If a car is traveling on the highway at a constant velocity the force that pushes the car forward must be?

1. force that moves a car forward is the friction force between the tires and the road (ignoring what is going on mechanically in the car)
2. if the car is travelling at constant velocity, net force is zero - forces pushing car forward are equal to forces pushing car back

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 ona straight highway. If the highway curved and the car's velocity didn't change, thenit would run off of the road.)
What is an example where speed becomes constant but velocity changes?
Taking a turn on the highway.
What is an example of something at constant speed but not constant velocity?
You are driving your car with cruise control but you steer around a bend in the highway. The cruise control keeps your speed constant, but by steering you change your direction and thus your velocity is not constant.
Traveling down a highway a car changed velocity while its speed remained constant.what would have caused this to happen?
This may have been the result of steering the car around a curve in the road while maintaining constant speed.
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
If A car travels down the highway at 55 mph its speed is what and its acceleration is what?
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
What are some examples when speed remains constant but the velocity changes?
Velocity is a vector; velocity tells you how fast something is traveling (speed),and its direction. A change in velocity could indicate a change in direction orspeed, or both.
If an object traveling in one direction has a positive velocity what kind of velocity would the same object traveling in the opposite direction have?
Regardless of the direction being travelled, any object on the move has a positive velocity, even if it is moving backwards, because velocity is the measure of the rate of movement in a given direction. Compare: A car is traveling forwards on a highway at 100 km/h. How fast is it travelling? If it turns round (or even it doesn't turn round, but just reverses) and travels at 100 km/h, how fast is it travelling? The answer is 100 km/h in both cases. (But reversing on a highway and travelling at 100 km/h is not recommended!)
A truck is traveling east on a highway at 80 km h What is velocity?
Velocity is speed and direction. Truck speed is 80 km/hr. Truck velocity is 80 km/hr going east. Its velocity is also -80 km/h going west, and 0 km/h going north or south.
Diffrence between velocity and acceleration?
Velocity is the constant distance that is traveled by a body per unit of time. Acceleration is the rate at which the velocity can change. On a straight highway, you put your car under cruise at 65mph. The car travels (except for the imperfections on the road) at this constant speed. The speedometer stays almost at 65. That is as close an example I can give you for velocity. On the other hand you enter a highway from a ramp, you usually press on the accelerator hard to gain speed to merge into fast moving traffic. The speedometer rapidly changes from say 10mph to 20mph to 23 mph.... and so on and this is acceleration.
What highway to use traveling San Francisco to carmel?
Highway 1
How velocity use in a sentence?
Velocity basically just means speed. We drove at a high velocity down the highway.
