Centripetal force refers to the force that acts on a body moving in a circular path. It does not do work on an object because it acts perpendicular to the motion of the body. The work done on a rotating object is zero.

∙ 13y agoNo because in two cases there is no work done
1. Displacement = 0
2. When there is centripetal force, which is when the displacement and the Force are perpendicular
Only when object is moved up/down in a way then potential energy is gained and potential energy is equal to Work

What is meant by centripetal acceleration is perpendicular to velocity?
As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
What is the differences between an object with no force and an object with zero net force acting on them?
There is nothing different about the two. They both have Notype of differences what so ever. So your question has been answered. Now, will you please, **** off
What is the measurement of the force of gravity pulling an object toward the earth?
The strength of the gravitational forces between the Earth and an object on or near it is called the "weight" of the object. In reality, there are two equal and opposite forces going on. The Earth attracts the object toward it, with a force that is the weight of the object on Earth. At the same time, the object attracts the Earth toward it, with a force that is the weight of the Earth on the object. The forces are equal. When the object is our body, we obsess about the first one. Nobody ever talks about the second one.
What is the practical use of centripetal motion?
Ever used a pushbike? Exactly, Legs on a push bike; reciprocating pistons in engines; heated vapor driven turbines in jet engines. Note in all the examples centripetal motion is a motion, not a force, Isac Newton's human error, he said it was a force, when in reality it is a motion, requiring a force to cause it. A dog on a chain experiences centripetal motion, when it charges out and reaches the end of the chain. but it was the dog, that provided the energey. In a solid universe all motion is a reaction to force, without force nothing can moves, and or if moving stop moving! So there is only one force powerful enough to spin the world, and the planets, if man's theories of multi millions of years of the universes exsitence is TRUTH, and not just thought to be. There has to be a force in The Cosmos, that humans have never comprehended, so they named it God: claimed it to be in their image; thought up actions, and ceramonies of praise, and glorification, to appease it; created beliefs, and theories to explain the actions of this deity! The scriptures, tell it over, and over; Man has never Known the TRUTH!
Why is force needed to keep object moving in a circle?
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.
Why is force centripetal?
Centripetal force is not very difficult to understand, yet most people make it seem overly complex. Centripetal force is an inward force applied to an object that is in circular motion (uniform circular motion). This inward force is what centripetally accelerates an object, which means the object is accelerating around the circle. DO NOT EVER BELIEVE THAT THERE IS A CENTRIFUGAL FORCE. THIS FORCE IS FAKE, BECAUSE THERE IS NO FORCE THAT IS PUSHING OUT ON OBJECT TRAVELING IN UNIFORM CIRCULAR MOTION!!!!!!!!!!!!! All it means is that there is no centripetal force to stop an object from moving out of the circle. An example is a car. If you are sitting in a car, when you go around a bend at a pretty decent speed, you seem to lean in the opposite direction of the turn. this is actually false. you are travelling in a straight line due to your inertia. When the car turns, you continue in that straight line, obviously you don't fly out of the car, because the car applies an inward force on you when you hit the side to keep you centripetally accelerating. Friction is one of the few forces that can stop an object from centripetally accelerating. when i mentioned a straight line due to inertia, I am talking about the velocity of the centripetally accelerating object. This velocity vector is tangent to the circlular path of the object. So that means that if you wanted to whirl a rope over your head like a cowboy and throw a rock at something, you would have to let go of the rope when it was perpendicular to the target. target------------------{((()))}------------------ | | ------- | rock O
What is the different between centrifugal force and centripetal?
Centripetal force is directed toward the center of rotation of an orbiting body or object following a curved path. Centrifugal force is the apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of rotation, caused by the inertia of the body. Whenever you see a moving object that's not traveling in a straight line, you know that a force is acting upon it. That's because objects tend to resist changes to their velocities. The greater the mass, the greater the resistance to changes in velocity. That's called inertia. Objects at rest tend to stay at rest, and objects in motion tend to stay in motion, unless acted upon by some external force. (See Newton's First Law.) Since velocity is a vector -- remember vectors have magnitude AND direction -- any change in an object's direction constitutes a changes in its velocity. When an object is flying around in a circle, its velocity is constantly changing because its direction is constantly changing! That means a force is working on it. That force is the centripetal force, and since force is equal to mass times acceleration, there must be an acceleration involved. You guessed it -- centripetal acceleration. There is a girl on a bike with a jump rope. Her spinning the bike pedals in centripetal force, though her spinning the jump rope around her is centrifugal force. The pedals are designed to keep the motion contained in a small area, keepiing the girl's feet right where they are, but the jump rope lashes out, with the chance of the girl losing her grip on it, due to its force. Centripetal Force is more directed towards the center of the axis of rotation of an object following an elliptical or circular path. Centrifugal Force is the force that pulls away from the center because of the objects inertia. Example: If you took a rock, tied it to a string, and swung it around, the force from the center of the axis of rotation is centripetal force. The force that causes the rock to pull away from the center, is centrifugal force. If you have ever been in a fast moving car that sharply turns and you feel as if you are pulled to the side, that too is centrifugal force caused by your inertia. The more mass the more inertia.

As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
What is the similarities of centrifugal and centripetal force?
Centripetal Force is more directed towards the center of the axis of rotation of an object following an elliptical or circular path. Centrifugal Force is the force that pulls away from the center because of the objects inertia. Example: If you took a rock, tied it to a string, and swung it around, the force from the center of the axis of rotation is centripetal force. The force that causes the rock to pull away from the center, is centrifugal force. If you have ever been in a fast moving car that sharply turns and you feel as if you are pulled to the side, that too is centrifugal force caused by your inertia. The more mass the more inertia. this answer is very good ============================== But largely erroneous. "Centrifugal" force doesn't exist. It's a make-believe, made-up thing, that's not really there. When the centripetal force suddenly shuts off, the object proceeds in a straight line, in the direction it was going at the instant when the centripetal force stopped, and naturally, the straight line takes it straight away from what used to be the center of its motion. We see the object take off straight away from the former center, and we say "Gee, there must be a force pulling it away from there." But there isn't any. That "force" that you think you feel when the car turns a corner and you get pressed against the door, away from the curve ? That's just the tendency of your body to want to keep moving in a straight line, and its reaction to the centripetal force that the car-seat and the door are exerting on you in order to make your body move in a curved path. There is no "centrifugal" force.
What is the measure of the gravitational force on an object called?
If the object is on or near the Earth's surface, then most people call that force the object's "weight". Nobody ever gives any attention to the gravitational force that the object exerts on the Earth, probably because it happens to be exactly the same as the object's weight on the Earth. The neat thing about it, however, is that the same force is also the Earth's weight on the object.
What causes the planets and moons to rotate?
The force of attraction of the central mass (star or planet) and high velocity of moving body, the central attraction works as centripetal force and velocity of moving body acts as centrifugal force, where these forces are balanced the body rotates for ever.

Can a small force produce a greater torque than a large force?
Can a small force ever exert a greater torque than a larger force? Explain yes it is possible if small force is applied with a larger moment arm(lever arm) as compared to larger force.
How can you use newtons first law to explain why centrifugal force does not exist?
you cant.... think about it when ever you spin in a circle you are pulled outwards...
