Because if there's no force acting on an object, then the object

continues moving with constant speed in a straight line.

Newton made that simple statement a little over 300 years ago,

and nothing in our everyday experience has ever disproved it.

The force is needed to change the direction of the object's velocity, as it constantly points toward the center of the circle, due to the centripetal acceleration required to maintain circular motion. Without this force, the object would move in a straight line tangent to the circle instead of following the circular path.

The inward force needed to keep an object moving in a circle?

The force that keeps objects moving in a circle is known as the centripetal force, which acts towards the center. The velocity of the object moving in a circle will be tangential to the circle.


What force keeps an object moving in a circle. in what direction does this force act?

The Centripetal force keeps a object moving in a circle and its force and acceleration are directed toward the center of the circle


What is centirpetal force?

Centripetal force is the force that keeps an object moving in a circular path. It acts towards the center of the circle and is necessary to maintain the object's trajectory.


What is the direction of the force that's keeps and object moving in a circle?

The force that keeps an object moving in a circle is directed towards the center of the circle. This force is called the centripetal force and it is responsible for changing the object's direction continuously, keeping it in circular motion.


How does a centripetal force keep an object moving in a circle?

A centripetal force acts towards the center of the circle, continually changing the object's direction towards the center. This force prevents the object from moving in a straight line and keeps it moving in a circular path.


Did you exert a force to keep the stone moving in a circle?

Yes, to keep an object moving in a circle, a force must be exerted towards the center of the circle. This is known as centripetal force.


When an object moves in a circle and acts to accelerate the object toward the center of the circle is what?

The force that accelerates an object towards the center of a circular path is called centripetal force. This force is necessary to keep the object moving in a circle by continuously changing the direction of its velocity. Without centripetal force, the object would continue moving in a straight line tangentially to the circle.


What force keeps an objects moving in a circle?

Centripetal force is the force that keeps an object moving in a circle. It acts inward toward the center of the circle and is necessary to counteract the tendency of the object to move in a straight line due to its inertia.


Why there must be an unbalanced force acting if an object is moving in a circle at constant speed?

An unbalanced force is needed to change the object's direction towards the center of the circle since velocity is a vector quantity that includes both speed and direction. Therefore, the force is required to constantly pull or push the object towards the center of the circle to maintain its circular motion at a constant speed.


What force are holding an object in place as it moves around the circle?

The centripetal force is the force that keeps an object moving in a circular path by pulling it towards the center of the circle. This force prevents the object from moving tangentially and ensures it maintains its circular motion.


What happen if the force acting on an object moving on a circle remove?

If the force acting on an object moving in a circle is removed, the object will continue to move in a straight line tangent to the circle at the point where the force was removed, due to its inertia. This is governed by Newton's first law of motion.


Is force always neede to keep an object moving?

Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
