When a stone is projected vertically upwards its kinetic energy changes into potential energy.

A particle is executing simple harmonic motion with frequency f . The frequency at which its kinetic energy changes into potential energy is

A stone is projected vertically up to reach maximum height h. The ratio of its potential energy to its kinetic energy at a height 4/5h , will be

A : The potential energy of a system increases when work is done by conservative force. R : Kinetic energy can change into potential energy and vice-versa.

A stone is projected vertically upward to reach maximum height h. The ratio of its kinetic energy to its potential energy at a height (4)/(5) h, will be

When a body is projected vertically up. At some point P at height h its kinetic energy is twice of potential energy at that point. At what height its potential energy is twice that of kinetic energy?

A particle of mass m is projected at an angle with horizontal with kinetic energy E. the potential energy at the top of its trajectory is E/2 . Find the range.

As an electron makes a transition from an excited state to the ground state of a hydrogen like atom/ion (a) kinetic energy, potential energy and total energy decrease (b) kinetic energy decreases, potential energy increases but total energy remains same (c ) kinetic energy and total energy decrease but potential energy increases (d) its kinetic energy increases but potential energy and total energy decrease

If total energy of the same electron is E, then what would be its kinetic energy and potential energy .
