On earth, a 1-kg ball in free fall has a force of roughly 9.8N acting on it. A 2-kg ball would have 19.6N.
F=m*a
F is force
m is mass
a is acceleration (on earth it's 9.8 m/s^2)
BUT air resistance is also a factor, and resistance to motion in a fluid (air in this case) depends on velocity.
The force of gravity affects the speed of a ball falling by pulling it downward, causing it to accelerate as it falls. The greater the force of gravity, the faster the ball will fall.
acceleration due to gravity acting on it, which causes it to increase in speed as it falls. The force of air resistance also acts on the ball, gradually slowing it down. Eventually, the ball reaches terminal velocity, where the force of gravity is equal to the force of air resistance and the ball falls at a constant speed.
Examples of freely falling bodies include an apple falling from a tree, a skydiver jumping out of a plane, and a rock dropped from a cliff. These objects fall under the influence of gravity with only the force of gravity acting upon them.
The force that causes the ball to fall to the ground is gravity. Gravity is a natural force that attracts objects towards each other, and in the case of the ball falling, it is being pulled towards the Earth's center by the force of gravity.
-- Recall Newton's Second Law of Motion: F = (M) x (A)-- Say it in words: "The Force on a ball is equal to the mass of the ball multiplied by its acceleration."-- Look up the acceleration of gravity. It's 9.8 meters per second2 .-- Put the mass and the acceleration into the formula :F = (1) x (9.8) = 9.8 newtons .Notice that this is also the "weight" of the ball.

When you drop a ball, the action force on the ball is the force of gravity pulling the ball towards the ground.
The force that the ground exerts on the ball to stop it instantly is equal to the change in momentum of the ball over the time it takes to stop. This force will be greater than the force of gravity acting on the ball. Additionally, the force applied by the ground will need to overcome the force of gravity and provide an equal and opposite force to cancel out the ball's downward momentum.
The idea is to calculate the downward force of gravity, and then subtract the air resistance, since it acts in the opposite way. This assumes that the ball falls directly downward.
The speed of a freely falling ball would increase by approximately 9.8 m/s every second due to gravity. This acceleration of 9.8 m/s^2 is the acceleration due to gravity on Earth.
When holding a ball, the two forces being exerted on the ball are gravity pulling the ball downward toward the Earth, and the force you apply by holding the ball to prevent it from falling.
Since gravity attracts the ball downward, and air resistance acts upwards (assuming that it falls straight down), you need to subtract the force of gravity (i.e., the weight) minus the air resistance.
Gravity is the force that gives a thrown ball its vertical movement. As the ball is thrown upwards, gravity acts on it, pulling it back down towards the ground. The vertical movement of the ball is a result of the interaction between the force of the throw and the force of gravity.
