An object weighs 500N.what is its mass?

W=mg

W=500N
g= 9.8m/s/s (on the surface of earth)

therefore:
500=m9.8
divide both sides by 9.8
500/9.8=m

m=51Kg

To determine the mass of an object, we can use Newton's law of universal gravitation, which states that weight (W) is equal to the mass (m) multiplied by the acceleration due to gravity (g).

In this case, the weight of the object is given as 500N. The acceleration due to gravity on Earth is approximately 9.8 m/s². By rearranging the formula, we can solve for the mass:

W = m * g

m = W / g

Substituting the given values into the formula:

m = 500 N / 9.8 m/s²

m ≈ 51.02 kg

Therefore, the mass of the object is approximately 51.02 kg.
