High School Physics: Force and Energy is a free online course that introduces you to the standards and applications of work and energy. Work and Energy play an essential role in our everyday lives and scientific circumstances. When a force acts upon an object to cause a displacement of the object, it is said that work has been done on the object. There are three key ingredients to this which are workforce, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement. There are several good examples of work that can be observed in our everyday life. From a horse pulling a plow through the field, a father pushing a grocery cart down the aisle of a grocery store, a student lifting a backpack full of books upon his shoulder, and a footballer kicking a ball, etc. In each case described here, there is a force exerted upon an object to cause that object to be displaced.
The course begins by introducing you to Newton's laws and forces and Kepler's three laws of planetary motion. Sir Isaac Newton worked in many areas of mathematics and physics. He developed the theories of gravitation in 1666. In 1686, he presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis.” By developing his three laws of motion, Newton revolutionized science. Newton’s laws together with Kepler’s Laws explained why planets move in elliptical orbits rather than in circles. The course then analyzes friction, the general characteristics of friction, and the coefficient of friction. The applications of friction can be seen in our everyday activities. It is an important factor in many engineering disciplines like transportation, measurement, and household usage. For example, road slipperiness is an important design and safety factor for automobiles or the use of a tribometer to measure the friction on a surface. You will learn about the different applications of frictions and how to reduce it.
Lastly, you will be introduced to Momentum. Momentum is a commonly used term in sports. Momentum is a physics term; it refers to the quantity of motion that an object has. A sports team on the move has momentum. If an object is in motion (on the move) then it has momentum. The course analyzes the conservation of momentum problems and the momentum theorem. Work, in physics, is the measure of energy transfer that occurs when an object is moved over a distance by an external force applied in the direction of the displacement. The course identifies the different kinds of situations where no work is done. So, register for this course and begin your next learning journey!Start Course Now
