Answer: yes velocity because velocity is traveling in the same direction at the same speed so yes it is traveling in a straight line
No. An object traveling at a constant velocity is not accelerating.
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Yes, the velocity is changing. Velocity is a quantity composed of the speed and the direction of motion. Constant velocity means: Constant speed, in a straight line. If the direction is changing, then the velocity is changing, even if the speed is constant.
If you accelerate, your velocity isn't constant.
Constant velocity means constant speed in a straight line.
If the velocity of the object is constant, then the net force on it is zero.(Incidentally, if the velocity of the car is constant and not zero, then it must be ona straight highway. If the highway curved and the car's velocity didn't change, thenit would run off of the road.)
It means that the velocity doesn't change over time. It's speed is always the same, and it moves in a straight line.
Imagine you are driving in your car on a straight, flat highway. Neglect curvature of the earth. You set the cruise control and stay in your lane without having to steer. Now you are traveling at a constant speed in a constant direction. This is an example of constant velocity.
If you are traveling in a constant direction with constant speed there are no changes in velocity, so you are not accelerating.
When something is traveling at a constant velocity it has no acceleration. In other words your answer is 0.
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Not necessarily. Constant velocity also means no change in direction.
Yes this is possible, when the velocity is constant. When velocity is constant there is no change in velocity, if there is no change in velocity then is no acceraltion. e.g. : a car traveling at a constant speed of 40m/s
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
It means constant speed in a straight line.
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
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?
Such an object is traveling at a constant speed in a straight line. Nothing will happen to it until the forces acting on it become unbalanced, or it runs into something.
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
Yes. An object moving in a straight line at constant speed has constant velocity.
No. The direction keeps changing. Constant velocity means constant speed in a straight line.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.
