Tardigrade Admin · Accepted Answer

Due to internal forces kinetic energy or acceleration of its constituent particle may be non-zero.

Q. If net force on a system is zero then

Its momentum is conserved

Its kinetic energy may increase

The acceleration of its a constituent particle may be non-zero

All of these

Due to internal forces kinetic energy or acceleration of its constituent particle may be non-zero.
