• Gravity is the temperature of an object in space.
• Gravity is the speed at which objects fall to the ground.
• Gravity is a type of energy that repels objects.

Multiple Choice

How does mass affect gravity?

• Mass increases gravitational attraction.
• Mass has no effect on gravity.
• Gravity is independent of mass.
• Increased mass decreases gravitational pull.

Multiple Choice

What happens to gravitational force when the distance between two objects increases?

• The gravitational force fluctuates randomly.
• The gravitational force remains the same.
• The gravitational force decreases.
• The gravitational force increases.

Multiple Choice

Why don’t we feel gravitational pull between small objects, like people?

• We don't feel gravitational pull between small objects because their masses are too small to exert a noticeable gravitational force.
• Gravity is only effective in a vacuum.
• Small objects repel each other due to their mass.
• Gravitational pull is only felt by large celestial bodies.

Multiple Choice

Why do planets stay in orbit around the Sun?

• Planets are held in place by magnetic fields.
• Planets orbit due to their own light.
• Planets are pushed away by solar winds.
• Planets stay in orbit around the Sun due to the gravitational force and their inertia.
