What is the force on a 1-kg ball that is falling freely due to the pull of gravity?

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 net force is the weight of the object (with no air resistance):
W = mg = (1kg) x (10N/kg) = 10N
When the air resistance balances out with the weight of the object, the ball will stop accelerating because the ball has already reached terminal velocity. In this case, the resultant force is 0.

∙ 13y agogravity, which has an acceleration rate of -9.81 m/s^2 (meters per second squared) at sea-level on earth. This is assuming air resistance is negligible, thus having no net force, especially compared to the significance of gravity. In a vaccuum, a Bowling ball and a feather fall at the same rate because air resistance isn't present

Find the net force by vector addition of the weight of the ball and air resistance.
Forcenet = -9.8N + 2N = -7.8N = -8N rounded to one significant figure.

∙ 12y agoAlthough it's not stated in the question, we'll assume that this whole drama is
playing out near the Earth, where the acceleration of gravity is 9.8 meters/sec2.
The downward force on the ball, due to gravity, is (mass x gravity) = 9.8 newtons.
If the upward force due to air resistance is 2 newtons, then the net force on the ball is
(9.8 down) + (2 up) = 7.8 newtons downward.

(That's called the "weight" of the ball.)

A ball falling through the air has?
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.
What force causes the ball to fall to the ground?
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.
What is the net force acting on a freely falling 1-kg ball if it encounters 2 N of air resistance?
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.
What are the steps to solving what is the force on a 1-kg ball that is falling freely due to the pull 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.

What force act on the ball when it is in the air?
The force that acts on a ball when in the air is gravity.
What is the meaning of free falling and how is it related to force?
Free falling isn't actually related to force, when you free fall you are falling because of gravity, gravity is one of the four known forces, but gravity is simply the warping of the fabric of space and time, you fall because the earth streches that fabric, and you fall or sink into it, like a bowling ball on a trampoline. There are no forces acting on you, rather you are simply moving with the fabric which you exist in, which has been warped by the force of gravity. Free Fall is where an object whose motion is due to gravity ALONE.
When a ball is in the air is work being done?
If the ball is falling, then work is being done.Work is the product of (force) times (distance). The ball in the air has force acting on it, created by gravity, and known as the "weight" of the ball. If the ball is falling, then the work done on it by gravity is (its weight) multiplied by (the distance it falls).If the ball is accelerating up, then something has to be providing force greater than its weight, in order to lift it against the force of gravity. It may be a muscle, a motor, an elevator, or some kind of air-foil taking energy out of wind. The work done on the ball is (the upward force on it) multiplied by (the distance it's lifted).If the ball is moving only horizontally, and not the slightest bit up or down, then almost no work is being done, since there's no significant horizontal force acting on it. The ball does a small amount of work to move air as it moves through the atmosphere.
What force pulls a ball down?
Gravity.
What force is acting on a ball when it is not moving?
Gravity
What force acts on the bowling ball?
Gravity and normal force (floor pushing on the ball) if its already rolling. If it's being thrown, then gravity, normal force, and the hand throwing it.
What moves faster a ball thrown down or a ball falling down?
A ball thrown down. The thrown ball will have a greater initial velocity and since they experience the same force of gravity, it will always be faster (until they both reach terminal velocity).
