Lesson: The Relationship between Mass and Weight Physics • First Year of Secondary School

In this lesson, we will learn how to apply Newton’s second law of motion to define gravitational field strength as the force acting on an object per kilogram of its mass.

Lesson Plan

Students will be able to

identify weight as a force that acts on an object with mass in a gravitational field,
recognize that acceleration due to gravity in meters per square seconds (m/s²) is equal to gravitational field strength in newtons per kilogram (N/kg),
calculate weight forces where acceleration due to gravity may vary,
recognize that variation in weight due to variation in acceleration due to gravity does not involve variation in mass.
