Gravity and Mass

How does the mass of an object impact gravity?

• The more mass an object has, the stronger the gravity.

• Gravity is only affected by the shape of an object, not its size.

• Gravity is inversely proportional to the size of an object.

• The size of an object does not impact gravity.

An average bowling ball has a mass of 7.26 kilograms. On Earth, it would weigh 16 pounds. On the moon, where the force of gravity is much weaker, the ball’s mass would still be 7.26 kilograms. However, because gravity isn’t pulling it down as strongly, it would weigh only 2.65 pounds. Which of the options listed below would be true if you stood on the moon?

• your mass would increase

• you would weigh more than you do on Earth

• you would weigh the same as you do on Earth

• Your same mass would stay the same

Which of the following never changes no matter where in the universe?

• weight

• force

• mass

• pounds

What makes mass and weight different?

• Mass is the amount of matter meanwhile weight is expressed in kg, lbs. and g.

• Mass and weight are expressed in g, kg and lbs.

• Mass is the amount of matter meanwhile weight is the force of gravity on an object's mass.

• none of the choices

If an object mass =30 Kg on the Earth, what would be it's weight on Earth?

• 30 N

• 300 kg

• 3000N

• 300 N
