Assertion: Mass and energy are not conserved separately, but are conserved as a single entity called mass-energy. Reason: Mass and energy conservation can be obtained by Einstein equation for energy.

Assertion :- Mass and energy are not conserved separately,but are conserved as a single entity called 'mass energy'. Reason :- This is because one can be obtained at the cost of the other as per Einstein's equation.

Which of the following statements is false for collisions- (1)Momentum is conserved in elastic collisions but not in inelastic collisions. (2)Total-kinetic energy is conserved in elastic collisions but momentum is not conserved. (3)Total kinetic energy and momentum both are conserved in all types of collisions (4)Total kinetic energy is not conserved in inelastic collisions but momentum is conserved

(a) Under what conditions energy is conserved ? (b) What is the only restriction to the principle of conservation of energy ?

Assertion : In elastic collision, kinetic energy is conserved. Reason : Energy is always conserved.

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.
