Hence, the values of g decreases by 4/9 times. The acceleration due to gravity at a height h is: Problem 4: What will be the decrease in the value of g as a body moves a distance of R/2 above the earth’s surface? Solution:

Hence, the acceleration due to the gravity of the body is equal to 0.206 m/s 2. The acceleration due to gravity at the surface of Earth in terms of density is:

Depth: When a body is put inside the earth’s surface the acceleration due to gravity becomes less.Ĭonsider an object of mass m inside the earth of mass M at depth D.

Altitude: When a body moves away from the surface of the earth the force of attraction decreases as the distance between the earth and the body increases.

While the force of gravitation is minimum at the equator of the earth approximately 9.78 m/s 2 as the radius of the earth is maximum at the equator The force of attraction is maximum at the pole of the earth approximately 9.82 m/s 2 as the radius of the earth is minimum at the pole.

The Shape of Earth: As it is known that the shape of the earth is not spherical it’s quite oval so the gravitational force is different at different places.

Here, substitute 6.67 × 10 -11 Nm 2 kg -2 for G, 6 × 10 24 kg for M and 6.4 × 10 6 m for r in the above expression to calculate g at the surface of Earth.įactor affecting acceleration due to gravity

However, if objects are physically larger or take on a flat shape, they will take a longer time to reach the ground due to the effects of air resistance. Therefore, objects of either same or different masses will reach the ground at the same time. However, there are several factors that can impact this occurrence, including air resistance.

Balls with a larger diameter fell more slowly due to a small amount of air resistance that was created during the free fall.Īll objects fall to the ground at the same acceleration, 9.8 m/s/s. It is important to consider that despite the size of the ball, it fell at an acceleration of 9.8 m/s/s due to the effects of gravity. The larger the diameter of the ball, the longer it would take for the ball to fall, while the ball with the smallest diameter fell the quickest. Ultimately, the ball with a greater diameter contributed to a greater degree of friction, which slowed it down compared to the balls with a smaller diameter.

The results demonstrate that while the mass of the ball does not impact the amount of time it takes for the ball to reach the ground, the diameter of the ball has a small impact on this process. Results were collected in an Excel file for further analysis.

Each trial was conducted at least three times. Each ball was dropped from a height of five feet and the amount of time it took to reach the floor was measured using a stopwatch. The weight and diameter of each ball used in the experiment was recorded. I hypothesize that each test ball will reach the ground at the same time because the acceleration due to gravity will act on the objects equally. The purpose of this experiment is to determine the amount of time that it will take for balls of different sizes to reach the ground when they are released from the same height. Despite this, mass is not expected to contribute to the overall acceleration of the object because the acceleration due to gravity will act on the objects equally. Therefore, large, flat objects are likely to exhibit the greatest extent of air resistance while dense, compact objects are less likely to experience this effect. While all objects are known to accelerate downwards at 9.8 m/s/s, the shape of the object has the ability to impact the average velocity of the fall due to the effect of air resistance.
