What you'll learn

  • Understand the basic elements of physics and their foundation in calculus
  • Practice mathematical calculations with large numbers
  • Develop an understand for the laws of physics through examples of their application in the world of nature and technology
  • Differentiate and derive units

Course content

1 section • 17 lectures • 1h 35m total length

  • The potential energy of gravity - less than zero3:07

    The lecture shows gravitational potential energy is negative, with zero at infinity and Earth's surface as the reference, and that energy increases as distance grows.

  • Gravitational interactions – magic of weight.6:36
  • The first cosmic velocity is about placing satellites in orbit.4:39
  • The third Kepler’s Law - communication with satellites and geostationary orbit.6:30
  • The second cosmic velocity- escape velocity.5:20
  • Earth orbit - facts about LEO, MEO and GEO.5:51
  • Weightlessness and Overloading-Riding in a Lift.4:09
  • Acceleration of gravity and the weight of objects (Part 1).4:54
  • Acceleration of gravity and the weight of objects (Part 2).5:22
  • Acceleration of gravity and the weight of objects (Part 3).4:16

    Explore how gravity and centrifugal force from Earth's rotation shape weight on the surface. Learn why the Earth bulges at the equator and why gravity varies from pole to pole.

  • Acceleration of gravity and the weight of objects (Part 4).3:39

    Explore how Earth's rotation creates a non inertial frame where gravity is opposed by centrifugal force, yielding gravity at the poles (9.83 m/s^2) and at the equator (9.78 m/s^2).

  • The effects of gravitational interactions - tides in an ideal atmosphere.6:28
  • Acceleration of gravity inside and outside of planets.6:38
  • The intensity of the gravitational and electrostatic fields – Let’s draw a sun.8:25
  • Gravitational and electromagnetic fields - at the crossroads of interaction.6:24
  • Gravitational and electrostatic effects in the atom – examples.3:10
  • Projections -description of motions near the surface of the Earth.10:17

Requirements

  • High school-level math and algebra
  • A basic knowledge of equations of motion and dynamics

Description

This course in physics explains gravitational interactions. In these lessons, you will learn everything about the law of universal gravitation, its relationship with the laws of dynamics, the Third Law of Kepler, and you will understand why gravitational forces are the weakest that exist in our natural world. This course includes the derivation of all formulas with step-by-step unit conversions and values. Each topic is explained using detailed examples with helpful animations.

Who this course is for:

  • Any student enrolled in a high school physics course
  • Anyone wishing to further their knowledge of physics
