Can centripetal force produce rotation?
Yes, centripetal force is required to maintain rotational motion by pulling an object towards the center of the rotation. Without centripetal force, the object would move in a linear path rather than rotating.
If the radius of rotation and the mass being kept constant how does centripetal force vary with the speed of rotation body?
Centripetal force is directly proportional to the square of the speed of rotation. As the speed of rotation increases, the centripetal force required to keep the object moving in a circular path also increases. This relationship follows the formula Fc = mv^2 / r, where Fc is the centripetal force, m is the mass, v is the speed, and r is the radius of rotation.
If the radius of rotation and the mass being kept constant how does the centripetal force vary with the speed of rotation of the body?
Recall centripetal force = m v^2 / rAs m and r are found to be constants then centripetal force F is directly proportional to the square of the velocity of the body
Is centripetal force a outward force?
No, centripetal force is an inward force that keeps an object moving in a circular path. It is directed towards the center of the circle or the axis of rotation.
Why torque produce by centripetal force is zero?
The torque produced by centripetal force is zero because the force is acting perpendicular to the radius of rotation. Torque is calculated as the force multiplied by the distance from the axis of rotation, and when the force and distance are perpendicular to each other, the torque becomes zero.
Why centripetal force can not produce torque?
Torque is proportional to the distance between the center and the line of force. Centripetal force acts toward the center along the radius, so the distance between the center and the line is zero. (When your car is up on the lift, you can't make a wheel rotate by pushing on the hub.)
What is true about centripetal force Check all that apply.?
Centripetal force always acts inward towards the center of rotation. Centripetal force is required to keep an object moving in a circular path. Centripetal force is a real physical force acting on an object in circular motion. Centripetal force can be provided by tension, friction, or gravitational attraction.
Why work done by centripetal force during half rotation is zero?
The centripetal force always acts perpendicular to the displacement of the object moving in a circular path. Since the work done is the product of force and displacement in the direction of force, and the displacement is perpendicular to the centripetal force, the work done by the centripetal force over a full rotation is zero.
A center-seeking force related to acceleration is force?
F = m * a Force = mass * acceleration
What is the difference between centripetal and centrifugal force?
Centripetal force is the inward force that keeps an object moving in a circular path, while centrifugal force is the outward force that appears to push an object away from the center of rotation.
What is the difference between centripetal force and centrifugal force in physics?
Centripetal force is the inward force that keeps an object moving in a circular path, while centrifugal force is the outward force that appears to push an object away from the center of rotation.
If the magnitude of applied force falls short of required centripetal force then the object will move away from the centre of the circle?
Yes. It would spiral away such that the radius of rotation will increase, until the radius is large enough for the centripetal force to decrease to the applied force. (Centripetal force= mv2/r)
