Look up newtons 3 laws.
Forces help speed up a ball by providing it with acceleration, which is the rate of change of velocity. When a force is applied to a ball, it overcomes any resistance, such as friction, allowing the ball to move faster. The force increases the ball's momentum, resulting in an increase in speed.
When you throw a ball, it accelerates from your hand and moves through the air in a parabolic trajectory. The two main forces acting on the ball are gravity, which pulls it downward, and air resistance, which opposes its motion through the air. Gravity causes the ball to eventually fall back to the ground, while air resistance slows it down as it travels. Together, these forces influence the ball's flight path and speed.
The ball comes to a stop due to the forces of friction and air resistance acting on it. As the ball rolls along the ground, these forces exert a slowing effect on its motion, eventually bringing it to a stop.
When catching a ball, two forces are at play: a force of gravity pulling the ball downward and a force exerted by the hand or glove pushing the ball upward to stop its motion. The interaction between these two forces determines the speed and direction at which the ball is caught.
The forces on a kicked soccer ball are unbalanced because the force of the kick is greater than the force of air resistance initially. This causes the ball to accelerate and move in the direction of the kick. Once the ball reaches a constant speed, the forces become balanced.
When Jackson throws a baseball in a straight path, two primary forces cause the ball to stop: air resistance (drag) and gravity. Air resistance acts against the ball's motion, slowing it down as it travels through the air, while gravity pulls the ball downward, eventually bringing it to the ground. Together, these forces work to reduce the ball's speed and alter its trajectory until it comes to a complete stop.
When you throw a ball with a spin (screwball), the airflow on the ball creates a pressure difference between the two sides, causing it to curve. The rotation of the ball affects its trajectory by creating lift, stability, and drag forces. The speed of the throw will also affect the overall flight path of the ball.
The speed of the ball at the midpoint of its descent would be the same as the speed at the start of its descent if there is no air resistance or other forces affecting its motion. This assumes the ball was dropped from rest and gravity is the only force acting on it.
The speed of the ball will increase at the bottom of the slope due to the conversion of potential energy into kinetic energy as it rolls downhill. Assuming no external forces are acting on the ball, it will be traveling at its maximum speed at the bottom of the slope.
In the free fall of a cotton ball, air resistance acts in the opposite direction of the ball's motion. As the cotton ball falls, it displaces air molecules which create a force that opposes its movement, slowing it down. This resistance increases as the velocity of the cotton ball increases, eventually reaching a point where the forces balance out and the ball falls at a constant speed.
Friction between the carpet and the ball gradually slows down the ball's motion by converting its kinetic energy into heat. As the ball loses momentum, its speed decreases until it eventually stops moving.
The speed of the ball decreases as it moves against gravity and eventually reaches 0 at its highest point before falling back down.
