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?
