Mastering 90940: A Guide to Demonstrating Understanding of Aspects of Mechanics
Understanding the principles of mechanics is crucial for success in the field of physics. It is also a vital component of the NCEA Level 1 Physics assessment, specifically the accomplishment standard 90940. In this article, we will discuss what this standard entails, the important aspects of mechanics it covers, and how to master this assessment.
What is NCEA Level 1 Physics Standard 90940?
NCEA Level 1 Physics Standard 90940 focuses on testing a student’s ability to demonstrate understanding of aspects of mechanics. It is a multiple-choice examination that is designed to assess the student’s knowledge of the following topics:
• Forces
• Linear motion
• Projectile motion
• Energy
• Heat
The examination comprises of 30 multiple-choice questions and is of an hour’s duration.
Key Aspects of Mechanics
Forces:
One of the fundamental concepts of mechanics, it deals with the interplay between several physical quantities such as mass, acceleration, force, and velocity. The four fundamental forces of nature, i.e., electromagnetic force, gravitational force, strong nuclear force, and weak nuclear force, form a significant part of the forces.
Linear Motion:
The study of the movement of objects in a straight line, linear motion, is another fundamental concept of mechanics. It deals with the velocity, momentum, and acceleration of objects under the impact of different forces.
Projectile Motion:
It is the study of the motion of objects that are projected into the air and are subject to the forces of gravity and air resistance.
Energy:
Energy is the capacity of a system to do work. Kinetic energy and potential energy are two types of energy that are studied concerning mechanics.
Heat:
Heat is the transfer of energy from one body to another due to a temperature difference. It is also a crucial aspect of mechanics.
