Discovering the Wonders of Physics

Learning Objective

At the end of the lesson you will be able to understand the basics of physics.

This slide will set the learning objective for the lesson.

What do you already know about physics?

What is Physics?

Physics is the scientific study of matter, energy and their interactions.

Introduce the definition of physics and its scope.

Let's Define These Terms

Matter: a physical substance that occupies space.

Energy: the property of matter that has the capacity to perform work (such as causing motion or the interaction of molecules).

Fundamental Concepts

Fundamental concepts in physics include motion, force, energy, and matter.

Introduce the main concepts of physics.

A Few more Terms

Motion: When an object changes its position with respect with time. 

Force: The push or pull on an object that causes it to change its velocity. 

Newton's Laws of Motion

Newton's laws of motion describe the relationship between an object and the forces acting upon it.

Introduce the three laws of motion and explain their significance.

Newton's 3 Laws of Motion

1st Law of Motion: Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

3rd Law of Motion: For each action their is an equal and opposite reaction.

Gravity

Gravity is the force that attracts two bodies towards each other.

Introduce the concept of gravity and its role in physics.

What is gravity?

1. The force that repels two bodies away from each other.
2. The force that causes an object to move in a circular path.
3. The force that attracts two bodies towards each other.
4. The force that causes an object to change its shape.

What is Newton's first law of motion?

1. An object's velocity will change if acted upon by a force.
2. An object's velocity is proportional to the force applied to it.
3. An object at rest or moving at a constant speed in a straight line will remain at rest or keep moving at constant speed unless acted upon by a force.
4. An object's mass will increase if its velocity increases.

What are the fundamental concepts in physics?

1. Light, sound, time, and space.
2. Geometry, algebra, calculus, and statistics.
3. Chemical reactions, cells, organs, and tissues.
4. Motion, force, energy, and matter.

Energy

Energy is the ability of a system to do work.

Introduce the concept of energy and its importance in physics.

Thermodynamics

Thermodynamics is the study of the relationship between heat, energy, and work.

Introduce the basic concepts of thermodynamics and its applications.

Quantum Mechanics

Quantum mechanics is the branch of physics that deals with the behavior of particles at the atomic and subatomic level.

Introduce the basics of quantum mechanics and its relevance in modern physics.
