In this lesson on Conservation of Momentum and Energy in One Dimension, which is part of Unit 3 Area of Study 3 for VCE Physics, you’ll learn how to:
- investigate and apply theoretically and practically the laws of energy and momentum conservation in isolated systems in one dimension.
What is a simple closed system?
A simple closed system is a physical system that does not allow the transfer of matter in or out of the system.
An example of an experiment in a simple closed system is a pulley system. The following video explains this experiment.
What are elastic collisions?
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.
The following three videos go over the types of collisions, and the related calculations required to solve questions.
What are the differences between elastic and inelastic collisions?
An elastic collision is defined as one in which there is no loss of kinetic energy in the collision, while an inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.
In the following videos, we learn about elastic and inelastic collisions and compare the momentum and kinetic energy of each respective collision.
