Why you cannot accelerate electrons greater than the velocity of light in free space?

Nothing can be made to move faster than the speed of light in a vacuum; for objects that move slower than light, even reaching the speed of light would require an infinite energy.

Do beta particles have low velocity?
NO about 0.99 the speed of light howeaver they are electrons ( or positrons ) so exibit wave properties so there velocity cannot be mesured due to uncirtanty
Balanced forces cannot accelerate an object.?
true
How did man fall faster than maximum velocity?
You cannot fall faster than maximum velocity. However, maximum velocity is reached when drag force has increased to the point that gravity can no longer accelerate the body. If drag can be reduced, maximum velocity is increased. If the body is falling where there is very little drag, such as very high above Earth, the body will continue to accelerate until the atmosphere that has been reached is more dense and the drag has increased, thereby reducing maximum velocity. This was demonstrated by Felix Baumgartner in the free fall 24 miles above Earths surface, when he reached a speed of 833 miles per hour prior to entering the dense atmosphere.
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?
Where on earth can a hammer and feather drop at the same speed?
Inside a safe dropped from a plane.If there were a very good vacuum to drop them in, it would be close. The air resistance of a feather limits its falling velocity more than the resistance on the hammer. When the drag caused by friction equals the weight of the object, it cannot continue to accelerate and falls at a speed called its terminal velocity.
What principle states that The location and velocity of electrons cannot be known at the same time?
Uncertainty
Can an items velocity ever be greater than it's speed?
The velocity of an object cannot ever be greater than its speed as the two are directly linked. Velocity is very similar to speed except that it also takes direction into consideration.
What principle says that the location and velocity of electrons cannot be known at the same time?
This is the Heisenberg uncertainty principle

What is the relation between lift force and mach number in supersonic speed?
The only relationship is that the greater the velocity of Air over a Lifting Body (Wing in general), the greater the LIFT. HOWEVER, you cannot say that the reverse is true...that is, the greater the LIFT the higher the Velocity. You can change Lift by changing the Wing DESIGN. When Landing an Airliner deploys its WING FLAPS to create greater Lift at lower velocities.
An electric or megnetic field cannot accelerate?
neutrons
Balanced forces cannot accelerate an object.?
true
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape

Are black holes pretty?
NO, to see something you have to be able to intercept light reflected from that thing's surface. Black holes have an escape velocity greater than the sped of light so there is no reflected light and they cannot be seen. If they cannot be seen they cannot be pretty ... or ugly.
How can we use integers to represent the velocity of a number?
You cannot because a number has no velocity.
