Unit Plan - Introduction to Physics

Unit 1: Introduction to Physics

Unit Objectives:

1. To introduce students to the fundamental concepts and methods of physics.
2. To develop an understanding of the scientific method and its application in physics.
3. To explore the basic principles of motion and kinematics in one dimension.
4. To foster critical thinking and problem-solving skills through hands-on experiments and activities.

Essential Questions:

1. What is physics and how does it differ from other sciences?
2. How do we use the scientific method to explore and understand the physical world?
3. What are the basic principles of motion and how can we describe and analyze them?

Key Concepts:

1. The Nature of Physics
   • Scientific method
   • Units and measurements
   • Vectors and scalars
2. Motion in One Dimension
   • Displacement, velocity, and acceleration
   • Graphical representation of motion
   • Kinematic equations

Key Formulas:

1. Displacement (s)

   $$s=ut+\frac{1}{2}a{t}^2$$

   Where (u) is initial velocity, (a) is acceleration, and (t) is time.

2. Velocity (v)

   $$v=u+at$$

   Where (u) is initial velocity, (a) is acceleration, and (t) is time.

3. Final Velocity (v)

   $$v^2=u^2+2as$$

   Where (u) is initial velocity, (a) is acceleration, and (s) is displacement.
