What causes a falling object to reach terminal velocity?
Its the air resistance that causes the free falling body to reach its terminal velocity
Is orbital velocity the velocity a rocket must reach to fly off into space?
No.Orbital Velocity is the velocity required by a body to achieve a circular orbit around its primary.Escape velocity is the minimum velocity needed to escape a gravitational field
What is the magnitude of average velocity?
Not directly. acceleration is the rate at which velocity changes, but unless near light-speed the only reason velocity would cause any difference to acceleration would be due to forces which are proportional to velocity, such as drag or friction. Near the speed of light time bends so a body would, compared to the rest of the universe, appear to decelerate so as to reach a maximum velocity of the speed of light.
What happens to a body if it travels with a speed greater than velocity of light?
It is not possible for a body to travel faster than the speed of light. It isn't simply a matter of technological insufficiency; it's a fundamental physical limit. With the expenditure of sufficient energy, it is theoritically possible to approach the speed of light, but light speed cannot be achieved by any body with mass, hence neither can it be exceeded. I'm so bored
What changes a body's velocity?
A force changes a body's velocity.
When a body has velocity no constant has acceleration or no?
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
What is the schwarzschild raduis?
The Schwarzschild radius is a concept related to black holes. Given a body it is the radius such that, if all the mass of the body were squeezed (uniformly) within that sphere, then the escape velocity at the surface of the velocity would be equal to the speed of light.
What does the term 'escape velocity' mean?
Escape velocity is what a moving body has to achieve in order not to be pulled back down to the planet. For Earth it is about 7 miles per second.
Is it possible for an electron to exceed the speed of light as it is revolving around the nucleus of an atom as well as travelling through space?
No the theory of relativity clearly states that it is impossible for any body with mass to attain light velocity m = m0/(1 - v/c)1/2 from this it is clear that if a body attains light velocity its mass will be infinity which is impossible.
When a body has constnat velocity what is the acceleration?
The acceleration is zero for a body having constant velocity.
When travelling at speed of light do you see your body while moving or does it fall behind as you are faster than the light you are seeing with your eyes?
According to our understanding of physics (which is always susceptible to modification in the light of new facts), no physical object can ever travel AT the speed of light. As physical objects are accelerated to NEARLY the speed of light, the perception of time begins to slow down, and if we ever were to reach the speed of light, time would stop completely. This "slowing of time with high velocity" is an observable fact; this DOES happen. While no humans have ever traveled at any fraction of the speed of light, scientists like Einstein and Hawking have proposed "thought experiments" in which they think through what would happen. To the observer, everything will continue to appear normal - to THEMSELVES.
Is it possible for a body to have its velocity and acceleration pointing in opposite directions?
Sure. Anything that's slowing down has velocity and acceleration in opposite directions. -- A ball tossed up in the air has upward velocity and downward acceleration. -- A car stopping for a red light has forward velocity and backward acceleration.
