Question

1. the gravitational force exerted on you by the earth is:

a. your mass
b. your buoyancy
c. your weight
d. too tiny to be measured

1. gravity causes:

a. objects to fall to the ground if nothing is holding them
b. the moon to orbit the earth
c. tides on earth
d. all of the above

Explanation:

• Question 5:
• Mass is a measure of the amount of matter in an object (\(m\)), while weight (\(W\)) is the force of gravity acting on an object (\(W = mg\), where \(g\) is the acceleration due to gravity). Buoyancy is the upward force exerted by a fluid. The gravitational force exerted by the Earth on a person is their weight.
• Question 6:
• Gravity causes objects to fall to the ground when not supported (due to the gravitational pull). It also keeps the Moon in orbit around the Earth (centripetal - like force provided by gravity). Tides on Earth are caused by the gravitational pull of the Moon (and to a lesser extent the Sun) on the Earth's oceans. So all the options A, B, and C are correct, which means option D is correct.

Answer:

• Question 5: C. your weight
• Question 6: D. all of the above
