Rockets and Newton's Third Law of Motion

What does Newton's First Law of Motion state about an object's state of motion?

• It will always accelerate.

• It will always come to a stop.

• It will remain at rest or in motion unless acted upon by an external force.

• It will change direction randomly.

Which formula correctly represents Newton's Second Law of Motion?

• M = F x A

• A = F / M

• F = M x A

• F = M + A

Newton's third law of motion states that for every action there is an equal and opposite ________.

Which equal and opposite forces are acting on a rocket when it is lifting off the ground? PICK 2

• weight

• thrust

• electricity

• magnetism

How do rockets generate thrust to lift off the ground, based on Newton's Third Law?

• By creating a vacuum in front of them.

• By pushing against the surrounding air.

• By expelling exhaust gases downward, causing an equal and opposite upward force.

• By using magnetic repulsion from the Earth.
