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.

A person's life was saved in a car accident due to airbags system. During that car accident, airbags expanded in front of head of that person. If that car was not equipped with airbags then movement of head would be stopped by windshield in much faster time. Airbags saved life because it:
A 40kg body starting from rest falls through a vertical distance of 125cm to the ground. The velocity of the body just before it hits the ground is:
An aeroplane is flying horizontally with a velocity of 10 m/s and at a height of 1960 m. When it is vertically above a point A on the ground, a bomb is released from it. The bomb strikes the ground at point B. The distance AB is (ignoring air resistance)
A ball is projected horizontally from the top of a cliff on the surface of the earth with a speed of 40 ms−1. Assuming that there is no air resistance, what will its speed be 3 s later?
A 4 kg body is thrown vertically upward from the ground with a velocity of 5 ms−1. Its kinetic energy just before hitting the ground is
