All particles in matter are .................. (in constant random motion/at rest always).

The particles are in constant random motion due to

All kinds of matter

Movement of a fly is an example of ...............(mutiple motion/random motion).

What is random motion? Give an example.

The main reason for deviation of gases from ideal behaviour is few assumptions of kinetic theory . These are (i) there is no force of attraction between the molecules of a gas (ii) volume of the molecules of a gas is negligibly small in comparison to the volume of the gas (iii) particles of a gas are always in constant random motion .

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that

A particle is acted upon by a force of constant magnitude which is always perpendiculr to the velocity of the particle. The motion of the particle takes place in a plane. It follows that
