∙ 14y agoBy Newton's first law of motion, a force is essential to change the state of rest or of uniform motion along a straight line.
When the body is in the resting position, then a force is necessary to displace it.
When the body is in uniform motion, it means, it has a constant velocity. Velocity is a vector quantity. It has both the magnitude and direction.
If velocity is to be changed then the change can be brought by changing its magnitude or direction or both.
When a body moves along a circular path with a uniform speed, then its direction is changing at every instant. Hence its velocity undergoes a change. Then, according to Newton, there must be a force to bring such a change in velocity. That force is termed as centripetal force which means, the force is always seeking the centre ie directed towards the centre of the circle.
This centripetal if suppose ceases to exist, then the body instead going in the curved path it would go along the tangential path ie straight path with the speed available at that instant.
This centripetal is usually called as necessary centripetal force.
The necessary centripetal force in case of planets going around the sun is provided by the gravitational attraction between the earth and the sun.
In case of electron going round the nucleus, the electrostatic force of attraction between the electron and the protons within the nucleus fulfills the need.
In case of a charged particle going round in a magnetic field, the Lorentz magnetic force plays the necessary role.
In case of vehicle to go round a curved path, the frictional force between the tyre and the ground serves the purpose.
In case of a stone tied to a string making rotation, the tension in the string would be the centripetal force.

The unbalenced force that causes an object to move in a circular path is called a?
centripetal force
What effects gravity and centripetal combined on the same orbiting path?
I'm not sure exactly what you are asking, but centripetal force is just a name given to any force that causes circular motion. Swing a rock on the end of a string and the string tension is the centripetal force. Drive a car around a flat circular track and the friction between the tires and the road is the centripetal force. Put a satellite in orbit and gravity is the centripetal force.
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 is the force called that keeps an object moving in a circle?
The force that keeps an object moving in a circle or an arc is called a centripetal force. Gravity is an example of centripetal force that keeps a satellite in a circular orbit around a planet. Another example is when you ride on a merry-go-round - the rotating play structure imparts a centripetal force upon you, forcing you to also travel in a circle.
The centripetal force that causes circular motion always acts?
Towards the centre of the circle. Centripetal actually means "centre finding".
Is centripetal force a outward force?
No; "centripetal" implies an inward force.
How centripetal force equals to gravitational force?
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.
Can centripetal force produce rotation?
no, but rotation can produce centripetal force
What is the meaning of centripetal force?
Answer It is the force which keeps a body moving in circular motion. Centripetal force is the force that acts opposite to cetrifugal force. Centripetal force is a real force. Centrifugal force is a pseudo-force
Is centripetal force equal to gravitational force in working of a satillite?
The gravitational force IS the centripetal force in this case.
What is a force that holds a moving object in a circular path is called the?

What factors are true about centripetal force?
Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
How does centripetal force affect centripetal force?
Centripetal acceleration is proportional to the square of the speed (a = v2/r). Therefore, according to Newton's Second Law, centripetal force is also proportional to the square of the speed.
What keeps an object in centripetal motion?
The centripetal force
What force acts on a motorcycle riding on the wall of a bowl centripetal or centifugal force?
Centripetal.
How does the centripetal force act on a satellite?
Centripetal force makes a satellite orbit a body.
What is acceleration that occurs in a circular motion?
Acceleration in circular motion is the acceleration directed towards the center of the circle, known as centripetal acceleration. It is responsible for keeping an object moving in a circular path rather than in a straight line. The magnitude of centripetal acceleration is given by the formula a = v^2 / r, where v is the velocity of the object and r is the radius of the circle.
