What are the different types of velocities?
1. Constant Velocity- this type of velocity does not change direction or speed. An object moving at constant velocity would moving in a straight line at a steady speed. An example would be an asteroid or a comet.
2. Changing Velocity- this type of velocity has changes in speed or direction. Either the speed change or direction changes. This type of velocity is also considered to be acceleration
3. Instant (or Instantaeous) Velocity- is an change in direction and speed at a particular point in time. The changes occur at particular points on a graph.
4. Terminal Velocity- is for objects that fall through the atmosphere. This is caused by changes due to air resistance. Gravity takes over and causes the object to accelerate towards the ground.
