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.

What is the acceleration that occurs when an object moves at a constant speed in circular motion called?
It's called 'centripetal acceleration', whether or not the speed is constant or the path circular.
Formula for distance traveled?
There is not enough information to answer the question. The answer depends onis the object travelling at constant velocity?is the acceleration constant?If it is an object travelling with constant acceleration, which three of the following four variables are knows: initaial velocity, final velocity, acceleration and time.
How are constant speed and constant acceleration different?
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
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.
Examples of constant speed but changing acceleration?
A body moving with constant speed in a circular path has acceleration changing at every point.
What is the acceleration that occurs when an object moves at a constant speed in circular motion?
It's called 'centripetal acceleration', whether or not the speed is constant or the path circular.

Is acceleration uniform in uniformly circular motion?
No, acceleration is not uniform in uniformly circular motion. In uniformly circular motion, the direction of the velocity vector is constantly changing, which means there is always a centripetal acceleration acting towards the center of the circle. This centripetal acceleration is not constant in magnitude, making the overall acceleration not uniform.
Is it possible to experience centripetal acceleration but not tangential acceleration?
Yes, it is possible to experience centripetal acceleration without tangential acceleration. Centripetal acceleration is the acceleration directed towards the center of a circular path, while tangential acceleration is the acceleration along the direction of motion. In cases where an object is moving in a circular path at a constant speed, there is centripetal acceleration but no tangential acceleration.
What is an example of Circular acceleration?
a satellite in orbit; it is moving at constant speed but is accelerating outward in circular acceleration, balanced by gravity acceleration (centripetal force).
What is constant acceleration due to only a change in direction?
Constant acceleration due to only a change in direction is known as centripetal acceleration. This acceleration always acts towards the center of the circular path and is responsible for keeping an object moving in a circular motion. It does not change the speed of the object, but only the direction of its velocity.
Is uniform circular motion accelerated?
Yes, uniform circular motion involves constant speed but changing direction, which means there is acceleration present in the form of centripetal acceleration directed towards the center of the circular path.
Why does acceleration occur with centripetal motion?
Acceleration occurs with centripetal motion because the direction of motion is constantly changing, even if the speed remains constant. This change in direction results in an acceleration towards the center of the circular path, known as centripetal acceleration. This acceleration is necessary to keep an object moving in a circular path and prevent it from moving in a straight line.
In uniform circular motion quantities are constant?
In uniform circular motion, the speed of the object remains constant, but the velocity changes direction continuously. The acceleration is directed towards the center of the circle (centripetal acceleration) and its magnitude remains constant. The object moves in a circular path at a constant speed.
Can a car move around a circular racetrack so that the car has a tangential acceleration but no centripetal acceleration?
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
How to find maximum centripetal acceleration?
The maximum centripetal acceleration is found by equating it to the centripetal acceleration formula: ac = v^2/r, where v is the velocity of the object and r is the radius of the circular path. The maximum centripetal acceleration occurs when the object is moving with the highest velocity and has the smallest radius of curvature in its path.
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.
