Newton's Third Law in Space

What is Newton's third law of motion?

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

• An object in motion stays in motion unless acted upon by an external force.

• Force equals mass times acceleration.

• Energy cannot be created or destroyed.

According to Newton's third law, if object 1 applies a force to object 2, what happens?

• Object 2 applies a smaller force back to object 1.

• Object 2 applies a larger force back to object 1.

• Object 2 applies an equal force back to object 1.

• Object 2 does not apply any force back to object 1.

Why did the astronaut not accelerate much when he applied a force to the basketball?

• Because the basketball was too heavy.

• Because the astronaut had a much larger mass than the basketball.

• Because the force was not applied correctly.

• Because there was no gravity in space.

What is the effect of mass on the acceleration of objects when a force is applied?

• Objects with larger mass accelerate more.

• Objects with smaller mass accelerate more.

• Mass does not affect acceleration.

• Both objects accelerate equally regardless of mass.
