The forces acting on a flying ball are:
1. The frictional force exerted by air on the motion of the ball.
2. The gravitational force of the earth, of course.
The aerodynamic forces acting upon a glider in flight are lift and drag. Lift is generated by the airfoil shape of the wings and acts in an upward direction to support the weight of the glider. Drag opposes the motion of the glider and is caused by air resistance.
External forces that act on a hang glider include lift, gravity, drag, and thrust. Lift is created when the air flowing over the wings generates an upward force, supporting the weight of the hang glider. Gravity acts downward, pulling the hang glider towards the ground. Drag is the resistance encountered by the hang glider as it moves through the air, slowing it down. Thrust is the force generated by the pilot's movement or by a tow plane, providing forward motion for the hang glider.
The force of friction is not acting upon a ball that is thrown in the air. Friction is a force that opposes motion, but when a ball is thrown in the air, there is no surface contact for friction to act upon.
Mass is the property of matter on which gravity act upon.
The four forces that act on an airplane during flight are lift (upward force generated by the wings), weight (downward force due to gravity), thrust (forward force generated by the engines), and drag (rearward force resisting motion).

Yes. That's how the navigator of an airplane in flight is able to use a magnetic compass.
In flight, lift and weight act in opposition to each other, with lift generated by the wings counteracting the force of gravity acting on the aircraft. Similarly, thrust and drag act in opposition, with the engine propulsion providing thrust to overcome the drag force caused by air resistance on the aircraft.
In a torsion catapult, the main forces that act upon it are the torsional force applied to the twisted rope or spring when it is released, the gravitational force pulling the projectile downward, and air resistance opposing the motion of the projectile through the air. The torsional force causes the arm of the catapult to rotate and launch the projectile forward.
A unbalanced force must act upon it. ;)
An act comes into force as law once it has been approved by the appropriate legislative body, such as parliament or congress, and has been given the necessary legal assent by the relevant authority, such as the president or monarch. The act typically specifies its own commencement date or may come into force immediately upon receiving assent.
