What forces are acting on a helicopter when it is still?
When a helicopter is hovering (aka "still") it has the force of gravity pushing "down" toward the Earth and the force of "lift" of the spinning rotor blade(s) pushing against the surrounding air. When the gravitational force is equal to the force of lift the helicopter hovers on the vertical axis.
How much force exert when lifting an object?
a force of depend on mass
What is an example of muscular force?

What science concepts are involved in helicopter flight?
lift and the down force of air
Why don't helicopters spin in circles?
The back rotor of the helicopter counters the force applied to the body of the helicopter by the main rotor by applying thrust in the same direction as the main rotor. The force from the main rotor is applied in the opposite direction the main rotor is spinning. So say the force the main rotor was exerting on the body of the helicopter was causing the tail to move left then the back rotor would be designed to apply an equal force pushing the tail right to keep it from spinning. If the back rotor of a helicopter malfunctioned it would begin to spin.

Do the rear blades of a helicopter lift the helicopter?
NO, the main rotor does the lifting and the small rear propeller is used to stop it spinning around and help with steering it.
How does the helicopter get its lifting force?
the helicopter pushes forward when the pilot pushes the cyclic control forward. that rotates the blades forward . while pushing forward on the cyclic, the pilot must also pull up on the collective control. that will add pitch to the blades, thrusting the helicopter forward.
