For an automobile to travel at a constant velocity, the net force acting on the car needs to be zero. This means the forces pushing the car forward (engine power) must be balanced by the forces resisting its motion (friction, air resistance). Additionally, the car must maintain a balanced speed and direction without any external influence.
When you travel in a circle at a constant speed, your velocity (direction and speed) is constantly changing as you move along the curved path. This change in velocity indicates that there is an acceleration acting on the object, known as centripetal acceleration, which is directed towards the center of the circle. This acceleration is required to keep the object moving in a curved path at a constant speed.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
In order for an object to travel with constant velocity the sum of forces acting on it must be zero
Such an object is said to travel at a constant speed. If it doesn't change direction, it is also said to travel at constant velocity.
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?

Yes. Gamma Rays are photons (like visible light, just at another part of the electromagnetic spectrum). They travel with constant velocity at the speed of light (only in a vacuum). Although the original speed of the gamma ray varies.

Yes, all xrays travel at the speed of light.
It will fly exactly .

Assuming its engines are off, it would travel at a constant speed ONLY if there is no force of gravity that changes its velocity. In practice, there are always forces that will change its velocity, at least in the long term.

3.6 x 119 = 428.4 Therefore, the automobile will travel 428.4 kilometres.
Mass measured in kilograms and in pounds. If you travel at a constant velocity, the time that you travel and the distance that you cover.
