How does Newton's third law explain how a rocket will take off?
The rocket doesn't move until ignition
The more mass the rocket has the more force is needs to take off

Velocity
Explain how Newton's second law affects a rocket:
A rocket stays at rest until ignition
Gas pushes down, the rocket goes up
The more mass the rocket has the more force it needs to take off
When a rocket is sitting on a launch pad, what type of energy does it have?
Potential
Kinetic
Gravity
When a rocket is blasting off into space, what type of energy does it have?
Potential
Kinetic
Gravity
Why is it important to have fins on your rocket?
They stabilize the rocket
The reduce drag
They evenly distributes the weight
A rocket is launched into space going 1000m in 20s. What is the velocity of the rocket?
The velocity of the rocket is 50m/s going down.
The velocity of the rocket is 500m/s going up.
The velocity of the rocket is 50m/s going up.
The velocity of the rocket is 50mi/hr going up.
How does Newton's first law explain how a rocket will take off?
The rocket stays at rest until ignition.
The more mass a rocket has the more force is needed to take off.
Gas pushes down, the rocket goes up.
Which of the four forces on a rocket is affected by gravity?
Weight
Thrust
Lift
Drag
What 2 forces does thrust have to overcome for the rocket to be able to take off?
Weight
Thrust
Lift
Drag
What is Newton's Third Law of Motion?
An object in motion tends to stay in motion unless acted upon by an outside force.
Force equals mass times acceleration
An object at rest tends to stay at rest unless acted upon by an outside force.
For every action there is an equal and opposite reaction.
Which of the following statements about drag is incorrect? Drag:
only occurs in a vacuum.
is a force due to friction.
decreases with decreasing speeds.
is due to air resistance.
Drag is to thrust as:
reverse is to forward.
forward is to reverse.
spin is to top.
top is to spin.
