Answer :
The Newton's Cradle is an apparatus that uses spheres in motion to show how momentum and energy are conserved.
Describe momentum.
- Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum. Check out Newton's laws of motion.
- According to Newton's second law, if a particle is subjected to a constant force for a specific amount of time, the result of the force and time (referred to as the impulse) is equal to the change in momentum. On the other hand, a particle's momentum represents the length of time needed for a consistent force to bring it to rest.
- Any grouping of particles has a momentum equal to the vector sum of its individual momenta. A change in one particle's momentum is precisely balanced by an equal and opposite change in the momentum of another particle, according to Newton's third law, which states that particles exert equal and opposite forces on one another.
