Which of the following is not an example of perfectly inelastic collision
Updated On: Dec 20, 2025
- A bullet fired into a block if bullet gets embedded into block
- Capture of electrons by an atom
- A man jumping on to a moving boat
- A ball bearing strinking another ball bearing

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Whenever there is a collision between two bodies, the total momentum of the bodies remains conserved. If after the collision of two bodies, the total kinetic energy of the bodies remains the same as it was before the collision, then it a perfectly elastic collision. A ball bearing striking another ball bearing is an example of elastic collision.
If two bodies stick together after the collision, then the collision is said to be perfectly inelastic collision.
Options (a), (b), (c) are examples of inelastic collision

Concepts Used:
Work, Energy and Power
Work:
- Work is correlated to force and the displacement over which it acts. When an object is replaced parallel to the force's line of action, it is thought to be doing work. It is a force-driven action that includes movement in the force's direction.
- The work done by the force is described to be the product of the elements of the force in the direction of the displacement and the magnitude of this displacement.
Energy:
- A body's energy is its potential to do tasks. Anything that has the capability to work is said to have energy. The unit of energy is the same as the unit of work, i.e., the Joule.
- There are two types of mechanical energy such as; Kinetic and potential energy.

Power:
- Power is the rate at which energy is transferred, conveyed, or converted or the rate of doing work. Technologically, it is the amount of work done per unit of time. The SI unit of power is Watt (W) which is joules per second (J/s). Sometimes the power of motor vehicles and other machines is demonstrated in terms of Horsepower (hp), which is roughly equal to 745.7 watts.
- Power is a scalar quantity, which gives us a quantity or amount of energy consumed per unit of time but with no manifestation of direction.
