Sam weighs 720 N on earth and 120 N on the moon. What does this tell you about the value of gravity on the moon?
To understand the value of gravity on the moon, let's look at the equation for weight:
Weight = Mass x Gravity
Here, Weight refers to the force experienced by an object due to gravity, Mass is the measure of the object's amount of matter, and Gravity represents the gravitational field strength.
On Earth, Sam weighs 720 N. This means that the force of gravity acting on Sam is 720 N. So, plugging this information into the equation:
720 N = Mass x Gravity (Equation 1)
On the moon, Sam weighs 120 N. Now, we can use the same equation and substitute the values:
120 N = Mass x Gravity (Equation 2)
By comparing Equation 1 with Equation 2, we can see that the value of gravity on the moon is less than the value of gravity on Earth. This is because the weight of Sam on the moon is less than his weight on Earth. Thus, the value of gravity on the moon is lower than that on Earth.
