Question

the weight of a body on the earth's surface​

Answer 1

$\huge \frak \color{red}{answer}$

On the surface of the Earth, it's value is 9.8 meters per square second or 32.2 feet per square second. The weight W, or gravitational force, is then just the mass of an object times the gravitational acceleration.

Answer 2

Answer:

Since g=9.80m/s2 g = 9.80 m/s 2 on Earth, the weight of a 1.00-kg object on Earth is 9.80 N: w=mg=(1.00kg)(9.80m/s2)=9.80N. w = m g = ( 1.00 kg ) ( 9.80 m/s 2 ) = 9.80 N . When the net external force on an object is its weight, we say that it is in free fall, that is, the only force acting on the object is gravity.
