A particle that has zero momentum must also have zero kinetic energy. True False
Utkarsha H.
Statement 1 If the speed of a particle is $2 \mathrm{~m} \mathrm{~s}^{-1}$, the magnitude of its linear momentum (in $\left.\mathrm{kg} \mathrm{m} \mathrm{s}^{-1}\right)$ is numerically equal to its kinetic energy (in joule), irrespective of the mass of the particle. and Statement 2 Mass of a particle is equivalent to energy (in joule).
1.) If the momentum of a single particle is zero, its kinetic energy may not be zero. 2.) The linear momentum of an object is proportional to the mass of the object. 3.) The momentum of an isolated system is always conserved no matter what kind of force is acting inside the system. 4.) If two particles of different masses have equal kinetic energy they also have equal momentum. 5.) The kinetic energy is always conserved both in elastic collisions and inelastic collisions. 6.) A large force always produces a larger impulse on a body than a smaller force. 7.) If the kinetic energy of a single particle is zero, its momentum must be zero. True or false.
