Question

An egg falls from a bird's nest in a tree and feels no effects due to the air. As it falls,only its momentum is conserved.both its kinetic energy and its momentum are conserved.only its kinetic energy is conserved.only its mechanical energy is conserved.both its mechanical energy and its momentum are conserved.

Answer 1

Both the momentum and kinetic energy of the falling egg are conserved.

Step-by-step explanation:

In this scenario, both the momentum and kinetic energy of the falling egg are conserved.

The law of conservation of momentum states that in the absence of external forces, the total momentum of a system remains constant. As the egg falls, its momentum, defined as the product of its mass and velocity, will remain constant throughout the fall.

Similarly, the kinetic energy of the egg is also conserved. Kinetic energy is defined as the energy an object possesses due to its motion. In the absence of air resistance, the egg will not lose any of its kinetic energy, so it will remain constant as it falls.
