- Part 1
- Momentum
- p=mv
- direction = same as velocity
- Ptotal = sum of all system's momentum
- p=mv
- Impulse
- I=change in P
- direction of impulse is parallel to total force
- I=change in P
- Average Force
- F(change in t) = m(vf-vi) = pf-pi
- direction of impulse is parallel to total force
- F(change in t) = m(vf-vi) = pf-pi
- Momentum
- Part 2
- Conservation of Momentum
- total momentum before collision = total momentum after collision
- total momentum is conserved
- total momentum is conserved
- elastic
- total momentum before collision = total momentum after collision
- Collisions
- elastic
- total initial KE = total final KE
- total initial KE = total final KE
- inelastic
- total initial KE DOES NOT = total final KE
- total initial KE DOES NOT = total final KE
- elastic
- Center of Mass
- balance point of a system
- doesn't have to be the object's center
- balance point of a system
- Conservation of Momentum
- Part 1
- Chapter 8
- rotational motion
- angular position = theta
- angular velocity = omega
- angular acceleration = alpha
- Torque = T
- moment of inertia = I
- angular position = theta
- linear motion
- linear position = x
- linear velocity = v
- linear acceleration = a
- force = F
- mass = m
- linear position = x
- rotational motion
