Physics - Gravity

What is Physics - Gravity?

Physics - Gravity is a free online course offered by Alison US CA that provides a comprehensive introduction to gravitational forces and their role in motion. Designed for self-paced learning, it covers core principles like Newton’s Second Law of Motion, the universal gravitational constant, and Earth’s gravitational acceleration (‘little g’). The course breaks down complex physics concepts into digestible lessons, helping learners understand how gravity influences object movement and how to calculate related values like velocity and distance over time.

Key features

• Newton’s Laws Explained — Step-by-step breakdown of Newtonian physics fundamentals.
• Gravitational Constant — Learn how 'G' applies across the universe.
• Mass vs. Weight — Clarifies the scientific difference using Earth's gravity.
• Formula Applications — Practice calculating velocity, distance, and time.
• Graphical Analysis — Plot motion data to visualize gravitational effects.
• STEM Foundation — Builds essential knowledge for science, engineering, and math fields.
• Free Access — No cost to enroll with flexible online learning.

Who is Physics - Gravity for?

This course suits high school and college students, aspiring engineers, and lifelong learners interested in physics fundamentals. It’s especially valuable for those preparing for advanced studies or careers in physical sciences, where understanding classical mechanics is crucial. No prior physics expertise is required, making it accessible to beginners.

How does Physics - Gravity compare?

Unlike paid textbooks or university lectures, Physics - Gravity offers a no-cost, structured alternative to learning foundational mechanics. Compared to general science videos, it delivers a certified, curriculum-aligned experience with assessments. While it doesn’t replace lab-based courses, it excels as a theoretical primer and supplements formal education in physics and engineering disciplines.
