What is Acceleration?

Great video, but you have emphasized a common misconception. WRONG: positive acceleration means speeding up and negative means slowing down. Easy example to show what I mean. When you drop an object it will speed up, but the acceleration on Earth is - 9.8 m/s^2, because the acceleration of gravity is pointing downward in a negative direction. This is a negative acceleration that causes an object to speed up. The misconception comes from the fact that we always teach students that objects are moving in the positive direction. Example that may help: If a sailboat is traveling to the left at - 1 m/s and a gust of wind causes it to speed up to -4 m/s in 6 seconds. The acceleration for this is going to be - 0.5 m/s^2. This lesson will become easier to understand if you introduce vectors and a variety of directions.

Your video is flawless it is so easy to understand a concept which i have been struggling with for 2 years. It overcame my fear of physics now i am starting to love it...
