## What was the conclusion of the Cavendish experiment?

The Cavendish experiment was significant not only for measuring Earth’s density (and thus its mass) but also for proving that Newton’s law of gravitation worked on scales much smaller than those of the solar system.

## What is the value of G Class 9?

G is the universal gravitational constant, G = 6.674×10-11m3kg-1s-2.

## What is the acceleration of free fall for Class 9?

Answer: When objects fall towards the Earth under the effect of gravitational force alone, then they are said to be in free fall. Acceleration of free fall is 9.8 m s−2, which is constant for all objects (irrespective of their masses).

## Why is free fall important?

Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

## Is free fall an inertial frame?

It is a well known fact that a free fall frame of reference is an inertial frame, and it is undeniable that an object in free fall is experiencing a force, therefore, it immediately does not fit with the statement of Newton’s first law, which states that in the absence of a force, an object will remain at rest or …

## How fast do you freefall?

Terminal velocity is the fastest you’ll fall during your jump; typically around 200 kph (120 mph). Your first few seconds in freefall will be a wee bit slower, so you’ll cover a little less distance at first, but then you’ll accelerate to full speed.

## Can you breathe while skydiving?

You can breathe while skydiving. In fact, we actively encourage breathing while skydiving. (Breathing regularly is super-good for you.) Even in freefall – at speeds up to 160mph – you can easily get plenty of oxygen into those airbags.

## What happens to your body if you fall from a plane?

When the plane goes into a dive, your body and the plane will eventually be falling at the same rate and it will appear that you are weightless within the plane. Your body will rise from your seat, your limbs will float, and objects around you will hover, as if you are in space.

## How dangerous is a HALO jump?

Health risks All types of parachuting techniques are dangerous, but HALO/HAHO carry special risks. At high altitudes (greater than 22,000 feet, or 6,700 m), the partial pressure of oxygen in the Earth’s atmosphere is low. Oxygen is required for human respiration and lack of pressure can lead to hypoxia.

## What is the point of HALO jumping?

So – what is a HALO jump? In short, it is a high altitude skydiving jump – and as such, it is special! This type of jump is typically used by the military to deliver people and equipment into hard-to-reach corners of a combat zone, unsuited to regular aircraft landings.
