Understanding Gravity Quiz

What is the definition of gravity?

• A force of attraction between objects due to their mass

• A contact force that only acts on Earth

• A force that repels objects from each other

• A force that only affects objects with no mass

What is the value of the gravitational constant 'g' on Earth?

• 9.8 m/s²

• 10 m/s²

• 8.9 m/s²

• 9.5 m/s²

Which formula represents the relationship for weight?

• W = m + g

• W = g/m

• W = m/g

• W = mg

What happens to objects in free fall in a vacuum?

• They experience the same acceleration regardless of mass

• They do not fall at all

• Lighter objects fall faster

• Heavier objects fall faster

How does air resistance affect falling objects?

• It only affects objects with no mass

• It has no effect on falling objects

• It makes all objects fall at the same rate

• It causes different rates of descent

What role does inertia play in gravitational forces?

• Heavier objects have more inertia, making them harder to accelerate

• Inertia has no effect on gravitational forces

• Inertia only affects objects in space

• Lighter objects have more inertia, making them harder to accelerate

Why is weight less on the Moon compared to Earth?

• The Moon is closer to the Sun

• The Moon has a lower mass

• The Moon has a higher mass

• The Moon has no gravity

What keeps satellites in orbit around Earth?

• The gravitational pull of the Sun

• The gravitational pull of Earth

• The lack of air resistance

• The speed of the satellite

According to the Law of Universal Gravitation, what affects the force of attraction between two objects?

• Both mass and distance

• Only mass

• Only distance

• Neither mass nor distance

What happens to gravitational force if one object's mass is halved?

• The gravitational force decreases

• The gravitational force increases

• The gravitational force remains the same

• The gravitational force doubles
