The speed of light is, theoretically, the maximum speed achievable by any particle or the maximum speed which information may be transfered. There are things that we know of that travel faster but are incapable of carrying information. An example is wave guides. There is a book the title of which is "Things that Travel Faster than Light" which explains this more fully However, since light travels at different speeds in different media, it is possible for something to travel faster than the speed of light in, say, water. This produces Cherenkov radiation ... the blue glow you may have seen in pictures of nuclear reactor cores.

∙ 9y agoNothing. Nothing can travel faster than light.
=========================================
Any distance longer than 299,792,458 meters, covered in less than 1 second by your clock,
is more than light speed.
As noted in the first answer, above, nothing can travel at such a speed.

∙ 11y agoNo, that isn't possible. As objects accelerate toward the speed of light, there are what are known as relativistic effects. Objects get heavier, time slows down, and you can never get to the speed of light, although you can get arbitrarily close to that speed if you have enough energy for propulsion.
Somewhat paradoxically if two objects were to approach each other at 3/4 the speed of light relative to some other fixed third object, they would NOT close the distance between them faster than the speed of light.
The special relativistic formula for adding velocities to determine a relative velocity between approaching or receding bodies is:
V = (v1 + v2)/ [1 + (v1 x v2)/c2]
so that if
v1 = 0.75c and v2 = 0.75c then
V = (0.75c +0.75c)/[1+(0.75c x 0.75c)/c2] = 0.96c (approximately).
Neither could they move apart faster than the speed of light even if they were going 3/4 the speed of light relative to an object half-way between them. The rule of not exceeding the speed of light still applies to the velocity of one object relative to another.

Does a heavier object always have more inertia than a lighter object?
Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.So assuming they are turning at the same angular velocity, the heavier one has a larger inertia. Otherwise, remember that inertia is also proportional to angular velocity.
The more mass an object has the harder it is to change its what?
Its velocity.Its velocity.Its velocity.Its velocity.
What defines a point at which an object will not accelerate any more?
Terminal velocity defines the point at which an object will no longer accelerate. When a falling object reaches terminal velocity, it will continue to fall at a constant speed.
Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
What is the definition of vertical velocity?
Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity.
Can an object have velocity more than light?
no

When an object is accelerating if its?
An object accelerates if its velocity changes. More precisely, "acceleration" is the rate of change of velocity (how quickly velocity changes), or in symbols, dv/dt.

Its velocity.Its velocity.Its velocity.Its velocity.
What defines a point at which an object will not accelerate any more?
Terminal velocity defines the point at which an object will no longer accelerate. When a falling object reaches terminal velocity, it will continue to fall at a constant speed.
What do you have to change for an object to have more kinetic energy?
Increase its velocity
What is the relationship between momentum and mass?
The more the mass, the more momentum you will need for an object to speed up more, or accelerate.
Why do you need to calculate velocity instead of speed?

How does air resistance affect the velocity of an object?
Acceleration is a change in velocity. More precisely, to get acceleration, you divide the change in velocity, by the time that passed.Acceleration is a change in velocity.

When equals the foce of gravity on a falling object the object reaches terminal velocity?
Yes any other force such as viscous dragging force becomes equal to the weight of the falling object then the body would be moving with uniform velocity. Hence no more increase in the velocity as there is no net acceleration. And so the velocity is said to be terminal (recall terminus) velocity.
What is the greatest velocity a fallen object reaches?
If air resistance is significant, after falling for a while the air resistance will be as strong as the force of gravity; the two forces will be in equilibrium, and the object won't accelerate any more. This velocity is called "terminal velocity". The amount of this terminal velocity, and the time it takes to approach the terminal velocity, depends on the specific object that is falling.
What is the definition of vertical velocity?
Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity.
