9.8 m/s^2
9.8 newtons, down
The gravitational acceleration at the surface of the Earth is 9.8 meter per second per second. To convert between weight (in Newtons) and mass (in kilogram) a factor of 9.8 (or roughly 10) is required.
Both 1 pound of water and 1 pound of steel have the same mass, since they both weigh 1 pound. This is because weight is a measure of the force of gravity acting on an object, while mass is the amount of matter in an object.
Earth pulls on the 1N apple with a force of 1N in the downward direction (towards the center of the Earth) due to gravity. At the same time, the apple also pulls on Earth with a force of 1N in the upward direction (away from the center of the Earth) according to Newton's third law of motion.
A ball thrown parallel to the ground moves downward toward the surface of the Earth because of the force of gravity.
A Newton is the amount of force exerted on one kg of mass at one standard gravity. The common measurement is the pound, which is the pull of the earth on 1 pound of matter. 1 N ≈ 0.225 pound
9.8 newtons, down
A 50-pound would approximately weigh 8.5 pounds on the moon. Moon's gravity is approximately 1/6 of the earth's gravity.
Surface gravity (Earth=1) Mars: 0.38
The gravitational acceleration at the surface of the Earth is 9.8 meter per second per second. To convert between weight (in Newtons) and mass (in kilogram) a factor of 9.8 (or roughly 10) is required.

There are two ways to expand your lungs: 1. Muscles in your chest expand your Rib Cage and pull your lungs outward, expanding their volume. 2. Your Diaphram muscles pull downward and expand your lungs downward.
Both 1 pound of water and 1 pound of steel have the same mass, since they both weigh 1 pound. This is because weight is a measure of the force of gravity acting on an object, while mass is the amount of matter in an object.
Earth pulls on the 1N apple with a force of 1N in the downward direction (towards the center of the Earth) due to gravity. At the same time, the apple also pulls on Earth with a force of 1N in the upward direction (away from the center of the Earth) according to Newton's third law of motion.
On Jupiter, 1 pound would weigh approximately 2.5 times more than it does on Earth. This is because Jupiter's gravity is about 2.5 times stronger than Earth's gravity.
Weight is a measure of the gravitational pull for a mass , such that a mass of 1 Kg is having a weight of 10 Newton . So weight is a downward force measured in Newtons . Weight ( in N ) = Mass ( in Kg ) × Gravity ( usually 10N/Kg )
1. The earth has greater mass 2. the earth is closer to the sun
