What is the weight on earth of a person with the mass of 65kg?

The weight of a person with a mass of 65 kg on Earth can be calculated using the formula:

Weight = Mass x Acceleration due to gravity

The acceleration due to gravity on Earth is approximately 9.81 meters per second squared.

So, the weight of a person with a mass of 65 kg on Earth would be:

Weight = 65 kg x 9.81 m/s^2

Weight = 637.65 Newtons (rounded to two decimal places)

Therefore, a person with a mass of 65 kg would weigh approximately 637.65 Newtons on Earth.
