Schlooders Mcgoovers
Materials 1” PVC pipe Three 45 g steel balls, One 67 g steel
ball Funnel Plastic cup, Bottom of Plastic Bottel 2 pulleys and string Wood Mousetrap Dominos Ipod and speaker
Step One• Conservation Of Energy
• ½ mv2 + mgh = ½ mv2
2 + mgh2
• Mass – 45 g
• PVC pipe
Step Two• Projectile Motion• y – yo = (x – x0) tanϴ- 2/gvo
2 (1 + tan2ϴ)(x – x0)2
• Torque• τ = r x F
• Plastic Cup, Funnel, Pulley with string
Step Three• Center Of Mass• M1R1 + M2R2… MnRn M1+ M2 ... Mn
• 67 g piece of wood
• One 67 g steel ball
• One 45 g steel ball
Step Four• Torque • τ = r x F
•Conservation of energy• ½ mv2 + mgh = ½ mv2
2 + mgh2
• Bottom of plastic bottle, pulley, PVC pipe
Step Five• Elastic Collisions• M1V1 + M2V2 = M1V1’ + M2V2’
V1 – V2 = -(V1’ – V2’)
• Dominos
Step Six• Force of Mousetrap
• Hooke’s Law F = kx
• Unplugs Ipod turning off song
