Newtons 3rd Law

If the space shuttle has a mass of 1,995,922.5 kg…

1. Calculate the weight of the space shuttle. Use g = 10 m/s/s for your calculations. (Hint: The rule of thumb is 10 N for every 1 kg)

• 19959225 N
• 1995922.5 N
• 19959.225 N
• 1995.9225 N

1. For the space shuttle to accelerate upwards, which force would you need to overcome?

• Gravity
• Friction
• Inertia
• Momentum

Newton’s 3rd Law:

• • For every force on object A, there is an equal and opposite force on object B.

• • All forces occur in pairs

• Energy cannot be created or destroyed, only transformed
• Gravity is a force that attracts two bodies towards each other

According to the 3rd Law of Motion, for every force, there is a response to said force, what is that said equation?

• F=ma
• E=mc^2
• a=v/t
• F=-F

• Your hand hurts after hitting a wall. 

• Or, you push somebody while you’re both in the pool. This would cause you both to move!
  These are examples of with Newton Law?

• Newton's First Law
• Newton's Second Law
• Newton's Third Law
• Newton's Zeroth Law

For the Earth and the moon, the force of gravity works in two directions. Although this is the case, their forces are the same!

• No

• Yes

Suppose a person standing on Earth contemplated the forces acting on them…

What is the action/reaction pair to the force of gravity acting on the person?

• The person's force on the Earth - Support

• The Earth's force on the Moon
• The Earth force on the Person - Gravity

• The Earth's force on the Sun

The force of Gravity and Weight are the same!

• True
• False
• Depends on the context
• Can't be determined

Objects with greater mass experience greater force of gravity!

• True
• False
• Depends on the object's location
• Depends on the object's volume

When Gene Cernan pushed against the spacecraft during his spacewalk:

• both he and the spacecraft moved, away from each other

• He remained stationary
• He was pulled towards the spacecraft
• He moved the spacecraft
