Very Happy Physics Students at Custer Park  March 6, 2015

                     Right BACK at ya!

Hang on! 
Lets take this thing for a spin.

Hey, where is Britta?   
Oh there she is!

Phew!  THAT was close!
Everybody still happy!

Playground Physics Lab

Meet at Custer Park       Don't forget permission slips and medical forms

SW 21st and Capital Highway 

815 am Friday period 5   March 6

•Dress warm, grass will be dewy,  gloves? for cold metal

•bring supplies, phone timer, calculator, lab notebook etc.

Wilson AP Physics :    PLAYGROUND PHYSICS

OBJECTIVES:

To make accurate measurements of rotational motion in a neighborhood park

Specifically :

SEESAW

1.     Determine the mass of a seesaw.

2.     ?

Merry-go round

1.     Determine the Rotational Inertia, I and the Mass of the spinning disk

Measure the change in angular velocity ( angular acceleration) caused by several tangential forces applied to the edge of the spinning disk

2.     Determine Frictional torque and force on the axle of the spinning disk

Measure the angular acceleration caused by that friction
