Acceleration due to gravity is the rate at which an object increases its speed when falling towards the Earth. It is a constant value that is approximately 9.8 meters per second squared (m/s^2).
Acceleration due to gravity is calculated using the equation a = g, where a is the acceleration and g is the gravitational acceleration constant, which is 9.8 m/s^2 on Earth.
Yes, acceleration due to gravity does change with altitude. As an object moves further away from the Earth's surface, the force of gravity decreases, resulting in a decrease in acceleration due to gravity.
Mass does not directly affect acceleration due to gravity. The rate of acceleration due to gravity is constant for all objects, regardless of their mass. However, a greater mass may require more force to be applied to accelerate it at the same rate as a smaller mass.
The two main factors that can affect acceleration due to gravity are the mass of the objects involved and the distance between them. Additionally, the strength of the gravitational force can also be affected by the presence of other large objects or the shape of the Earth's surface.
