Gravitational Force Practice

as the mass of an object increases, the pull of gravity...

• Increases

• Decreases

• Stays the same

Why do we have a stronger gravitational attraction with Earth than the Sun?

• we are closer to center of Earth

• the Earth has a larger mass than the sun

• we are closer to center of sun

What does the strength of gravity between two objects depend upon?

• Mass & distance
• Mass & weight
• Gravity & inertia
• Inertia & mass

Which of these best describes why your weight (on Earth) would change on another planet?

• Dehydration effects on different planets change weight.
• In general, the smaller the planet, the greater weight
• Different planets have different gravitational pulls
• Weight does not change, no matter where you are.

When placed at equal distances apart, the greatest gravitational attraction will be between two

• skateboards

• bowling balls

• school buses

What is gravitational force?

• It makes objects at rest start moving.
• It makes objects that are moving stop.
• The force of attraction between two objects.
• It pulls you into space.

Which model has greater gravitational attraction (if any)

• Model A
• Model B
• Both Model A and Model B (same gravity)

On which celestial object would you weigh the most?

• Earth
• Jupiter
• Sun
• You would weigh the same on all celestial objects

Why do all of the planets orbit the sun rather than Earth?

• the sun has more mass

• the sun is a star

• the Earth is heavier

• the sun is in the middle of the milky way
