Nov 29 WS (basic relations, omega, linear and angular quantities, rotational inertia)
Rotational Practice Dec 2 04

• Tension in wire
• Circular wheel pulled over a step
• Pivoted rod angular acceleration
• Unwinding disc on a string (like a yo-yo)

• Tiddly-wink
• KE of a disc rolling w/o slipping
• Solid disc rolling down an incline
• Hoop rolling down an incline

• torque = r x F
• angular momentum
• bullet fired into a door
• soup can race - who wins?

• Lift wheel over a step
• stick pivoted, falling, find angular acceleration, etc.
• small disc dropped onto a large disc - find final angular velocity

PH 112 Review Problems 2003

• bar and cable and weights
• wheel lifted over a step
• grinding wheel slowed by a tangential force
• 2 blocks and a pulley
• one disc dropped on top of another
• two point charges
• find V due to two point charges
• find E due to two pt chargesw
• find PE of two point charges
• sketch a few E field lines
• a proton released from rest at a potential of 5000v . Given v, find the PE at that spot
• resistor changes shape - what's the new resistance
• series and parallel resistors, then ditto for capacitors
• given a block of metal and E fields near it how much charge is inside, charge/area on the sides?
• circuit problem with one current given, find other stuff

• Unwinding spool
• Child and merry-go-round
• Beam and box and cable
• Pulley and two masses
