We reviewed for the test.
Here is the Test Review Question Sheet. I highly recommend doing it. If you can do the Review sheet, you're in good shape for the test. Also, remember to make your NOTE CARDS! Good luck! We learned about the conservation of momentum today. Conservation of Momentum \( \vec{p}_{tot_i} = \vec{p}_{tot_f} \) \( \vec{p}_{1_i} + \vec{p}_{2_i} = \vec{p}_{1_f} + \vec{p}_{2_f} \) \( m_1~ \vec{v}_{1_i} + m_2~\vec{v}_{2_i} = m_1~ \vec{v}_{1_f} + m_2~ \vec{v}_{2_f} \) We talk about Impulse & Momentum today.
Impulse Impulse = \(\vec{F} \Delta t \) Impulse - Momentum Theorem \( \vec{F} \Delta t = \Delta\vec{p} \) \( \vec{F} \Delta t = m \vec{v}_f - m \vec{v}_i \) Group Practice - Impulse We talked about Power and momentum today.
Power \( P = \frac{W_{net}}{\Delta t} \) Momentum \( \vec{p} = m \vec{v} \) Group Practice - Power & Momentum Homework Due 1/9/14 Extended Practice - Work & Energy We reviewed the law of conservation of energy.
Conservation of Energy \(E_{mech_{i}} = E_{mech_{f}} \) \(KE_i + PE_{tot_i} = KE_f + PE_{tot_f} \) Homework GP - Conservation of Energy |
