NGSS Science Quiz

What is the first law of Newton's laws of motion, often called the law of inertia?

• Objects in motion remain in motion unless acted upon by an external force.

• For every action, there is an equal and opposite reaction.

• The force exerted on an object is equal to its mass times its acceleration.

• Gravity is the force that attracts a body toward the center of the earth.

Explain how the solar system was formed according to the nebular hypothesis.

• A giant explosion scattered stars into space.

• A large cloud of gas and dust collapsed under its own gravity and began to spin, forming the sun and planets.

• Planets were captured by the sun's gravitational pull as they passed nearby.

• The sun split into smaller parts, which cooled down and became planets.
