1. Gravity: This is the force that pulls the body downwards towards the center of the Earth. It acts constantly throughout the entire motion, regardless of the body's direction.
2. Air Resistance: This force opposes the motion of the body through the air. It acts in the opposite direction to the body's velocity, and its magnitude depends on factors like the body's speed, shape, and the density of the air.
Note: In some situations, other forces may be present, such as:
* Thrust: If the body is propelled by a rocket engine or similar system.
* Buoyancy: If the body is thrown in a fluid (like water), it will experience an upward force due to buoyancy.
However, in the most basic scenario of throwing a body upward, the two dominant forces are gravity and air resistance.
