During the Throw:
* Force Applied by Your Hand: This is the initial force that sets the ball in motion. It's a contact force that acts in the direction you throw.
* Air Resistance (Drag): This force opposes the ball's motion, acting in the opposite direction to its velocity. It increases as the ball's speed increases.
* Gravity: Acts downwards on the ball throughout its flight, pulling it towards the Earth.
After the Throw:
* Air Resistance (Drag): Continues to oppose the ball's motion.
* Gravity: Still pulling the ball downwards, causing it to follow a curved trajectory.
Other Forces (Less Significant):
* Buoyancy: A very small force that acts upwards due to the ball displacing air. It's usually negligible.
* Magnus Force: A force that can arise if the ball spins. It acts perpendicular to the direction of spin and can contribute to curves or wobbles.
Key Points:
* Net Force: The combination of all these forces determines the ball's overall motion.
* Trajectory: The path of the ball is a result of the interplay between gravity and air resistance.
* Motion: The ball will continue in motion until it is acted upon by another force (like the ground when it lands).
