defence exam SSB Head Constable (Communication) 2023 Mock Test Physics Work Power and Energy Conservation of Mechanical Energy
A particle is thrown at an,angle from the horizontal on earth's surface with an initial velocity u. Then mark the wrong statement assuming zero air resistance:
1
Mechanical energy of the particle is conserved
2
Momentum of the particle is conserved
3
The kinetic energy of the particle is minimum at the highest point
4
The momentum is minimum at the highest point
