What is the net force acting if your professor's car is traveling west with a constant velocity of 55 mi-hr west on a straight highway?

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 on
a straight highway. If the highway curved and the car's velocity didn't change, then
it would run off of the road.)

Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
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.
What is velocity if the net force is 0?
If the net force on an object is zero, then velocity of the object is constant ... it moves in a straight line at a constant speed.
What characterizes constant velocity motion on a position time graph?
A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
What is light's acceleration if its traveling at a constant speed of 300000 km s?
It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
Determine the net force on a car moving in a straight line at constant speed?
If traveling at constant speed in a constant direction then net force is zero as there is no acceleration. Acceleration would change one or the other, or both. F = ma = m (0) = 0
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
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.
If you are traveling around a curve at a constant speed of 30 km is the veiocity change?
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.
What does it mean when an object is traveling with a constant velocity?
It means that the velocity doesn't change over time. It's speed is always the same, and it moves in a straight line.
Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
What is constant velocity in terms of physics?
Constant velocity means constant speed in a straight line.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
When something is traveling at a constant velocity it has no acceleration. In other words your answer is 0.
What will happen to an object moving at constant velocity?
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.
What is the acceleration of a ball that is traveling at a constant velocity of fifty miles and has been traveling for over 2 minutes?
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
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?
A student riding her bicycle on a straight flat road covers one block every 7 seconds if each block is 100m long she is traveling at?
Constant speed and constant velocity
Can an object traveling at constant velocity have acceleration why?
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.
