fs = (v +/- vo)/(v -/+ vs)
Top for towards
Bottom for away
7
Q
Converging lens
A
Beyond C - between F and C
Between F and C - beyond C
Between F and lens - virtual, beyond C same side upright
8
Q
Diverging lens
A
Always virtual
As object approaches lens, image grows larger and moves from focus to lens
