1. F Mass, Weight and Gravity (A) Name: ______________________ m g
____________________ is the amount of matter in an object. It is not related to gravity.
It does not change when you move (from Earth to the moon, for example).
____________________ is a type of force commonly measured in Newtons. It
DOES change when you move from Earth to the moon, because of a different
Amount of gravity.
____________________ is the force that causes all masses to attract each other.
Remember: the “full name” for “N” is kg * m/s2.
For all questions, show your work, and round final answers to the tenths place. F m g
Formulas:
F = m x g
M = F/g
G = F/m
Your Physics textbook has a mass of 2.2 kg. What is its weight on Earth?
An astronaut weighs 104 N on the moon, where the strength of gravity is 1.6 m/s2. What is her mass?
Of all the planets in the solar system, Jupiter has the greatest gravitational strength. A 0.5 kg shoe weighs N on Jupiter. What is the gravitational strength there?
4. A tractor-trailer carrying boxes of rubber ducks stops at a weigh station on the highway. The truck weighs 160,000 N. What is the mass of the truck?

5. A tractor-trailer carrying boxes of rubber ducks stops at a weigh station on the highway. The truck weighs 180,000 N. What is the mass of the truck?
6. If your purse has a mass of 3 kg, it has a weight of 19.6 N on Venus. What is the strength of gravity on Venus?
Your backpack is giving you a backache. You measure it on a scale, and find that it weighs 400 N. What is its mass?
8. An astronaut weighs 1000 N on Earth. What does he weigh on the moon (g = 1.6 m/s2)?
