12 Best Free Online Free Fall Calculator Websites

Check out these best free online free fall calculator websites. Free fall is basically the downward motion of an object under the influence of gravity. The force of gravity exerts a force on the object that accelerate its downward motion. This force is measured as the gravitational acceleration of the body. The gravitational acceleration of Earth is 9.8 m/s². This value is different for different bodies such as Sun, Moon, Mars, Comet, etc. The gravitational acceleration is a crucial factor to determine the other parameters of a free fall scenario.

This post covers 12 websites with free fall calculators. These calculators can help you determine the various parameters of a free fall. All these calculators are pre-configured to work with the Earth’s gravitational acceleration but you can change that value for other scenarios as well. Do note that there are a few assumptions these calculators follow. The falling trajectory of the object is a straight line and there is no friction acting on the falling object. With that said, let’s go through the post and check these calculators in detail.
