Wednesday was Test Day. Thursday we took notes on Impulse- Momentum Theroem and Conservation of Energy. This next unit is short but sweet, so stay on top of your studies!
Objective: SWBAT understand how momentum factors into car accidents and explore ways that car manufacturers have used the Impulse-Momentum Theroem to reduce injuries from car crashes.
Warm Up: Rhonda (whose mass is 55 kg) is driving 55 mph in her sports car when she crashes into a tree. She is not wearing her seat belt and therefore the steering wheel stops her in 0.01s. Compare the force on Rhonda from this crash to a crash in which her seat belt and an air bag stop her in 0.4 s.
