The Science of the Formation of Black Hole in Outer Space
Words • 707
Pages • 3
Stars are affected by two main forces: Nuclear fusion, and graVItation Black Holes are the result of an Imbalance of these two forces, Nuclear fusion- the outward force from the star‘s centre and gravitation- the force pulling inwards. These two processes balance one another until all the star‘s hydrogen is exhausted, allowing gravitation to take over. Once gravitation dominates. the star becomes unstable and starts to collapse, As the core compresses, it heats up and results in a supernova explosion…...

Black Hole a Region of Space Time
Words • 494
Pages • 2
A black hole is a region of space time with such a strong force of gravity, everything, including light, can be pulled into the black hole. Objects are pulled in once they have gone beyond the event horizon, which marks the point of no return. They are called “black" because of the fact that all the light is pulled in, so it reflects no light. Black holes are formed when massive stars reach the end of their life cycle and…...

What Is A Paper Helicopter
Words • 720
Pages • 3
If the mass of the paper helicopter increases, then the drop time of the paper helicopter will decrease because the paper helicopter with the greater mass will take a longer time to reach terminal velocity ( when there is a balance of forces and thus zero acceleration) which results in a shorter drop time because the object is still accelerating. The mass of the paper helicopter will be measured by using 5 paperclips of each . 7g and the same…...

Galileo in his rolling ball experiment investigated the acceleration of a ball rolling down an inclined plane, using a similar setup I will investigate how the time taken to roll down the inclined plane varies with the vertical height change. Theory: When two similar objects are thrown vertically downwards, they are in a state of free-fall. Both objects will hit the ground simultaneously; the force which causes these objects to fall down is the pull of gravity which is also…...
