Gravitational Interactions

Why do you think an astronaut can hop so
easily on the Moon while wearing the
heavy suit?

• The astronaut is very strong.

• The suit shrinks on the moon.

• The suit and astronaut have less weight on the moon.

If the surface gravity on Mars is only about 38% of the surface gravity on Earth, would you weigh less or more on Mars than you do on Earth?

• Weigh less on Mars

• Weigh more on Mars

• Weight would not change

According to our gravitational interactions experiment, what is the effect the larger masses had on the washers?

• The larger the mass placed on the string, the less the washers moved towards the mass.

• The larger the mass placed on the string, the more the washers moved away from the mass.
