For circular motion to occur, there must be a centripetal force( a force that is always directed towards the centre of the circle).
The centripetal force is defined as F = mv2/r
Where F is the centripetal force, m is the mass of the orbiting body, v is the velocity of the body, and r is the distance to the centre of the circle.
If you whirl a conker above your head, the centripetal force is provided by the tension of the string. For a planet orbiting the sun, the centripetal force is provided by gravity.
A body moves in a circular path when a centripetal force acts on it, pulling it towards the center of the circle. This force is necessary to keep the body moving in a curved path, as it continuously changes direction. The centripetal force is a result of the body's inertia trying to keep it moving in a straight line, but being redirected towards the center of the circle instead.
A body moves in a circular motion because of the centripetal force acting towards the center of the circle, which keeps the body in its curved path. This force is necessary to counteract the natural tendency of an object to move in a straight line due to inertia.
If there's a body moving in a circle with constant speed, and you come along and do work on it, then either its speed will change, or it will depart from the circle, or both. The force that's keeping it on the circular path is not doing any work on it.
A centripetal force - that is, a force that accelerates the body towards the center of the circle.
The resultant force on a body moving in a circle is directed toward the center of the circle because it is responsible for the centripetal acceleration that keeps the body moving in a curved path instead of a straight line. This centripetal force helps maintain the body's circular motion by constantly changing its direction.
muscles
The heart is the primary force that moves blood through the body. As the heart contracts and releases the blood is then pumped through the vessels that travel to all areas of the body.
The velocity of the body is constantly changing in direction since it is moving in a circle. There is a centripetal acceleration that is always directed towards the center of the circle. The net force acting on the body is towards the center of the circle, providing the centripetal force required for circular motion. The body is in dynamic equilibrium with the centripetal force balancing the outward centrifugal force.
a force, which is the sum total of the two unbalanced forces, acts on the body and the body moves in the direction of the force.
While your speed may be the same, your direction is constantly changing. So there is an angular acceleration. The force caused by this is called centripetal force, and it points towards the center of the circle. You can know this by feeling it, or by drawing a picture of the force system. Acceleration is broken up into normal and tangential components for rotation. The tangential is zero because you are moving at a constant speed, however the normal is not zero, and points to the center of the circle by definition.
A body can execute circular motion only if there's a force acting on it, directedtowards the center of the circle. Without that force, circular motion isn't possible.If you expected us to get into "centrifugal" force, forget about it. No such force exists.
Zero. This is because when a body when around in a circle, a centripetal force acts on the particle to keep it at that fixed distance from the centre. At each point, the force and the displacement are perpendicular to each other. Hence no work is done. The answer is NOT Zero! A Force is required in the direction of motion around the circle. At every point (an infinite number of them) there must be a Force PERPENDICULAR to the Centrifugal and Centripetal Forces or the object would not move. Therefore the amount of work done is the product of that FORCE times the circumference of the circular path, if only considering one revolution.
