Just to make sure, what is the difference between changing the direction of velocity and changing the direction of acceleration? Can anyone answer, please?
When you throw a ball upwards, then at the top of the trajectory the direction of velocity changes, but the direction of the acceleration stays the same.Sundown444 said:Just to make sure, what is the difference between changing the direction of velocity and changing the direction of acceleration?

If you go from pushing the accelerator pedal to pushing the brake pedal, the direction of the car's velocity doesn't change, but the direction of the car's acceleration changes.Sundown444 said:can you please give me another example?
