No Class:  Physics does not meet on Thursday.

29 October 2019:

In Class:  Momentum:

• p = m v
• p = momentum
m = mass
v = velocity or speed
• Impulse:

• J = Fnet t = Δp
• J = impulse
Fnet = net force
t = time
Δ = change
p = momentum
• Expectations:  Students will solve momentum and impulse problems.

Lab 3:
Data collection and analysis of Speeding Cars Lab.

Expectations:  Students will be able to use a spreadsheet to analyze distance and time data and to create graphs to find velocity.
