If a juggler moves a pin with his hand and gives what kind of energy to the pin?
kinetic energy
How can you tell that the kinetic energy is decreasing as the juggler pin rises?
The fact that the juggler's pin rises to a point and then falls back down is an indication that the kinetic energy decreases as the pin rises. At the highest point reached by the pin, its motion stops and it hangs in the air for a short moment, at which time kinetic energy is zero, and potential energy is at its maximum.
Does the mass of the spinning tops affect how long a spinning top spins?
Yes it affects it. Imagine a heavy top and a light top spinning at the same rate. There are two things which are slowing them down - friction of the bottom pin on the supporting surface and the viscosity of the air, as it is stirred by the rotating surface it covers. The heavier top has more energy than the light top. Assuming that the two are the same size and have the same shape and surface texture, then the rate of loss of energy to the air is the same for both. It is likely that the friction at the pin will be greater for the heavy top and so the energy loss rate there will be greater. Therefore, the overall loss-rate cannot be decided. The heavy top may have a sticky pin and lose its extra energy quickly, collapsing before the light pin. However, it seems to me that the loss of energy to the air is considerably more than the friction loss at the pin and therefore the heavier top will be losing energy at a rate not much greater than the light top. The heavier top can start with a lot more energy than the light one, and so I vote for the heavy top spinning for longer.
What energy transformations occur when a gun is shot?
•Kinetic in the firing pin - chemical when it hits the primer- turns back into kinetic(both ways), light, heat, and sound energy - hits the target kinetic, light and sound.
Why is it easier to push a sharp pin into a board rather then a blunt pin?
Pressure is inversely proportional to area. A sharp pin has lesser area compared to a blunt pin. Therefore we require lesser pressure to push the pin with lesser area.Hence it's easier to push a sharp pin which has lesser area.

Why does the steering wheel turn but the wheels don't?
If the steering wheel turns, but the wheels do not on an automobile, the steering pin is defective. The steering pin connects the wheels to the action of the steering wheel. An automobile that has a steering pin malfunction should not be driven.

What is the lynch pin theory?
A lynch pin in its true definition is a pin inserted in the end of an axle to keep a wheel from coming off. Lynch pin theory is by making a small seemingly insignificant change (the lynch pin) it will create a much larger event. Just like a lynch pin on an axle, if removed, the wheel will eventually come off and whatever the wheel is holding up will crash.
My steering wheel on 1997 olds aurora is loose help?
There is a pin that goes in the side of the steering wheel. Take off the sterring wheel and cover. You should see a hole and the pin goes in there

Why should a new cotter pin be used when assembling a wheel bearing?
A new cotter pin should be used that way the cotter pin keep front wheel and hub from coming off, possibly causing a serious accident.
