- Chapter 2 - motion forces and newtons laws
- Motion
- Displacement
- Velocity
- Speed = distance / time
- Speed = distance / time
- Acceleration
- Change in velocity / change in time
- Change in velocity / change in time
- Displacement
- Newtons laws
- Law 1 - if an objects force is zero then the object will maintain its velocity forever
- Law 2 - the total force on an object is equal to the sum of all forces on the object
- A = £F/m
- A = £F/m
- Law 3 - if an object asserts a force on a second object the second object exerts a force of the same magnitude in opposite direction
- Law 1 - if an objects force is zero then the object will maintain its velocity forever
- Motion
- Chapter 3 - forces and motion in one dimention
- Motion with constant nonzero acceleration
- Vfx=Vix+a(change in t)
- Change in position=Vix(change in t)+1/2a(change in time)squared
- Vfx squared=Vix squared+2a(change in time)
- Vfx=Vix+a(change in t)
- Normal Forces and Weight
- F=ma
- Free Body Diagram
- Acceleration and Apparent Weight
- ma=+N-mg
- N=mg+ma
- ma=+N-mg
- F=ma
- Adding Friction
- Friction=coefficient of kinetic friction X N
- Friction=coefficient of kinetic friction X N
- Free Fall
- a=Fgrav/m=-mg/m=-g
- v=v+at=Vo-gt
- y=Yo+Vot+1/2at squared=Yo+Vot-1/2gt squared
- a=Fgrav/m=-mg/m=-g
- Cables, Strings, and Pulleys
- Tension Forces
- T=mg+ma
- T=mg+ma
- Tension Forces
- Motion with constant nonzero acceleration
