Thanx! Appreciate that!

You just answered your own question. Work = Force x Displacement (parallel to the force).tubworld said:I agree that it's to have sufficient enrgy to overcome resistance to continue the loop at its highest pt, but what has energy got to do with force? I only remember that force * displacement of force = energy.
The problem tells you the average frictional force is F. So all you need is the distance the block travels in getting up to the top. (Yes... it's half the circumference. It's that simple.)But in this case. the frictional force doesn't travel on a st line, making it hard to calculate the ans. I can't possibly take the diameter as the displacement right? Neither can I take the perimeter of half a circle as the displacement?
Conservation of energy is a fundamental law in physics that states energy cannot be created or destroyed, only transferred or transformed. In the context of vertical circular motion, this means that the total energy (kinetic and potential) of an object remains constant throughout its motion.
As the object moves through its circular path, the conservation of energy states that the total energy (kinetic and potential) must remain constant. This means that as the object moves up and down, its potential and kinetic energies will change, but their sum will remain the same. Therefore, the speed of the object will also change, but its total energy will remain constant.
The radius of the circular path does not directly affect the conservation of energy. However, it does affect the speed of the object, which in turn affects the kinetic and potential energies. A smaller radius will result in a higher speed, while a larger radius will result in a lower speed.
No, the conservation of energy is a fundamental law of physics and cannot be violated. In vertical circular motion, the total energy of the object must remain constant throughout its motion.
The conservation of energy and the concept of work are closely related in vertical circular motion. Work is defined as the transfer of energy from one form to another. In this case, the work done by the gravitational force on the object is converted into kinetic energy as the object moves. The conservation of energy states that the total energy remains constant, so the work done by the gravitational force must equal the change in kinetic and potential energies of the object.
