Recap • Last class, we talked about impulse changing momentum. • This class, we are going to talk about what happens if that impulse occurs during 2 scenarios: • When bouncing occurs • When a collision occurs
Notes from last class • Take out your notes from last class and go to the demo section. (Nerf Guns, Ping Pong Balls, Toppling) • You will be shown each demo and give you time to jot down observations.
When is impulse larger? • When objects bounce • When objects don’t bounce • Doesn’t matter either way
Collisions – Today’s activity • Newton’s Cradle – what do you notice? • Observe the cars colliding…What do you notice?
Java Activity • It is your job to complete #1-16; if you have time, you can try your own. • We will recap at the end of the block for a clicker question and to fill in the chart on page 1-2
