The correct answer is The stone tangentially flew away. Tie a stone with a rope and spin it in a circle. While spinning, the rope suddenly broke. Then the stone tangentially flew away.

When a rope is attached to a stone and makes one revolution, what is the work that the rope does to it?

The chords and tangents of the circle will be vertical.So the work done zero.

When a stone with a rope attached to the end of the rope rotates in a circular path, the centripetal force is given by ?

The object is said to be in uniform circular motion. When a stone is attached to the end of a rope and spun, its speed keeps changing direction, but its speed remains the same.The change in velocity is affected by the centripetal force provided by the tension in the string, i.e. mv2r mv 2 r .

What happens to a spinning stone tied with a rope at the end of the rope?

The stone tied to the rope is circled around. As it spins, the rope breaks suddenly.

When the stone is spun once by the rope?

So when an object moves in a circle, there will be centripetal force. Centripetal force acts on the center while tension is a pulling force and it also acts from the stone towards the center. Therefore, the centripetal force will provide the tension of the string.

What keeps the stone in circular motion?

Any object that moves in a circle (or along a circular path) will experience centripetal force. That is, there is some physical force that pushes or pulls the object towards the center of the circle. This is the requirement of centripetal force.

If the rope suddenly breaks, what happens to the stone tied to the end of the rope and spun in a circle, explain why?

What happens to a stone tied to the end of the rope and spun around if the rope suddenly breaks? If the string suddenly breaks, Due to directional inertia, the stone will fly away tangentially in a straight line. This is because the velocity at any point points to the tangent to that point.

Why are rocks tied to small ropes easier to spin than big ropes?

Torque = Force * Vertical Distance

Since torque is proportional to vertical distance, it is clear that the longer the rope, the more torque it will take to rotate it. Therefore, we can conclude that it is easier to rotate the stone by connecting it to a shorter rope.

Why does the stone move away when the rope breaks during the spin?

Answer: When the rope breaks, the stone no longer rotates around its center of rotation, but instead of suddenly moving directly away from it, it will continue to follow its inertial path. That is, it will continue to move in the direction the rope was moving in the moment it broke.

Why does the rope break and the turning stone tied with the rope fly away?

This is because Directional inertia. When the rope breaks, the force acting on the stone ceases. In the absence of force, the stone would fly away in the direction of instantaneous velocity tangent to the circular path.

What is the main force acting on the stone during rotation?

When the stone moves on a vertical circular path, the necessary centripetal force Provided by the tension of the string.

Why do rocks fly away tangentially?

If the rope breaks, the stone will fly away tangentially. why? The velocity of the stone at any moment is along the tangent of the circle at that moment. When the rope breaks, the centripetal force of the rotating stone disappears. Therefore, due to inertia, the stone will fly away tangentially.

Is it centrifugal force?

centrifugal force is External force when the mass rotates. Think of the ball at the end of the rope that is spinning, or the outward movement you feel when the car is turning. In an inertial frame, since the system is not rotating, there is no outward acceleration.

What is the job done by strings?

The work done by the string – definition

In the case of moving the pulley, it Pull double length of rope from both sides Whereas in the case of a fixed pulley, the change in length of the rope on one side can be compensated by the change in the length of the rope on the other side.

When a stone rotates in a horizontal circle, does it indicate that the work is done?

When the stone attached to one end of the rope is rotated horizontally, the rope exerts an inward force on the stone, called nervous. This force provides the necessary centripetal force for circular motion.

Is the speed of the stone uniform?

2) Although The stone rotates at a constant speed, whose direction is constantly changing. Therefore, the stone is said to move with uniform acceleration. The direction of acceleration is towards the center of the circle. …it goes in the opposite direction of the centripetal force, i.e. away from the center.

What force is exerted through the rope?

tension is the force transmitted when a rope, cord, cable or wire is pulled taut by forces acting on both ends. The tension runs along the length of the wire and pulls the object at both ends of the wire evenly.

When an object moves along a circular path, does it have?

A particle spinning in a circular path may have a constant velocity, but changing speed.

When a ball spins in a circle and the string supporting the ball is released, the ball will fly out tangentially This is due to 1 centrifugal force 3 centripetal force 2 inertia of linear motion 4 some unknown reason?

Until the stone is tied to the rope, due to the tension of the rope, it has centripetal and centrifugal forces when it moves in the radial direction, so when the rope is brokenit has no force in the radial direction, so due to inertia, the stone will fly away tangentially.

If the string suddenly breaks, what is the direction of movement of the stone relative to the circular path?

If the rope breaks suddenly, the centripetal force is zero, and only the tangential force exists, then the stone travel in tangential direction.

How is centripetal acceleration derived?

Consider an object of mass m moving in a circle. The radius is r and the velocity is v, as shown. Then, if a small force F is exerted on the object, then we know the force as F=ma. …so the acceleration due to centripetal force is given by,a=v2r.

What causes the barrel to do circular motion?

Like a bucket of water tied to a rope and spun in a circle, Tension on the bucket Provides the centripetal force required for circular motion. As the Moon orbits the Earth, gravity acting on the Moon provides the centripetal force needed for circular motion.

What are your thoughts on circular motion?

Uniform circular motion can be described as object in uniform circular motion. When an object does a circular motion, it constantly changes its direction. … an object in uniform circular motion moves at a constant speed. Still, it’s accelerating due to the change in direction.

Is the acceleration of uniform circular motion constant?

Acceleration is a change in velocity, either in magnitude (i.e. velocity) or direction, or both.In uniform circular motion, the direction of the velocity is constantly changing, so there is always an associated accelerationeven though the speed may be constant.

Why is centrifugal force fake?

Centrifugal force is an outward force obviously in a rotating frame of reference. It does not exist when describing a system relative to an inertial reference frame. …when this choice is made, imaginary forces, including centrifugal force, arise.
