# Revise smartly with ChatGPT: How to create revision notes

ChatGPT is a powerful tool that makes revising all the easier. Creating revision notes can be tedious, but with this handy tool, you can now make revising smarter!

ChatGPT offers an intelligent and simple way to create revision notes with just a few taps. You don't need to spend hours writing or rewriting content; you can quickly draft and revise your work with ChatGPT.

The prompt below is a reference, you can change the words that are in bold to suit your learning needs.

"I want you to act as an experienced Secondary Physics teacher. Create detailed revision notes for the topic of Newtonian Mechanics. List out the central idea, main branches, and sub-branches. Include all of the key information I need to know. This includes definitions, formulas, and anything else you think will help me in my exam. Make sure I learn about motion and all of its causes.
The topics covered in this section are:

• Kinematics Dynamics,
• Mass, Weight, and Density,
• Turning effect of forces,
• Pressure
• Energy, Work, and Power.

After you are done, create a mermaid mind map that will help me keep track of all that I need to learn. Please try to make the mind map a little more detailed.

### This is how ChatGPT responded

Title: Newtonian Mechanics - Revision Notes

Central Idea: Newtonian Mechanics is the branch of physics that describes the motion of objects and the forces acting upon them. It encompasses various concepts such as kinematics, dynamics, mass, weight, density, turning effect of forces, pressure, energy, work, and power.

### I. Kinematics:

• Definition: Kinematics is the study of motion without considering the causes of motion.
• Key concepts:
1. Displacement (Δx): Change in position of an object.
2. Velocity (v): Rate of change of displacement.
3. Acceleration (a): Rate of change of velocity.
4. Equations of motion:
• $v = u + at$ (final velocity = initial velocity + acceleration × time)
• $s = ut + 0.5at^2$ (displacement = initial velocity × time + 0.5 × acceleration × time^2)
• $v^2 = u^2 + 2as$ (final velocity^2 = initial velocity^2 + 2 × acceleration × displacement)

### II. Dynamics:

• Definition: Dynamics is the study of motion and the forces that cause or change motion.
• Key concepts:
1. Force (F): A push or pull acting on an object.
2. Newton's Laws of Motion: a) Newton's First Law (Law of Inertia): An object at rest remains at rest, and an object in motion continues in motion with a constant velocity unless acted upon by an external force. b) Newton's Second Law: The net force acting on an object is directly proportional to the mass of the object and its acceleration. F = ma c) Newton's Third Law: For every action, there is an equal and opposite reaction.
3. Weight (W): The force experienced by an object due to gravity. W = mg, where g is the acceleration due to gravity.
4. Friction: Force that opposes the motion of an object.
5. Momentum (p): The product of an object's mass and velocity. p = mv
6. Impulse (J): The change in momentum of an object when a force is applied to it for a certain period of time. J = Ft

### III. Mass, Weight, and Density:

• Mass (m): The amount of matter in an object.
• Weight (W): The force exerted on an object due to gravity.
• Density (ρ): Mass per unit volume. $ρ = m/V$, where m is mass and V is volume.

### IV. Turning Effect of Forces:

• Definition: The turning effect of a force, also known as the moment of a force, is its ability to rotate an object around a pivot point.
• Key concepts:
1. Moment of a force (M): The product of the force and the perpendicular distance from the pivot point.
2. Principle of moments: For an object in rotational equilibrium, the sum of the clockwise moments is equal to the sum of the anticlockwise moments.
3. Torque: Another term for moment of a force.

### V. Pressure:

• Definition: Pressure is the force exerted per unit area.
• Key concepts:
1. Pressure (P): Force (F) divided by the area (A) over which it is applied. P = F/A
2. Pascal's principle: Pressure applied to a fluid in a closed container is transmitted undiminished to all portions of the fluid and the walls of the container.

### VI. Energy, Work, and Power:

• Energy (E): The ability to do work or cause change.
• Work (W): The product of the force applied to an object and the distance moved in the direction of the force. W = Fd
• Power (P): The rate at which work is done or energy is transferred. P = W/t, where t is time.

### Mermaid Mindmap (detailed):

Note: The mermaid mindmap provides a visual representation of the topics covered in Newtonian Mechanics, showing the central idea (Newtonian Mechanics) and its main branches (Kinematics, Dynamics, Mass, weight, and density, Turning effect of forces, Pressure, Energy, Work, and Power). Each branch is further divided into sub-branches, ensuring a comprehensive overview of the topic.

### How to use the Mermaid mindmap code given by ChatGPT?

Step 1: Go to this website: https://mermaid.live/.

Step 2: Copy on the 'Copy Code' button located on the top right of the mermaid code provided by ChatGPT.

Step 3: Paste the code in the 'code' section of mermaid.live website.

Step 4: To save this mind map, click on 'Save to Mermaid chart,' create an account, and you will see options to save it.

This is what the saved Mindmap looks like:

As you can see, ChatGPT is an effective tool that simplifies the creation of revision notes, saving you time and effort. However, it's important to note that ChatGPT is not a subject expert, so the information may not be 100% accurate. Therefore, please refer to your textbooks to ensure the accuracy of the information obtained from ChatGPT
