Hitting the tuning fork causes all the airmolecules around it to vibrate.
This sets up a chain of movement and waves of air molecules stretching out and being compressed.
how to calculate acceleration?
a = v-u/t
distance = u2-v2/2a
renewable energy?
solar energy
geothermal energy
why cant the turbine use all its kinetic energy?
air would start “accumulating” behind the rotor and would start blocking the incoming wind
how does oil improve the efficiency of a bike?
Mechanical devices can be made more efficient through lubrication to reduce the friction between moving parts of a machine and increase the amount of useful energy transferred.
