# Energy, Momentum, and Mass

Students examine data to find how energy, momentum, and mass are related.

# The Case of the Hidden Neutrino

Students use momentum conservation to examine the decay of top-antitop pairs to determine what is missing from the event.

# Mean Lifetime Part 2: Cosmic Muons

Students learn how physicists measure muon lifetime.

# Calculate the Top Quark Mass

Students use conservation laws and vector addition to calculate the top mass from event displays.

# Calculate the Z Mass

Students use conservation laws and vector addition to calculate the Z mass from event displays.
