If an object has a mass of 10 kg on Earth, what will its mass be on Jupiter?

• 5 kg

• 10 kg

• 20 kg

• 100 kg

What is the difference between mass and weight?

• Mass is the force of gravity on an object, while weight is the amount of matter in an object.

• Mass is the amount of matter in an object, while weight is the force of gravity on an object.

• Mass and weight are the same and do not change.

• Mass changes with location, while weight remains constant.

How would an object's weight change if it were moved from Earth to the Moon?

• It would increase.

• It would decrease.

• It would remain the same.

• It would become zero.

Which planet has the strongest gravitational pull in our solar system?

• Earth

• Mars

• Jupiter

• Venus
