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 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).
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?
That depends on the situation, on the problem you are trying to solve. If speed is constant, maximal centripetal acceleration occurs where the radius of curvature is smallest - for example, in the case of a parabola, at its vertex. If the radius of curvature is constant, maximum centripetal acceleration occurs when the speed is greatest (for an object reacting to gravity, that might be at the bottom of a circular path). In other cases, you have to get a general expression for the centripetal acceleration, and maximize it (using methods of calculus).
He constant acceleration of an object moving in a circle is called?
centripetal acceleration
What is constant acceleration due to only a change in direction?
Centripetal acceleration
What is uniform circular motion?
Uniform circular motion describes motion in which an object moves with constant speed along a circular path.In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.
Is the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?
This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
Can the direction of he velovity of a body be change when its acceleration is constant?
That is what happening in case of a body moving uniformly around a circular path. Its speed ie the magnitude of velocity remains the same but every moment its direction is changed due to the constant acceleration known to be centripetal acceleration.
Why does centripetal acceleration occur?
Centripetal means towards the center. Any object moving around in a circle is accelerating towards the center. Remember that acceleration involves a change in velocity, and a specification of "velocity" includes the direction; therefore, since the direction of the movement changes continuously, the object is "accelerating", according to the definition of acceleration.
What two quantities is necessary for uniform circular motion?
The only thing required for an object to show uniform circular motion is a constant centripetal force. The object will have constant speed and kinetic energy, but its velocity, acceleration, momentum, and displacement will change continuously.
