These two laws lead to the most useful form of the

**formula**for**calculating acceleration**due to**gravity**: g = G*M/R^2, where g is the**acceleration**due to**gravity**, G is the universal**gravitational constant**, M is mass, and R is distance.Likewise, what is the acceleration of gravity in feet per second squared?

An acceleration equal to the acceleration of gravity, 980.665 centimeter-second-squared, approximately

**32.2 feet per second**per second at sea level; used as a unit of stress measurement for bodies undergoing acceleration.What is the acceleration of gravity?

It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of

**gravity**. A free-falling object has an**acceleration**of 9.8 m/s/s, downward (on Earth).What is the speed of gravity in feet per second?

32 feet per second per second

## What is acceleration due to gravity constant include units?

At the surface of the earth this force is a constant per unit mass, and this constant is called the gravitational acceleration, or g, and is approximately

**9.8 m/s**. This constant is defined by the mass and dimensions of the earth and the universal Gravitational Constant.^{2}11

## How do you find the gravitational acceleration of a pendulum?

**Calculate**the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your

**calculated**(T) along with the exact length of the

**pendulum**(L) in the above

**formula**to find "g." This is your measured value for "g." Repeat the above procedure for 3 more cases.
