Conservation Of Mechanical Energy

STATEMENT -1 : The escape valocity upon Earth's surface is 11.2 km/s. But velocity required for escaping is little less than 11.2 km/s if launched properly. and STATEMENT -2 : Escape velocity is independent of angle of projection. Conservation of mechanical energy uses KE and GPE which are scale quantities.

Define mechanical energy and law of conservation of mechanical energy. Prove conversion of gravitational potential energy in to kinetic energy by the help of law of conservation of mechanical energy. Also draw graph between energy and height.

Explain the conservative of mechanical energy for a free fall body .

Assertion: According to law of conservation of machainical energy change in potential energy is equal and opposite to the change in kinetic energy Reason: Mechanical energy is not a conserved quantity.
