ACCELERATION DUE TO GRAVITY
Learning Outcomes
*Understand the meaning of acceleration due to gravity and know its value is 9.8 m/s² near the Earth’s surface.
*Students will recall the formula:g=GM/R^2
*Students will be able to explain that acceleration due to gravity is independent of mass of the falling object.
Acceleration due to gravity:-
Acceleration due to gravity is the rate at which an object speeds up as it falls toward the Earth. This happens because the Earth pulls everything toward its center through a force called gravity. When you drop something, it doesn’t fall at a constant speed. Instead, it gets faster every second.
•When something falls, it gets faster and faster because the Earth pulls it down.
•This pull is called gravity.
•The speed increases at a rate of 9.8 meters per second every second (9.8 m/s²).
