Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

4. When only conservative forces are acting on a system, we can use the conservation of energy theorem
to solve a problem. Recall from particle kinetics: T₁ + V₁ = T2 + V2, where V is potential energy (due
to both gravitational and elastic forces: V₂ = Wyc and Ve= + ½ ks², respectively).
The 30-kg rod is released from rest when 0 = 45°. The spring is unstretched when 0 = 45°. Using
conservation of energy theorem, determine the angular velocity of the rod when 0 = 0°.

To understand how the conservation of energy and Newton's second law can be combined to solve kinetic problems. As shown, a large globe has a radius R and a frictionless surface. A small block with mass m starts sliding from rest at the top of the globe and slides along the globe’s surface. The block leaves the globe’s surface when it reaches a height hl above the ground. The system’s geometry is shown for an arbitrary height h. (Figure 1) Note that the subscripts used in this problem is the letter l and not the number 1. Consider what happens when the block leaves the globe’s surface. Which of the following statement or statements are correct? The net acceleration of the block is directed straight down. The component of the force of gravity toward the globe’s center is equal to the normal force’s magnitude. The force of gravity is the only force acting on the block.Consider what happens when the block leaves the globe’s surface. Which of the following statement or statements are…
