A person would weigh more on Jupiter than on the Earth because . . .

• Jupiter has more mass, and therefore more gravity
• Jupiter has less mass, and therefore more gravity
• Jupiter has more mass, and therefore less gravity
• Jupiter has less mass and therefore less gravity

How can you explain that we have a stronger gravitational attraction with Earth than the Sun?

• The sun has a larger mass
• The sun has a smaller mass
• Closer to center of sun
• Closer to center of Earth

How is gravity affected by mass?

• the larger the mass of the object, the greater the gravity
• small objects have no gravity
• gravity is not affected by mass of objects, whether large or small

Do planets affect the sun? Why?

• No. Sun pull on the planets and keep them in orbit.
  
• Yes. Sun pulls on planets, planets pull on Sun
