189 viewsThe force of the escaping gas from the fire extinguisher accelerates the person on the cart. If the gases exit the fire extinguisher to the right, WHY does the cart go to the left?Nov 09, 2006
|
|
119 viewsThe Van de Graff generator builds up a high static charge so that electric fields and charge transfer effects can easily be observed. Notice that the spark would prefer to jump to a point rather than a ball; hence, lightning rods attract lightning.Nov 09, 2006

|
114 viewsWhen in the atmosphere, the globe experiences a buoyancy force upward exerted by air. WHY does the globe seem to weigh more when the air is taken out of the bell jar?Nov 09, 2006
|
|
103 viewsThe air pockets in shaving cream will expand in a vacuum. So WHY does the shaving cream get bigger?Nov 09, 2006
|
|
110 viewsDue to the conservation of angular momentum, when the rotating person brings his arms closer to his body, he will rotate faster. WHY?Nov 09, 2006
|
|
105 viewsAt various points on the track, the car will have the same total energy, but it will be split into kinetic and potential energies dependent on its height and velocity. The higher the PE, the lower the KE and vice versa.Nov 09, 2006

89 viewsThis demo is a combination of explosive collisions and inelastic collisions. Each roller blader gains momentum with each toss AND catch of the pillow.Nov 09, 2006

97 viewsWhen a ping pong ball is placed in a funnel with the air blowing out, the ball won't fall out of the funnel. WHY NOT?Nov 09, 2006
|
|
110 viewsA small amount of water is heated in a soda can until steaming. The can is then quickly put in cool water, mouth side down. WHY does the can collapse? And, why did they need to heat water in the soda can to make this demonstration work?Nov 09, 2006

91 viewsIn this case, the momentum of the large ball is transferred to balls at the end. WHY does the last ball go out so far to the right?Nov 09, 2006

76 viewsThe falling target experiences the same vertical acceleration as a ball launched from a cannon aimed at it. If released at the same time WHY do they hit?Nov 09, 2006

161 viewsThe air pockets in jet-puffed marshmallows will expand in a vacuum. So, WHY does the marshmallow man get bigger as air is sucked out of the bell jar?Nov 09, 2006
|
|
113 viewsThe ball begins at the top to the right with "potential energy." WHY does it have enough energy to complete the loop without falling down?Nov 09, 2006

63 viewsIn all cases, the two carts stuck together after the collision will have a momentum that is equal to the combined momentum of the two carts before the collision. WHY?Nov 09, 2006

66 viewsLook at the wire extending from where the front legs of the horse should be to back behind the rear legs. Now notice that the toy horse is balanced on its rear legs. WHY? Nov 09, 2006

|
112 viewsOne ball, having only a gravitational force, will fall straight down. The other ball, having gravity and a horizontal force, will follow a parabola. Watch it in slow motion. WHY do they hit the surface at the same time?Nov 09, 2006

88 viewsOne cart is at rest when another cart of lower mass hits it. WHY does the cart on the right move away at a slower speed?Nov 09, 2006

128 viewsThere is a flexible membrane at the top of the cylinder. When the demonstrator puts his hand on the top of the cylinder, the "diver" sinks. When he takes his hand away, the diver rises to the surface. WHY?Nov 09, 2006
|
|
200 viewsThe bucket (and water contained therein) experiences centripetal acceleration when swung in a circle. WHY doesn't the demonstrator get wet? (or, WHY doesn't the water fall out of the bucket?)Nov 09, 2006

|
149 viewsOnly the center of mass of an object needs to be supported in order to support the object. WHY can you balance the bird so far back?Nov 09, 2006
