Underline the correct alternative :- Work done by a body against friction always results in a loss of its kinetic`//`potential energy.

Underline the correct alternative :- When a conservative force does positive work on a body, the potential energy of the body increases//decreases//remains unaltered .

Choose the correct alternative:- If the zero of potential energy is at infinity, the total energy of an orbiting satellite is negative of its kinetic//potential energy.

Underline the correct alternative :- In an inelastic collision of two bodies, the quantities which do not change after the collision are the total kinetic energy//total linear momentum//total energy of the system of two bodies.

Name the term used for the sum of kinetic and potential energy of a body.

Name the term used for the sum of kinetic energy and potential energy of a body.

Potential energy is the energy possessed by a body by virtue of its:

In deriving Bernoulli's equation, we equated the work done on the fluid in the tube to its change in the potential and kinetic energy. Do the dissipative forces become more important asthe fluid velocity increases ? Discuss qualitatively.

The sign of work done by a force on a body is important to understand. State carefully if the following quantities are positive or negative:- work done by friction on a body sliding down an inclined plane.

In deriving Bernoulli's equation, we equated the work done on the fluid in the tube to its change in the potential and kinetic energy . What is the largest average velocity of blood How in an artery of diameter 2xx 10^-3 m if the flow must remain laminar ? Discuss qualitatively.

A body is thrown vertically upwards with a speed u. When does its potential energy becomes maximum.
