For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
When you run around a track at 5 km and h your velocity is constant?
sure.
A race car is travelling at constant speed around a circular track What happens to the centripetal acceleration of the car if the speed is doubled?
It increases by a factor of 4, because Fc = (mv2)/r. Fc = ma. so we conclude that the relationship between a and v is a squared relationship.
If a car travels at a constant speed is it accelerating?
No. Acceleration is the change in velocity(speed) over a period time.=====================================Another contributor bristled:Sorry. Velocity and speed are not two different words for the same thing.Velocity means speed and direction, and acceleration means any change in velocity.If the speed is constant but the direction is changing ... like turning a corner or drivingon a circular track ... then velocity is changing, and there is acceleration.
If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes What was the jogger's average speed in meters per second?
If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes his average speed (pace) is 1.0285 meters per second.
When you run around a track at 5 km h your velocity is constant?
No. Your speed is constant but your velocity is not. Velocity is a vector and as you run around a track, the direction of your motion changes and so the velocity changes - not in magnitude but in direction.
For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Is a Nascar race driver able to drive his race car around the circular track with a constant speed?
no
Which describe acceleration involving only a change in directions?
This type of acceleration occurs when an object is moving around a circle at a constant speed. As the object moves around the circle, the direction of its velocity is constantly changing. This type of acceleration is called centripetal acceleration. The direction of the acceleration is toward the center of the circle. I hope this answers your question. A car traveling 25 MPH turns 30-degrees to the left without losing speed -- it has accelerated.
A race car is traveling at constant speed around a circular track what has to happen to the static friction in order to stay on the track when the speed is doubled?
In that case, the centripetal acceleration - and therefore also the static friction - will increase by a factor of 4.
Explain why velocity changes while driving around a circular track even if the speed is constant?
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
A cyclist goes around a level circular track at constant speed. Is the cyclist's acceleration zero because her speed is constant?
No. The cyclist is moving at a constant speed, but her velocity is changing. Remember that velocity is speed with a direction vector associated with it. As speed is constant, only direction is changing. But a change in direction is a change in velocity (even if speed is constant), and this requires acceleration in that direction to accomplish the change in direction. You're on the right track, but just recall that acceleration is tied to velocity and not just speed. And note that velocity can change all the time without speed changing. Acceleration must cause the change in velocity. Consider that objects in orbit around the earth move at a pretty constant speed, but accelerate toward the earth all the time. Their speed coupled with their acceleration toward earth cause them to move in an arc - which is their orbital path.
Is a car on a circular track has also constant velocity?
Yes, IF it maintains constant speed on the track. The academic definition of velocity is speed and the associated direction, a vector. A car traveling in a circle is constantly changing direction. However, most people, including physicists when they are not writing textbooks, treat velocity and speed as interchangable such that a car going a constant speed on a circular track would be considered to have a constant velocity even though the direction in which it is traveling is constantly changing.
Can an object be accelerated if it is moving with constant speed?
Yes. The simplest such case is when the object is moving along a circle.
Is constant speed current velocity?
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
What identifies a change in motion that produces acceleration?
A ball moving at a constant speed around a circular track.
What process is primarily responsible for the increase of speed and sound on a rail road track?
The speed of sound depends on the medium. There is no particular process that will simply increase the speed of sound.
