Basic Forces and Newton's Laws

If you travel to Mars, where gravity is 38% of Earth's gravity, what will happen to your mass and weight?

• Your mass and weight will both be greater than on Earth.
• Your mass and weight will both be less than on Earth.
• Your mass will be the same, but your weight will be less than on Earth.
• Your mass will be less than on Earth, but your weight will be the same.

What is the definition of mass?

• Anything that has mass and takes up space.

• The measure of the gravitational pull on an object.

• That amount of matter in an object.

• The amount of space an object takes up.

An astronaut kicks a soccer ball in outer space at a location far from significant influences of gravity and air resistance. The soccer ball will _________.

• continue in motion with the same speed and direction

• eventually stop as its inertia slowly becomes used up

• eventually stop since all objects ultimately "lose their steam"

• either a, b, or c -- depending on whether the astronaut continues to kick it
