What is the force of gravity on earth?
The force of gravity on Earth is commonly referred to as the acceleration due to gravity, which is approximately 9.8 meters per second squared (9.8 m/s²). This means that for every second an object falls, its speed increases by 9.8 meters per second.
To find the force of gravity on Earth, we can use Newton's second law of motion, which states that force (F) equals mass (m) multiplied by acceleration (a):
F = m * a
In this case, the force of gravity (F) is the weight of an object, the mass (m) is the object's mass, and the acceleration (a) is the acceleration due to gravity. Therefore, the formula can be written as:
Weight = mass * acceleration due to gravity
On the surface of the Earth, the acceleration due to gravity is approximately 9.8 m/s². So, if we know the mass of an object, we can calculate its weight by multiplying it by 9.8.
