Which one of the following is true in the case of inelastic collision?
Correct answer: B. Total energy Conserved, Kinetic Energy Not conserved, Momentum Conserved
- A. Total energy Conserved, Kinetic Energy Conserved, Momentum Conserved
- B. Total energy Conserved, Kinetic Energy Not conserved, Momentum Conserved
- C. Total energy Conserved, Kinetic Energy Conserved, Momentum Not conserved
- D. Total energy Not conserved, Kinetic Energy Not conserved, Momentum Conserved
Explanation
Total energy Conserved, Kinetic Energy Not conserved, Momentum Conserved: This is the correct description of an inelastic collision. In a collision, momentum is always conserved. In an elastic collision, kinetic energy is also conserved. In an inelastic collision, kinetic energy is not conserved (it's often converted to heat, sound, or deformation). Total energy is always conserved

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
