The spinning thing on top of a helicopter is called a 'rotor'. They are also on the end of boats to propel them through water.

What direction does a helicopter's rotors spin?

Depending on the make of the helicopter, some will rotate clockwise and others will rotate counter-clockwise. However, the main rotor and tail rotor will spin opposite of each other. If the tail rotor spins clockwise, the main rotor will spin counter-clockwise. The main rotor also spins for lift, the tail rotor for control.


Why is it necessary to have the tail rotor on the helicopter that spins perpendicular to the spin of the main rotor?

"For every action there is an opposite and equal reaction." For the helicopter to make the blade move in one direction, the blade will try to make the helicopter move in the opposite direction. Since the blade tries to make the helicopter spin, something is needed to keep the helicopter from spinning. So the manufacturer puts a tail rotor on the helicopter.


What energy is spinning tops?

Spinning tops possess kinetic energy, which is the energy of motion due to their spinning motion. This energy is generated as the top rotates on its axis, and the faster the top spins, the more kinetic energy it possesses.


Is spinning top an example of non periodic motion?

No, a spinning top is an example of periodic motion because it follows a repeated pattern or cycle as it spins around its axis.


How does a helicopter get its lifting force?

A helicopter gets its lifting force from the rotation of its main rotor blades. As the rotor blades spin, they create a pressure difference between the top and bottom surfaces, generating lift that enables the helicopter to become airborne. The angle of the rotor blades can be adjusted to control the amount of lift produced.

Why does not the body of the helicopter rotate in the opposite direction?

It has another rotor on the tail that spins vertically and counteracts the effects of the rotor on the top. Still, a helicopter is difficult to keep balanced and helicopter pilots are very talented people!
