Gravity is the force that keeps us on the ground and understanding how gravity works is very important as it has a great influence on the upward and downward movement of objects.

This course about gravity will explain Newton’s Second Law of Motion, the universal constant, which is used to work out the force of gravity throughout the universe. You will also learn what the effect of the earth's force of gravity, or little g as it is known, has on an object and why mass is not the same as weight. To fully understand gravity this course will take you step-by-step through the relevant formulas, showing you how to calculate velocity or distance based on time and then plot these changes so you will have a visual concept of what is happening.

This course will be of great interest to students who are studying physics, chemistry, engineering, mathematics, and to students who wish to pursue a career in any of the sciences or engineering fields.

Upon completion of this course you will be able to: - Demonstrate an understanding of the force of gravity; - Discuss why the universal constant for gravity works; - Plot variable against time; - Use the various formulas to solve for an unknown variable; - and convert from mass to weight for any force of gravity.
