Final answer:
The weight of an object on Earth can be calculated using the equation F = ma, where F represents the force of gravity, m represents the mass, and a represents the acceleration due to gravity. For a 65 kg mass, the weight on Earth would be 637 N.
Step-by-step explanation:
The weight of an object can be calculated using the equation F = ma, where F represents the force of gravity, m represents the mass, and a represents the acceleration due to gravity. On Earth, the standard acceleration due to gravity is 9.8 m/s². Given a mass of 65 kg, we can calculate the weight as follows:
F = (65 kg) * (9.8 m/s²) = 637 N.
