The falling of a parachutist without his parachute deployed will be quite fast. We can slow his decsent by putting a drag on the free fall with a parachute. The fall is no longer free of drag (friction).
If an object reflects all the light falling upon it, it would appear white to our eyes. This is because white is a combination of all colors in the visible light spectrum.
As a falling object descends, its potential energy (due to its position above the ground) is converted into kinetic energy (energy of motion). This kinetic energy increases as the object accelerates towards the ground. When the object reaches the ground, all of its potential energy is converted into kinetic energy.
If you were taking distance measurements of a free falling object at one-second intervals, you would observe the object accelerating downward. Each measurement interval would show the object covering a greater distance than the previous interval due to the acceleration from gravity acting on the object.
The object's speed after falling for 2 seconds can be calculated using the formula: speed = acceleration due to gravity (9.81 m/s^2) x time (2 s). Therefore, the speed of the object after falling for 2 seconds would be 19.62 m/s.
Air resistance, also known as drag, affects the way a parachutist falls by slowing down their descent. As the parachutist falls, the force of air resistance increases with speed, eventually reaching a point where it equals the force of gravity pulling the parachutist down. This creates a situation known as terminal velocity, where the parachutist falls at a constant speed without accelerating further.
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.

A falling object would have less drag than in a classroom in a low pressure environment (higher up) or in a space or a vacuum, but then it's not really falling. Hope this clarifies.
If an object reflects all the light falling upon it, it would appear white to our eyes. This is because white is a combination of all colors in the visible light spectrum.
Let's imagine there is no air resistance and that gravity is the only thing affecting a falling object. Such an object would then be in free fall. Freely falling objects are affected only by gravity
If the Object is falling at a constant velocity the shape of the graph would be linear. If the object is falling at a changing velocity (Accelerating) the shape of the graph would be exponential- "J' Shape.
As a falling object descends, its potential energy (due to its position above the ground) is converted into kinetic energy (energy of motion). This kinetic energy increases as the object accelerates towards the ground. When the object reaches the ground, all of its potential energy is converted into kinetic energy.
A SCALE LIKE YOU WOULD WHIGH YOURSEVE ON
The parachutist will go down, of course. If gravity is greater than air resistance, then the parachutist would accelerate (his speed would increase). This would increase air resistance, up to the point where gravity and air resistance are in balance.
If you were taking distance measurements of a free falling object at one-second intervals, you would observe the object accelerating downward. Each measurement interval would show the object covering a greater distance than the previous interval due to the acceleration from gravity acting on the object.
The object's speed after falling for 2 seconds can be calculated using the formula: speed = acceleration due to gravity (9.81 m/s^2) x time (2 s). Therefore, the speed of the object after falling for 2 seconds would be 19.62 m/s.
At the end of 3 seconds, a falling object is falling at 65.8 mph faster than when it was released, ignoring air resistance.
