Rectilinear Translation-Occurs when all points on a body or object move in a straight line so the direction of motion does not change, the orientation of the object does not change, and all points on the object move the same distance.

Curvilinear Translation-Occurs when all points on a body or object move so that the orientation of the object does not change and all points on the object move the same distance.

What was a marathon runner's average speed in finishing the 42.2 km race in 2 hours 11 minutes? (Ed Eyestone)

A rowing shell was progressing across stream in the Willamette River at 8 mph relative to the water, while the river was flowing at 6 mph. What was the velocity of the shell with respect to the bank? Pacing Example

Displacement with intial velocity and with constant acceleration
d=v_{i}t + 0.5at^{2}

Skeleton Example

A skeleton racers top speed is near 35 m/s (78 mph)
They may feel up to 5G in some turns
Velocity on entering the sled = 5.3 m/s
Acceleration on slope = 1 m/s^{2}

What will the velocity be 3 seconds after entering the sled?

What will the displacement 3 seconds after entering the sled?

What is the average speed if you swim 1500m at 1.46 m/s, bike 40 km at 11.27 m/s, and run 10 km at 5.72 m/s? (2012 Olympic Triathlon)
