Question

Point of Release Equilibriumm Position Position Point of Release Which of the following is true for both spheres? The maximum gravitational potential energy is attained as the sphere reaches its point of release. O The maximum gravitational potential energy is attained as the sphere passes through its equilibrium position The maximum kinetic energy is attained as the sphere passes through its equilibrium position. The maximum kinetic energy is attained as the sphere reaches its point of release.

Explanation / Answer

Option (1) and option (3) are the correct.

Explanation -

For the first case, the ball-spring system has ZERO kinetic energy at the point of release because the ball has no velocity. So, the system has maximum potential energy.

Like-wise, in the pendulum system, the ball has MAXIMUM velocity at the equilibrium position so its kinetic energy is MAXIMUM. Potential energy at this point is zero.
