Ch.2 Physics: Motion along a straight line
- 2.1 Position, Displacement, and avg. Velocity
- Displacement
- delta x= x2-x1
- from position 1 to position 2
- Always a (+) or (-) direction.
- Determined by direction traveling to/away from an orgin
- Vector Quantity:
- When (+) has moved in (+) direction on x-axis
- When (+) has moved in (+) direction on x-axis
- Vector Quantity:
- Determined by direction traveling to/away from an orgin
- Always a (+) or (-) direction.
- from position 1 to position 2
- delta x= x2-x1
- Position
- x
- x
- Average velocity
- What is the difference between average speed and average velocity?
- average speed is always (+)
- shows magnitude
- shows magnitude
- average speed is always (+)
- v(avg)=deltax/deltat
- change in distance over change in time
- Position vs. Time
- m/s
- 2.2 Instantaneous Velocity and Speed
- Instantaneous Velocity
- actually just velocity
- Shrinking time interval closer and closer to 0
- derivative of x(t) graph
- 2.3 Acceleration
- derivative of Velocity graph
- acceleration units
- m/s^2
- m/s^2
- acceleration units
- a (avg)
- 2.4 Constant Acceleration
- Equations for motion
- Only for constant acceleration
- if missing x-xi
- What if we are missing v?
- What if a is missing?
- missing t?
- What if we are missing vi?
- What if we are missing vi?
- missing t?
- What if a is missing?
- What if we are missing v?
- if missing x-xi
- Only for constant acceleration
- Equations for motion
- derivative of Velocity graph
- derivative of x(t) graph
- Shrinking time interval closer and closer to 0
- On graph displacement vs. Change in time
- actually just velocity
- Speed
- Instantaneous Velocity
- 2.2 Instantaneous Velocity and Speed
- m/s
- Position vs. Time
- change in distance over change in time
- What is the difference between average speed and average velocity?
- Avg Speed
- s(avg)= total distance/ change in time
- s(avg)= total distance/ change in time
- Displacement
