22. If a man weighs 720 N on Earth, what is his weight on the moon?
120
Acceleration due to gravity on the moon is 1.63 m s^-2
If acceleration due to gravity on the Earth is 9.8 m s^-2 then the weight of the man on the moon is
720 N x 1.63 m s^-2/9.8 m s^-2
To find the weight of the man on the moon, we need to know the acceleration due to gravity on the moon. The acceleration due to gravity on the moon is about 1/6th of that on Earth.
Given that the man weighs 720 N on Earth, we can find his weight on the moon using the formula:
Weight on the Moon = Weight on Earth * (acceleration due to gravity on the moon / acceleration due to gravity on Earth)
Weight on the Moon = 720 N * (1/6)
Weight on the Moon = 120 N
Therefore, the man's weight on the moon is 120 N.
To find the man's weight on the moon, we need to consider the difference in gravitational force between the Earth and the moon.
The weight of an object is influenced by the gravitational force acting upon it. On Earth, the gravitational force is approximately 9.8 m/s^2.
To calculate the man's weight on the moon, we can use the formula:
Weight on the moon = (Gravity on the moon / Gravity on Earth) * Weight on Earth
The gravitational force on the moon is about 1/6th that of Earth, which is approximately 1.62 m/s^2.
Now let's insert the values into the formula:
Weight on the moon = (1.62 m/s^2 / 9.8 m/s^2) * 720 N
Weight on the moon ≈ (0.165) * 720 N
Weight on the moon ≈ 118.8 N
Therefore, the man's weight on the moon would be approximately 118.8 Newtons.
