Position/Displacement

• Vector Representation

Change in Displacement

• Vector Representation
• Computation
• Create displacement versus time graphs
• Change in displacement versus distance
• If given a graph of velocity versus time, use compute the change in displacement over a specific interval

Velocity

• Definition: Rate of change of displacement with respect to time
• Average velocity
• Instantaneous velocity
• When viewing graphs of displacement versus time, be able to:
  • Determine intervals of positive velocity
  • Determine intervals of negative velocity
  • Determine intervals of 0 velocity
  • Create a velocity versus time graph
• Speed: Magnitude of the velocity vector
• Compute velocity using derivatives if given a the displacement of an object as a function of time
• If given a graph of acceleration versus time, compute the change in velocity over a specific interval

Acceleration

• Definition: Rate of change of velocity with respect to time
• Average acceleration
• Instantaneous acceleration
• When viewing graphs of velocity versus time, be able to:
  • Determine intervals of positive acceleration
  • Determine intervals of negative acceleration
  • Determine intervals of 0 acceleration
  • Create an acceleration versus time graph
• Compute acceleration using derivatives if given a the displacement or velocity of an object as a function of time

If you want practice do problems 1, 5-8 after Chapter #8 in Hamill

Uniformly accelerated motion

• Motion where the linear acceleration of the object is constant
• Example is the vertical motion of a projectile - its vertical acceleration is constant and equal to -9.81 m/s2.

Uniform motion

• Motion where the linear acceleration of the object is constant and equal to zero
• Example is the horizontal motion of a projectile - its horizontal acceleration is constant and equal to 0 m/s2.
