To address the student's claim about proving the conservation of mechanical energy using a body falling under gravity, we can break down the explanation step by step: ### Step 1: Understanding Mechanical Energy Mechanical energy is the sum of kinetic energy (KE) and potential energy (PE) in a system. For a body falling under gravity, the total mechanical energy can be expressed as: \[ E = KE + PE \] ...

A baloon filled with helium rises against gravity increasing its potential energy. The speed of the baloon also increases as it rises. How do you reconcile this with the law of conservation of mechanical energy ? You can neglect viscous drag of air and assume that density of air is constant.

Assertion:- A body may gain kinetic energy and potential energy simultaneously. Reason:- Conservation of mechanical energy may not be valid every time.

S_(1): If the internal forces within a system are conservative, then the work done by the external forces on the system is equal to the change in mechanical energy of the system. S_(2): The potential energy of a particle moving along x- axis in a conservative force field is U=2x^(2)-5x+1 is S.I. units. No other forces are acting on it. It has a stable equalibrium position at one point on x- axis. S_(3) : Internal forces can perform net work on a rigid body. S_(4) : Internal forces can perform net work on a non - rigid body.
