Answer:

The gravitational force on a mass is its weight. We can write this in vector form, where

w

is weight and m is mass, as

w

=

m

g

.

In scalar form, we can write

w

=

m

g

.

Since

g

=

9.80

m/s

2

on Earth, the weight of a 1.00-kg object on Earth is 9.80 N:

w

=

m

g

=

(

1.00

kg

)

(

9.80

m/s

2

)

=

9.80

N
