Statement-1: Non zero work has to be done on a moving particle to change its momentum.
Statement-2 : To change momentum of a particle a non zero net force should act on it.

If the resultant force on a system of particles is non-zero, then:

If the resultant force on a system of particles is non-zero, then:

A force of 2 N is applied on a particle for 2 sec, the change in momentum will be

Show that if the force acting on the particle is zero its momentum remains unchaged

Show that if the force acting on a particle is zero , its momentum will remain unchanged.

Statement -1: If kinetic energy of a system is zero then linear momentum of each of particle of the system must be zero. Statement-2: If linear momentum of a system is zero then kinetic energy of system must be zero. Statement-3: If linear momentum of a particle is zero then kinetic energy is zero. Select the correct sequence.

Does a single force acting an a particle necessarily change its K.E. and momentum

Statement-1: Two particles acted by same net force for same time always have same change in kinetic energy. Statement-2: Two particles acted by same net force having same displacement always have same change in kinetic energy.

Statement-1 : The momentum of a particle cannot be changed without changing its kinetic energy. Statement-2 : Kinetic energy (K) of a particle is related to momentum (p) as K=(p^(2))/(2m)
