Newton's Second Law
Newton's Third Law
Newton's Fourth Law
You are driving to a birthday party with the cake sitting in the passenger's seat. You slam on your brakes to avoid hitting a deer. This causes the cake to splatter all over your dashboard and the floor of the passenger's side. Which of Newton's Laws best explains why this happens?
Newton's First Law (Inertia)
Newton's Second Law (Net force = mass x acceleration)
Newton's Third Law (Action/Reaction)

Newton's 3rd Law of motion states that....
A object in motion/rest stays in motion/rest until it is acted upon by an unbalanced force.
Force is equal to the mass and the acceleration of an object.
For every action there is an equal and opposite reaction.

The nozzle of a rocket is pointed downward so that as fuel is ignited, the exhaust pushes downward. Why is this arrangement necessary for a rocket to function properly?
The rocket is protected from the heat of the exhaust.
Burned fuel can be collected on the ground.
As fuel is combusted, the rocket pushes the gases backward and the gases push the rocket forward.
This allows the rocket to be steered properly.

Blocks 1, 2, and 3
Blocks 1 and 3

Mass will have no affect.
They will accelerate backwards the same.
Person 1 will accelerate more, but both will move.
They will both accelerate back, but person 2 will move more.
