Science Buddies: "Ask an Expert"

My son's science fair project is "Does the Distribution of Mass Affects an Object’s Velocity?" Can someone please help us come up with a catchy or punny title?

Sorry, I'm not an expert but:
"A weighty complication" ?

Hello there
I believe your son's project, The Weighty Impact on Velocity, fits this title. This title reflects the essence of your son's science show project and might generate interest and attention.
