Both systems shown have massless and frictionless pulleys. On the left, a 10 N weight and a 50 N weight are connected by an inextensible rope. On the right, a constant 50 N force pulls on the rope. Which of the following statements is true immediately after unlocking the pulleys? The 10 N block on the left will have the larger upward acceleration. In both cases, the acceleration of the 10 N blocks will be equal to zero. In both cases, the 10 N block will have the same upward acceleration. The tension in the rope on the left system is 40 N. The 10 N block on the right will have the larger upward acceleratio

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.
