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
If a body falls freely from infinity then it will be striking the earth with what velocity?
The body will be striking the Earth with a velocity equal to its escape velocity, which is around 11.2 km/s. At this velocity, the body will have enough kinetic energy to overcome the gravitational pull of the Earth and reach the surface.
If a body starts from rest what can be said about the acceleration of body?
If a body starts from rest, it means its initial velocity is zero. In this case, if the body is in motion, it has undergone acceleration to reach that velocity. Therefore, the acceleration of the body must be non-zero, indicating a change in velocity over time.
The velocity a rocket must reach to establish an orbit in space is?
The velocity a rocket must reach to establish an orbit in space is called orbital velocity. It depends on the altitude of the desired orbit and the mass of the body being orbited. In general, orbital velocity is around 28,000 km/h for low Earth orbit.
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.

What is escape volocity?
Escape velocity is the minimum speed that an object must reach to break free from the gravitational pull of a celestial body. This velocity allows the object to overcome the body's gravitational force and enter into space. The specific value of escape velocity depends on the mass and radius of the celestial body.
What is the magnitude of average velocity?
The magnitude of average velocity is the total distance traveled divided by the total time taken, regardless of the direction. It gives the overall speed at which an object has moved over a certain period.
What changes a body's velocity?
A force changes a body's velocity.
Can a free falling body reach the speed of sound according to newton?
According to Newton's laws of motion, a free-falling body accelerates due to gravity, increasing its velocity as it falls. However, it can reach terminal velocity, which is the maximum speed it achieves when the force of air resistance equals the force of gravity. This terminal velocity is typically much lower than the speed of sound, especially for objects with a large surface area relative to their mass. Therefore, a free-falling body cannot reach the speed of sound in a normal atmospheric condition.
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.
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.
How high do you have to be to reach terminal velocity?
Terminal velocity is the maximum speed an object reaches when falling through a fluid (such as air) due to balance between gravity and air resistance. The exact height you need to reach to achieve terminal velocity varies depending on factors like your weight, body position, and the specific characteristics of the air around you. In a general sense, skydivers typically reach terminal velocity within about 10-12 seconds of freefall from an altitude of around 12,000 feet.
