If an object weighs 40 n on earth, would it weigh more than 40 n on the moon? explain.

Weight on the surface of moon is smaller than 40 N

Explanation:

As we know that weight is gravitational attraction force of the planet on the objects near the surface of the planet

So we will say

here we know that at the surface of earth the weight is given as

so we have

so when same object is taken at the surface of moon then we will have

since gravity on the surface of moon is smaller than the gravity at the surface of Earth

so weight will be less than 40 N

friction

explanation:

they us to move forward and backwards
