Where do the Christoffel symbols come from?

• They are guessed at random
• They fall from the sky
• From the metric

How do you compare vectors at different points?

• Overlap them by eye
• Carry one with the rule
• Vectors can never be compared

A geodesic parallel-transports its own tangent.

Circle one:   True   False

What does the geodesic equation describe?

• A rocket firing its engines
• A free-fall path
• A path that stops at once

Why is the plain component change not enough for a derivative?

• The basis changes too
• Components never change anywhere
• Derivatives are banned in curves

What are the pieces of the geodesic equation?

• Two unrelated constants
• Only the metric alone
• Corrected acceleration

A friend calls any straight-looking coordinate line a geodesic. What is missing?

• Lines must look curvy instead
• It must carry its tangent
• Coordinates decide everything

A freely falling capsule feels no force yet follows a curve in coordinates. Explain.

• Free fall on a geodesic
• An invisible rope pulls it
• Coordinates push all capsules
