What is an invisible force that pulls objects toward each other

• magnetism
• friction
• gravity
• repulsion

What states that every celestial body in the universe attracts every other celestial body

• theory of relativity
• principle of superposition
• university law of gravity

• law of inertia

What is the tendency of an object to remain at rest or in motion until acted upon by an external force

• friction
• acceleration
• inertia
• gravity

how does gravity affect the motion of the solar system

• Gravity keeps the planets in their orbits around the sun.
• Gravity causes the planets to move away from the sun.
• Gravity has no effect on the motion of the solar system.
• Gravity causes the planets to collide with each other.

What makes gravity work with inertia to keep planets and moons in orbit

• Evidence

• Reasoning

• Inertia

• Claim

When you work in a lab and the marble was let go on the fabric without a push the marble went into the sun. where did you learn this

• Evidence

• Reasoning

• Inertia

• Claim

In the solar system, gravity works to pull the planets toward the sun and the moon towards the planets. what is this called

• Evidence

• Reasoning

• Inertia

• Claim

what is the universal law of gravity

• Gravity is a force that pushes objects away from each other.
• Gravity is a force that is stronger for smaller objects and weaker for larger objects.
• Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
• Gravity is a force that only affects objects on Earth.
