# Introduction to Newton’s Laws

## Introduction to Newton’s Laws

In this tutorial, we will explore Newton’s three laws of motion and Newton’s law of universal gravitation. We will also learn more about forces and the different kinds of forces. The following provides a summary of the topics covered in this tutorial.

### Different kinds of forces.

The types of forces covered are: normal force, frictional force, applied force and tension.

### Force diagrams and free body diagrams.

In this topic, we will see how to take a problem and draw diagrams to show all the forces acting on a body. We will learn what a force diagram is and what a free body diagram is.

### Newton’s three laws.

Newton’s three laws of motion are discussed in this topic. Each law is covered in detail and practical applications such as rockets, lifts and seat belts are covered.

### Newton’s law of universal gravitation.

This topic explores gravity and Newton’s law of universal gravitation. We will be introduced to the ideas of weight and mass as well as the acceleration due to gravity.

Generally, in this tutorial, we will learn how a net force is needed to modify the motion of an object. We will recall what a force is and learn about how force and motion are related. We are introduced to Newton’s three laws and we will learn more about the force of gravity.
