Why does a car traveling at constant speed can accelerate while a car at constant velocity connot?
The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?
What 2 things change when an unbalanced force is applied to an object?
When the forces on an object are unbalanced the changes that could happen are the object speeds up, or slows down. And it can changes direction.
What happens to the forces of an object when it reaches a constant speed?
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
How could you describe a situation where an object velocity does not change?
if velocity is constant, that means then the net acceleration acting on the object is equal to zero
According to Aristotle an object with no forces in it will?
An object with no forces in it will eventually stop moving, according to Aristotle. Aristotle was a Greek philosopher. He was born in 384 BCE.

Can a body have a constant velocity and still be accelerating?
No. Acceleration is defined as the rate of change of velocity. If velocity is constant, then its rate of change is zero. --------------------------------------------------------------------------- Another contributor obfuscated: If we were to get really picky with our vectors we could say that an object could have constant velocity in the x-y plane and still accelerate in the z-axis. Also a system of objects could have a net-velocity in 3-D space and still have a radial acceleration. A solar system traveling through space at constant velocity will have a radial acceleration, for each component part of the system, around the gravitational center of mass of the system.
If the net force on an object is zero then the object is?
Not accelerating. It could be stationary or moving at a constant speed.
What is single number without a variable?
Constant, perhaps scalar constant. Since you could have a constant vector or other object, as well.
Why must a force be exerted in an object ti change its velocity?
We know that that is the way our Universe works; WHY the Universe was designed that way, or why it happens to be that way, is normally not known.In this case, with a different law for velocity, lots of the physics we know would be drastically different - for example, conservation of energy, conservation of momentum, and conservation of angular momentum could all be violated.

When the forces on an object are unbalanced the changes that could happen are the object speeds up, or slows down. And it can changes direction.
How would you find the mass of an object if there were no gravitational force?
Mass is defined as resistance to acceleration, so one could measure how much force is needed to accelerate the object.
The net force of an object is zero can you conclude that the object is at rest?
You can't. The net force simply means that the acceleration is zero. It could be at rest, or the object could be moving at a constant velocity.

An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.

If a car drove a around in a circle would that be constant velocity?
No. Velocity is a 'vector', which means it's a measurement that has both magnitude and direction. The magnitude is what we usually call the 'speed'. For an object moving in a circle, it could have constant speed ... the velocity could have constant magnitude ... but there's no way the whole velocity vector could be constant, because the direction is always changing. Constant velocity is very easy to recognize ... the object is moving at a steady speed, in a straight line.
