What does speed is relative mean?

It means there's no answer to the question "How fast is it really moving ?", because there'sno such thing as "real" motion. Motion always means "compared to" something else.Did you ever read a book while you were sitting in an airliner that was flying past the groundat 400 miles an hour ?"Relative to" the ground, the airplane was going 400 miles an hour. And so was the book.But relative to you, the book wasn't moving at all; its speed was zero.Which speed was real, 400 mph or zero ? They were bothreal, and neither one was more realthan the other one.Motion, speed, distance, and place, are always "compared to" something else.


What is velocit?

Subconsciously driving over the speed limit after leaving an expressway


Can moving objects be a reference point?

No, moving objects cannot be a reference point because a reference point is typically a fixed point used to determine the position or motion of other objects. Using a moving object as a reference point would make it difficult to accurately measure or describe the position or motion of other objects relative to it.


When you drive down the highway you are moving through space what else are you moving through?

When driving down the highway, you are moving through time, as time is continually passing regardless of your speed. Additionally, you are also moving through an ever-changing environment, encountering different landscapes, weather conditions, and other vehicles along the way.


Do we mean by displaces?

Displacement generally refers to the act of moving something from its original position or replacing it with something else. In physics, it specifically refers to the change in position of an object.

Is power of the object moving with constant force and velocity can be meaured?

Please slow down. A few points need to be clarified here: -- There's no such thing as "moving with constant force". -- If the object exerts a force on something else, or a constant force acts on the object, then the object can't move with constant velocity. It must accelerate. -- A moving object has energy, but it doesn't have 'power'. Power is the rate at which energy is moving, or changing, or being used. If the object is moving with constant velocity, then its energy is not changing. -- If its energy is changing, then its velocity, or position, or temperature is changing. Either the object is transferring energy to something else (like brakes), or something else is transferring energy to the object (like an engine). Either way, the rate at which power is exchanging between the object and something else is the power. But there's no such thing as "power of the object". Now, what was it you were saying ? The energy of the object can be calculated, if we either know or measure its mass, electric charge, altitude, speed, temperature, etc.


What does an upward sloping diagonal line mean in position vs time graph?

It means that either the distance is measured from the starting-line and the object is moving forward, or else the distance is measured from the finish-line and the object is moving backwards, because the distance is growing as time goes on. If the upward sloping diagonal line is straight, it means the speed is constant. (not velocity)


Why doesn't a moving object last forever?

A moving object stops moving due to friction. Friction may come from the surface on which it is rolling, the air through which it is moving, etc. Objects in a vacuum theoretically, will not stop moving until they run into something else.

What are the conditions for an object to stay at restto keep moving at constant velocity?

"Constant velocity" means neither the speed nor the direction of the object's motion is changing. "Rest" is just one kind of constant velocity ... the kind with zero speed. The condition for an object's velocity to remain constant is: Either there are no forces acting on the object, or else all of the forces acting on it add up to zero. If there is any NET force acting on the object, then its velocity will change ... it will either speed up, slow down, or curve in a new direction.

How fast do back holes move?

Everything is moving away from everything else at the same speed, so black holes moving is relative to where you are.

How do scientists determine if an object is moving?

Doppler Shift......The wavelength of light emitted by a moving object is shifted. This effect is called the Doppler shift. The question also reveals a poor understanding of 'moving'. Each object is it's own 'rest frame', and can only be moving with respect to something else specified, representing another rest frame. For the purposes of real motion (and maximum speed c, including for the propagation of em waves) the reference is always the local background (frame). (If you are timing a car go past at max speed v, then you accelerate to v', it does not mean the car can suddenly do v+v'!, so the speed is not with respect to anything except it's local background.) The Special Theory of Relativity was valid for space that was empty (a perfect vacuum) and bodies that were perfectly rigid. We know know space is not empty and bodies are not rigid, but no other more valid or consistent theory has yet been adopted.


What is newtons first called?

Newton's First Law is called his First Law of Motion. It states that an object in motion tends to stay in motion unless influenced by something else that slows or stops its motion. Likewise, an object at rest - not moving - tends to stay at rest unless influenced by something else that starts it moving.


If you are in a moving car and if you throw a ball vertically up why does the ball fall in your hand?

Because both You and the ball (and everything else in the cabin for that sake) are moving with the same speed as the car :)
