Adjusting Speed Variation on Path

You can set position keys on different control points for the prop to approach. You can even set variations in speed for the prop while moving on a path. This can be used to simulate something moving very fast and then very slow or when something is very slow and then enters high speed. There can be a variety of scenarios such as when a person is walking uphill or when a car suddenly goes downhill.

Given an object moving along a path with initial speed as shown below:

The position keys on Timeline was originally like the one in the next illustration:

• Acceleration: Drag to gather the Path Position (%) keys closer to each other to speed up.
  
  Play back to view the result.
  
• Deceleration: Drag to spread the Path Position (%) keys wider to slow down the speed.
  
  Play back to view the result.
