Examples:

1.   If you travel 10m/s due east for 20 s, what is your:

a)   Speed

b)   Displacement

c)   Velocity

2.   If you travel 10m/s due east for 20 s, then you travel 20m/s for 20s due south, what is your:

a)   Speed

b)   Displacement

c)   Velocity

3.   If you travel 10m/s due east for 20 s, then you travel 20m/s for 20s due south, then you travel 10m/s due west for 20s, what is your:

a)   Speed

b)   Displacement

c)   Velocity

1.

a)   Speed (Dist/time) = 200m/20s = 10m

b)   Displacement  200m due east or 0⁰

c)   Velocity = (Disp/time  & Dir) = 200m/20s = 10m @0⁰

2.

a)   Speed (Dist/time) = 200m/20s = 10m

b)   Displacement  200m due east or 0⁰

c)   Velocity = (Disp/time  & Dir) = 200m/20s = 10m @0⁰

3.

a)   Speed (Dist/time) = 200m/20s = 10m

b)   Displacement  200m due east or 0⁰

c)   Velocity = (Disp/time  & Dir) = 200m/20s = 10m @0⁰

 DEMO:

1. Draw a free Body Diagram of this ball on an incline plane.

2. Draw graphs (Pos vs Time, Vel vs Time, & Acceleration vs Time) for a ball rolling down an incline plane
