Why do you need a force to keep a body moving uniformly along a circular path?

Because even though the speed of an object moving in a circular path is constant, its velocity is not. And according to Newton's first law a change of velocity is evidence of a force.
The difference is that speed is just the absolute value of velocity, it just says how many units of distance an object can travel in one unit of time. Velocity on the other hand also contains information about the direction of an object (you can regard it as 3 numbers specifying the speed in x, y and z directions).
And the direction of motion for a body moving in a circular path DOES change even though its speed does not, therefore a force is needed. (The force decreases the speed in one direction and increases it in another).

When an object moves in a circular path a force keeps it moving that way. This force is called force.?
centripetal
When an object moves in a circular path a force that keeps it moving away this force is called?
The Centrifugal force, cDel.P.
A force that holds a moving object in a circular path is called the?
A force that holds a moving object in a circular path is a "centripetal force". In the case of an orbiting planet, moon, artificial satellite etc., the mutual force of gravitation between the orbiting body and the central body is the centripetal force.
What is meant by centripetal force and why does such a force not work in circular orbit?
Centripetal force is the force that keeps an object moving in a circular path. It always acts towards the center of the circle. In a circular orbit, the centripetal force is provided by the gravitational force between the orbiting object and the object it is moving around. If there were no central force, the object would move in a straight line tangent to the circle.
When you observe an object moving in a circle what can you infer about the net force acting on it?
The net force is directed toward the center of the circular path that the object is moving along, and it has a magnitude equal to the velocity squared times mass divided by the radius of the path. (mv^2/r)
CENTRIPETAL?
A force that acts on a body moving in a circular path and is directed around the object which the body is moving
What is centriptal force?
Is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.

What is an inward force on something moving in a circular path?
That is called a centripetal force. Such a force is required for the constant change in direction related to the circular movement (Newton's Second Law).
A force that holds a moving object in a circular path is called the?

What in centripetal force?
Centripetal force is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. It is also known as center seeking force.
