Physics assignment - Essay Example The air opposing the spinning ball causes different air friction at different sides of the ball depending upon the direction of rotation. Due to differing air action on two sides the ball curves towards one side, if a ball is rotating anti-clockwise, the air on its right side causes more impedance because of the ball surface moving against the wind, than on its left side. This is moving in the direction of the wind hence causing the ball to curve towards left. Ball A will travel longer in the air. It happens because the smoothness of the ball causes the air to curve around its surface without creating a lot of resistance during its motion, thus the air drag is low, where as ball B will travel shorter in the air. This is due to the rough surface of the ball that will act as small pockets to the air that is curving around the ball, hence causing air friction on it. This will reduce the energy of ball B greatly. The ball B hence, will travel a shorter distance compared to the Ball A. The S waves travel perpendicular to the direction of the vibration, where as the P waves travel in a direction parallel to the oscillations of the particles. The P waves travel with twice the speed of S waves. The P waves travel in forms of compression and rarefaction zones whereas the S waves travel in form of ripples. The P waves starts forming much earlier than the S
