A block of mass $0.50 \mathrm{~kg}$ is moving with a speed of $2.00 \mathrm{~ms}^{-1}$ on a smooth surface. It strikes another mass of $1.00 \mathrm{~kg}$ and then they move together as a single body. The energy loss during the collision is (A) $0.16 \mathrm{~J}$ (B) $1.00 \mathrm{~J}$ (C) $0.67 \mathrm{~J}$ (D) $0.34 \mathrm{~J}$

Key Concepts

Kinetic Energy

Kinetic energy is the energy an object possesses due to its motion, calculated by the expression one-half times its mass times the square of its velocity. In collision problems, calculating the kinetic energy before and after the collision provides insight into how much energy is conserved in mechanical form.

Energy Loss in Collisions

Energy loss in collisions refers to the decrease in the total kinetic energy of a system as a result of a collision. In inelastic collisions, a portion of the kinetic energy is transformed into other forms of energy, and quantifying this loss involves comparing the kinetic energies before and after the impact.

Conservation of Momentum

Momentum is the product of an object's mass and velocity, and according to the law of conservation of momentum, the total momentum of a closed system remains constant before and after a collision. This principle is essential in collision problems to determine the final velocities of the colliding bodies when external forces are negligible.

Inelastic Collision

An inelastic collision is a type of collision in which colliding objects coalesce or stick together after the impact. In these collisions, while the total momentum of the system is conserved, kinetic energy is not conserved because some of it is converted into other forms of energy, such as heat or sound.
