In the video, a man with long hair and a beard is standing in front of a black background. He is wearing a purple shirt and holding a marker in his hand. The man is speaking to the camera while making gestures with his hands. He then starts drawing on the black background with the marker. The drawing is a line that appears to be a part of a larger shape. The man continues to speak and make gestures while the drawing is visible on the screen. The video ends with the man pointing to the drawing and the words \"Inelastic Collision\" appearing on the screen.
