Gravity & Weight Lesson

Multiple Choice

What kind of objects exert a gravitational force

• Objects with volume.

• Objects with mass.

• Objects with weight.

• Objects with colors.

Multiple Choice

Which objects exert a greater gravitational force?

• larger

• smaller

• thinner

Multiple Choice

We only notice the gravitational force of what kind of objects?

• very small

• very dark

• very large

• very light

Multiple Choice

What is the direction of gravitational force?

• away from the center of the object

• toward the edge of the object

• toward the center of the object

Multiple Choice

What happens to the force of gravity as you get further away from an object?

• the force of gravity increases

• the force of gravity decreases

• the force of gravity stays the same

Multiple Choice

Why is the Sun's gravity important?

• It provides light to earth.

• It's not.

• It keeps the Earth and all of the planets in orbit in our solar system.

Multiple Choice

What happens to the force of gravity as you get closer to an object?

• the force of gravity increases

• the force of gravity decreases

• the force of gravity stays the same

Multiple Choice

Mass and weight are the same thing.

• True

• False

Categorize

Options (4)

A measure of gravity's effect on mass.

Measured in kilograms (Kg)

Measured in Newtons (N).

Organize these options into the right categories

Mass

Weight

Multiple Choice

Weight is the result of gravity pulling on an object.

• True

• False

Multiple Choice

A person's mass would be less if they went to the moon.

• True

• False

Multiple Choice

A person's mass would be more if they went to the Sun.

• True

• False

Multiple Choice

A person would weigh less on the moon because the moon's mass is smaller than the mass of the Earth.

• True

• False

Multiple Choice

A person would weigh more on the Sun because the Sun's mass is larger than the mass of the Earth.

• True

• False

Multiple Choice

You can calculate weight using the equation:

Weight (Fg) = Mass (m) × Gravity (g)

Gravity on Earth is 9.8 m/s2

What is the wight of a 15 kg mass on Earth?

• 0.15 N

• 147 kg

• 147 N

• 0.15 kg

Multiple Choice

• Mass

• Weight

• Gravity

• Inertia

Multiple Choice

According to the video, why is the car difficult to LIFT?

• Mass

• Weight

• Gravity

• Inertia

Multiple Choice

What is inertia?

• An object's mass multiplied by the force of gravity.

• A object's resistance to a change in motion.

• An object's force multiplied by its acceleration.
