Question

A 1-kg mass at the Earth's surface weighs how much

Answer 1

the answer is weight=10N

Answer 2

`\boxed {\boxed {\sf 9.8 \ Newtons}}`

Step-by-step explanation:

Weight is also called the force of gravity. This force acts on all objects at all times, pulling them down toward the center of the Earth.

It is calculated by multiplying the mass by the acceleration due to gravity.

`F_g=mg`

The mass of the object is 1 kilogram. This scenario is occurring on Earth, so the acceleration due to gravity is 9.8 meters per second squared.

• m= 1 kg
• g= 9.8 m/s²

Substitute the values into the formula.

`F_g= 1 \ kg *9.8 \ m/s^2`

Multiply.

`F_g= 9.8 \ kg*m/s^2`

Convert the units. 1 kilogram meter per second squared is equal to 1 Newton, so our answer of 9.8 kilogram meters per second squared is equal to 9.8 Newtons.

`F_g= 9.8 \ N`

A 1 kilogram mass at Earth's surface weighs 9.8 Newtons.
