Question

An object weighs 490N on earth, find the mass of the object. (b) Write any two differences between mass and weight​

Answer 1

ANSWER:

weight=mg=49

g=10m/s^2

mass , m=49/9.8= 5 kg.

Explanation:

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. ... Weight is mass multiplied by the acceleration of gravity (g).

Answer 2

Explanation:

Weight =Mass×acceleration

Acceleration due to gravity on the earth's surface:

Weight=mg

49N=5×g

g = 9.8 m/s²

Acceleration on the moon=1/6×9.8=1.6333m/s²

The weight on the moon:-5 × 1.6333= 8.1665 N

Answer: 8.1665 N
