Physics Why?

Physics -- Can you Explain what is happening in each picture?


#1: Arm Wrestling -- Which Law? -- What's happening here? -- What one word describes the action?	#2: Floating Balloons --Which Law? --What's happening here? --What concept describes the action?	#3: Cruising Car with Balloon Inside -- You're inside the car as it moves along at 45 miles per hour. You release a helium balloon and it floats to the ceiling. What happens next? -- Which of Newton's laws describes the action? -- What concept applies?


#4: Tennis Ball released by red-shirted boy at left edge of track -- What happens to the tennis ball? -- Why? -- Which law applies here? -- What two words describe the action?	#5: Man at Top of Roller Coaster Hill -- He's not moving very fast. Why not? --Why does he pick up speed as he goes down? -- Is his rate of acceleration 9.8 m/sec/sec? -- Before he starts his descent we say he has "stored energy." What do we call that?	#6: Left steel ball is pulled out and released -- What happens next? -- Why? -- Which law applies here? -- What concept applies?


#7: You're trapped in a elevator falling to the 1st floor. -- What one word governs your fate? -- What could you do to increase your chances of survival? -- Which of Newton's Laws applies here?	#8: Chair Ride at an Amusement Park -- Why are the riders slung out away from the central post? -- What concept applies here? -- What would happen if they weren't holding on? --Why doesn't gravity pull them down?	#9: You're sitting in an airplane cruising at 500 miles/hr at 30,000 ft. You flip a coin. -- What happens to the coin as it goes up in the air? -- Why? -- Which of Newton's laws applies here?


#10: You drop two cannon balls of different weights off the Leaning Tower of Pizza. -- Which one hits the ground first? -- Why? -- What is their acceleration rate?	#11: No brakes, steep hill. -- What concept governs your actions here? -- Which law applies? -- Wouldn't it be cool if your eyes could bug out like that?	#12: Car is cruising at 55 mph. Car stops suddenly. -- What happens to you? -- Why? -- Which law governs your actions? -- What concept applies?


#13: Trampoline. You're the one in the yellow shirt. -- You jump UP as high as you can go and then you come down on the trampoline and you bounce back up. Why? -- Which of Newton's Laws applies here? -- Why?	#14: Washing Machine full of water -- getting ready for the "spin cycle." -- How IS it that all that water goes away? -- Why don't the clothes go away too? -- What concept is at work here? -- Does gravity make the water go away?	#15: There's water in that cup flying around your head. -- Why doesn't the water in the cup get slung out? -- What concept is involved in it's STAYING in the cup? -- What concept governs the action pictured here?
