Gravitational Force and Weight and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Types of Forces I. Gravitational Force and Weight. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • What is gravitational force?
  • What is gravitational field and how does it affect the value of gravitational force?
  • How to calculate the gravitational force at different heights?
  • What is weight and how does it differ from the gravitational force?
  • How does weight and mass differ from each other?

Introduction

Suppose you are resting on a balance. Does the balance show any value?

Now think about this scenario. You attach the balance below your feet and jump from a wall with the balance attached. Does the balance show any value while you are flying?

In the first case, the balance shows a certain value, while in the second, it does not show anything. We will explain the reasons for this in the following paragraphs.

In this tutorial, we discuss two forces that are often confused with each other. They are gravitational force and weight. So, let's see how to deal with them.
