A man has a mass of 70 kg on earth .Calculate its mass and weight on moon
Moon gravity is only .17 that of earth.
mass-70KG
WEIGHT- 11.2 Newton
The answer is 11.66 kg .
To calculate the mass and weight of a man on the moon, we can use the following formulas:
Mass = Mass on Earth
Weight = Mass on Earth × Acceleration due to gravity on the Moon
1. Mass on the Moon:
The mass of an object remains the same regardless of its location. So the mass of the man on the moon will be the same as his mass on Earth, which is 70 kg.
Mass on the Moon = Mass on Earth = 70 kg
2. Acceleration due to gravity on the Moon:
The acceleration due to gravity on the moon is approximately 1/6th (about 1.622 m/s²) of the acceleration due to gravity on Earth (which is about 9.81 m/s²).
Weight = Mass × Acceleration due to gravity
Weight on the Moon = Mass on the Moon × Acceleration due to gravity on the Moon
= 70 kg × 1.622 m/s²
Calculating the weight on the Moon:
Weight on the Moon = 113.54 N (approximately)
Therefore, the mass of the man on the moon would still be 70 kg, but his weight would be approximately 113.54 Newtons.
