How long does it take for a droplet of rain to reach the Earth?
It depends on the size of the raindrop and the height at which it forms. The larger the raindrop, the faster it will fall. The rain falling to earth begins in clouds as fine droplets, which begin falling very slowly and then collect to form larger drops that fall faster. During the fall, the drops will break up and reform, so the falling speed can vary from 5-20 miles per hour. Rain could take anything from a few minutes to 20+ minutes depending on drop size, height and wind.
What is the definition of launch height?
Launch height is term used in aviation as optimum height for a release of missiles or bombs.
How far up from the earth is zero gravity?
Zero gravity is not a question of height or altitude, its a question about motion. You can experience something close to zero G on a roller coaster, air plane, falling elevator and sky diving. All of these involve MOTION. Just as the space station, or space ship is falling around a planet (called orbit) it is the falling, not the distance above the planet that creates zero gravity.
A Tissue and an orange fall form the same height and land at the same time how?
The tissue and the orange experience the same gravitational force pulling them down towards the ground. This acceleration due to gravity is constant for all objects regardless of their mass, leading them to fall at the same rate and land at the same time when released from the same height.
What is the difference between tide and tidal range?
Tide refers to the rising and falling of sea levels caused by gravitational forces of the moon and sun. Tidal range, on the other hand, is the difference in height between consecutive high and low tides at a specific location.
A body falling from a height towards the earth moves with uniform?
It moves with uniform acceleration due to gravity
What is uniform for an object falling from a height and non uniform?
Ignoring air resistance, the mass, weight, color, acceleration and direction of such a body are constant, whereas its speed is not. Note: "A height" is the only place from which an object can fall.
What are the examples of freely falling bodies?
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.
How equation of motion are modified for freely falling objects?
For freely falling objects, the equation of motion is modified to account only for the effects of gravity. The equation becomes: y = 0.5gt^2, where y is the height of the object at time "t" in seconds, and "g" is the acceleration due to gravity (approximately 9.8 m/s^2). Friction and other forces are typically ignored in these scenarios.
What is the formula for calculating the velocity of an object falling freely under gravity, considering the acceleration due to gravity as 2g?
The formula for calculating the velocity of an object falling freely under gravity, considering the acceleration due to gravity as 2g, is v (2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height from which the object falls.
How do you increase the time of descent of a freely falling body?
You can increase the time of descent of a freely falling body by increasing its initial height from which it falls. This will give it more distance to cover before reaching the ground, thereby increasing the time it takes to fall. Additionally, you can increase air resistance by changing the shape or size of the falling object, which will also increase the time of descent.
What is the acceleration of a freely falling object 2 seconds after it has been released from height of M?
The acceleration of a freely falling object is approximately 9.81 m/s^2, directed downwards towards the center of the Earth. Therefore, the acceleration of the object 2 seconds after being released will still be 9.81 m/s^2, assuming no other forces are acting on it.
What is the amount of work done when a freely falling body falls through a height equal to 1 meter?
Depending on its weight: the amount of work done: A its weight: M free falling body: Vi = 0 A = F.d ( Force x Distance ) = E(initial) - E(Final) = MgH(initial) - MgH(final) H is the height A = MgH with H = 1 m ... A = Mg joules
What is the kinetic energy for freely falling body at the ground level?
The kinetic energy of a freely falling body at ground level is equal to its potential energy at the starting height, assuming no air resistance or other external forces are acting on it. The kinetic energy is given by ( KE = \frac {1}{2} m v^2 ), where (m) is the mass of the object and (v) is its velocity just before hitting the ground.
At what height is falling into water fatal?
Falling into water from a height of around 50 feet or higher can be fatal due to the impact on the body.
How is gravity different for objects that freely fall down and those thrown upwards?
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
A body falling freeling from a height towards the earth moves with uniform?
acceleration due to gravity, causing it to increase its speed at a constant rate. This acceleration is approximately 9.81 meters per second squared.
