The upward motion of a thrown ball is affected by three main factors: initial velocity, air resistance, and gravity. The initial velocity determines how fast the ball is thrown, air resistance slows down the ball's upward motion, and gravity pulls the ball back down.
The height of the throw does not affect the upward motion of the ball. The ball will always follow the same trajectory regardless of the height it is thrown from. However, a higher initial height will result in the ball reaching a higher maximum height before falling back down.
The ball's velocity decreases as it travels upward due to the influence of gravity and air resistance. This causes the ball to slow down until it reaches its maximum height, at which point it stops moving momentarily before falling back down.
The mass of the ball does not affect its upward motion. According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass. Since the force of gravity is the same for all objects, the mass of the ball does not affect its acceleration and therefore does not affect its upward motion.
No, a thrown ball will never reach the same height on its way down as it did on its way up. This is due to the loss of energy from air resistance and friction with the ground. The ball will always reach a lower height on its way down due to these factors.
