Can moving objects be a reference point?
No because enable to see if the object is moving it needs a reference point other than itself.
When you drive down the highway you are moving through space what else are you moving through?
Through the air, which offers resistance proportional to the speed squared.
If you increase the force on an object what else do you probably also increase?
A very simple answer for an unspecific question: Force = Mass x Acceleration If you increase the force acting on an object you will also increase that objects acceleration (If the force on a stationary object is enough to overcome friction or if the force is in the same direction that an object is already moving, etc.).
What are the forces acting on an object without acceleration?
The net force that is acting on an object that is not changing speed is centripetal force that is pulling the object into a circular path. However, just to be clear on this point, while the object's "speed" is not changing, it's "velocity" certainly is, because velocity, unlike speed, has a directional component to it.
What is a measurement scale that has no meaningful absolute zero point?
Speed. Speed is always considered in relation to something else -- if you are moving at 50mph, and something passes you at 70mph, it is going 20mph relative to you. But even saying 50mph or whatever is relative to the Earth only -- the Earth is moving around the sun, the sun is moving through the galaxy, the galaxy is moving in relation to other galaxies, etc. Modern physics tells us that there is no "motionless" point from which you can measure everything else, therefore it doesn't really make sense to think of there being an 'absolute zero' when it comes to speed. Also, a scale such as IQ, which defines one's performance in relation to how others perform, would not have a meaningful 'absolute zero'.
If the speed of a moving object triples then what else increasses by a factor of three or more?
velocity by 3xmomentum by 3xenergy by 9x
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.
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.

Which forces are unbalanced?
coz if they werent, whatever they were acting on, would either stay sill, or move at a constant speed
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.
Can moving objects be a reference point?
No because enable to see if the object is moving it needs a reference point other than itself.
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.
When you drive down the highway you are moving through space what else are you moving through?
Through the air, which offers resistance proportional to the speed squared.
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)
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.
