Does acceleration due to gravity depend on mass?
The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does.
Why does mass resist acceleration?
The more mass an object has the more weight it will have. Weight is caused by the force of gravity acting on the mass of an object. Because the mass increases the object’s inertia, more force is needed to move the object, and therefore mass is a resistance to acceleration.
What would happen if we didn’t have Newton’s third law?
Without the third laws existence you could not walk. For every action there is an equal and opposite reaction. Suppose the action is that you push on the ground with your foot, there would be no reaction to push you forward.
How do you calculate the force of gravity in Newtons?
We can do this quite simply by using Newton’s equation: forcegravity = G × M × mseparation2 . Suppose: your mass, m, is 60 kilogram; the mass of your colleague, M, is 70 kg; your centre-to-centre separation, r, is 1 m; and G is 6.67 × 10 -11 newton square metre kilogram-2.
How fast is a supernova shockwave?
approximately 30,000 km/s
What would happen if you stood on a neutron star?
Which means that any object caught in a neutron star’s gravity would be accelerated to a tremendous speed. If you are not ripped apart during your descent (you would be), all of your atoms would most likely be destroyed upon impact. Essentially, you would be turned into a pile of neutrons.
What would happen if a black hole hit a neutron star?
One unusual discovery was that, in dense clusters, a black hole and a neutron star could merge without generating any detectable light, although the merger would still generate an extraordinary number of gravitational waves.
Could you survive live on a neutron star?
No. A neutron star has such an intense gravitational field and high temperature that you could not survive a close encounter of any kind. You would become a puff of gamma rays and X-rays, as your light elements were transformed into a cloud of heavy elements, neutrons and ultra-relativistic electrons.
Do neutron stars spin?
Neutron stars form when a massive star explodes at the end of its life and leaves behind a super-dense, spinning ball of neutrons. Most pulsars rotate just a few times per second, but some spin hundreds of times faster.
