# What would happen to an object if the centripetal force acting on it stops?

Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.

### What is the origin of centripetal force?

Centripetal force is the resultant force acting towards the centre of orbit of an object undergoing uniform circular motion.

### Can an object round a curve without any force acting on it?

NO. A force called centripetal force is needed for an object to round a curve.

### How does an object undergoing circular motion behave if the centripetal force force acting it suddenly disappears?

The object will fly out on a angle to the circle.

### What is the centripetal force acting on the moon?

The centripetal force acting on the moon is the gravity from earth.

### What is the centripetal force that causes it to move in a circle?

Any force acting radially from a fixed point is called the centripetal force. Since, the force acts radially therefore it causes the object in a circular path around the centre of force.

### Does centripetal force acting on an object do work on an object?

No 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

### How does Newton's first law and centripetal force relate?

With regard to Newton's First Law only, about all you could say is that if an object has no centripetal force acting on it, then it continues in constant, uniform motion.

### What happen when you apply a force on an object in space?

If it is the only force acting on the object, the object accelerates.

### Centripetal Force is that force which we apply on the object?

Centripetal force is a force that keeps an object inwards, in the case of circular motion or similar.

### What is the acceleration toward the center of a curved or circular path is called what acceleration?

That's called 'centripetal acceleration'. It's the result of the centripetal force acting on the object on the curved path.

### Is a centripetal force an unbalanced force?

Centripetal force acting on an orbiting object is unbalanced since the object is being accelerated. Velocity is continually changing direction if not speed. This means an orbiting object is accelerating and the direction of acceleration is toward the center. In fact, centripetal means "center seeking." A person at rest on the surface of the Earth is being acted upon by a centripetal force (toward the center of the Earth, that is, down) which is exactly… Read More

### What is the force that provides the centripetal force?

It can be a number of different forces- it depends on the situation that the centripetal force is acting in.

### Why is an object in uniform motion experiencing centripetal force?

It's not. If the net force on an object is centripetal, then the object can't move uniformly.

### What happens to the motion of an object tied with a string being whirled in absence of gravitation when the centripetal force acting on it stops and the object is still tied with the string?

the object will go in its tangential direction of that instant. centripetal force pulls the object toward its rotational axis, so if there is no force pulling it inward; inertia will make the object go in the direction it "wants to go" aka- its tangential direction

### What is the net force acting on an object that is not changing speed?

The net force that is acting on an object that is not changing speed is centripetal force that is pulling the object into a circular path. However, just to be clear on this point, while the object's "speed" is not changing, it's "velocity" certainly is, because velocity, unlike speed, has a directional component to it.

### What are the two forces acting upon an object in a circular motion?

There is actually only one force: a centripetal force, that pulls it inward. There can't be a balancing outward force; in fact, if forces were balanced, the object would move in a straight line, not in a circle. Sometimes a "centripetal force" (outward-pulling force) is mentioned, and it can indeed be useful for some calculations, but it is actually a ficticious force.

### What is the reaction force to centripetal force in a centrifuge?

The centripetal force is the force with which the centrifuge pushes some object inwards. The opposite force, of course, is the object pushing the centrifuge outwards.

### What is the direction of the net force acting on an object that is moving in a circle with constant speed?

The net force is called centripetal force and it acts in a direction that is radially inward, always pointing to the center of the circle

### What would happen if you doubled the force acting on a moving object?

If you doubled the force on a moving object you would double its acceleration.

### What is the force that causes an object to follow a circular path?

Newton's Laws of Circular Motion say Centripetal Force is a force which causes an object to follow a circular path. It is proportional to the centripetal acceleration of the object.

### What will happen to an object at rest if it is pushed but there is a large frictional force acting on the object?

It will stay at rest.

### In what direction does centripetal force act on an object?

Centripetal force acts towards the center of the circle of motion.

### Is Centripetal force causes an object to accelerate in a fixed direction true about centripetal force?

Cettripetal Force causes an object to accelerate towards the center. The direction changes as the object moves around the center and is not fixed if the object moves.

### What happens to an object that is moving in a circle if the centripetal force is removed?

The centripetal force is what draws the object towards the centre. The centrifugal force is what draws the object away from the centre. Generally when one speaks of centrifugal force, one means only that it takes the centripetal force to keep moving the object out of its straight direction of travel. If you remove the centripetal force in such an example, such as when the object is in a circular orbit around another body, then… Read More

### What force holds an object in a circular object?

Centripetal force is necessary to keep an object in a circular path.

### What direction is the centripetal force?

Centripetal force is always directed towards the center of the circle of motion that an object is traveling in.

### What is the direction of the centripetal force acting on a body?

Centripetal force always points toward the center of the curved path that the moving body is taking.

### How does centripetal force change the motion of an object?

Centripetal or radial force is a force that is associated with circular motion. Thus centripetal force is a label given to any force, pointed towards the center of circular motion, that alters object's motion so that this object moves in a circle around a centre.

### What would happen if the earth suddenly stops revoving?

When the Earth is revolving a force know as centripetal force is applied on it by the sun or in other words we can say that it is the gravitational pull of sun towards itself and there is another force known as centrifugal force that one feels when traveling a circular path; directed outward, it is actually the inertia of an object that is resisting being pulled in a circular path. when the earth stops… Read More

### What is A 0.25 kg stone tied to a 0.5 m string whirls at a speed of 4 m s What is the centripetal acceleration acting on the stone?

Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2 The centripetal acceleration doesn't depend on the stone's mass. (The centripetal force does.) The centripetal acceleration doesn't "act on" the stone. (The centripetal force does.) The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.

### What is the relationship between centripetal force and mass?

A force which pulls an object toward the center of a circle is called a centripetal force. How much centripetal force needs to be exerted to cause an object to move in a circle? Your experience should tell you that the amount of centripetal force that you need to exert depends on # the mass of the object you are whirling - heavier objects require more force, # how fast you are whirling it… Read More

### What is the relationship between centripetal force and speed?

centripetal force is the object moving in a circular orbit, speed is just how fast it does it

### What will happen to an object in motion with no unbalanced force acting on it?

According to Newton's laws of motion, the object will remain in motion.

### What is a force called that causes an object to move in circle?

A force that causes an object to move in a circle is a central force, or a centripetal force.

### In what direction does the centripetal force act?

Is the direction of centripetal force of an object moving in a circle pointing to the center of the circular path? kk

### Which factor produces Centripetal force?

Any object traveling in a circular path must have a centripetal force on it in order to cause it to curve.

### What will happen if the net force acting on a stantionary object us zero?

It remains stationary

### How does radius speed mass affect centripetal force?

Higher mass means the object needs higher centripetal force Higher mass means higher inertia so the object is more resistant to the acceleration by the centripetal force Higher speed means the object needs higher centripetal force Higher speed means lower friction (or air resistance) that means lower centripetal force is supplied and the object becomes more likely to move in a straight line and break the circular motion and we lose control over it. That's… Read More

### Can a centripetal force ever do work on an object. explain?

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.

### How does it move around the sun?

For object to orbit around the Sun, it required gravitation force from mass of the Sun in balance with centripetal force from velocity of the object. If the gravitation force is too strong then the object would pull down to the sun and if the centripetal force is too great then the object would escape from the orbit.

### What will happen to the acceleration of an object if you double both the mass and the unbalanced force acting on it?

If both the mass and the net force on an object are doubled, then the object's acceleration will not change.
