Action and reaction in pushing forces
Forces work in pairs. If you push against a wall, the wall pushes with equivalent force back against you. Secure two kitchen spring balances with square platform tops. Put the tops jointly with the dial faces up. Have a pupil push on one whereas you push on the other. Observe that when you push together every balance reads the similar.
Mach number is the ratio of velocity of source to the velocity of sound. Mach Number = Velocity of Source / Velocity of Sound .
For an object moving in uniform circular motion, the direction of the instantaneous acceleration vector is: w) tangent to the path of motion x) equal to zero y)
