Can anyone suggest some physics projects on the topics of sound, energy, gravitation or momentum?

for sound + waves :-

demonstration to show propagation of waves , dissipation of energy to the surroundings by waves , experiment to show formation of standing waves , to show resonance (sonometer and resonance tube experiment ) , show dopler effect by creating a siren(like one on ambulance) , project to show formation of pressure/displace waves in organ pipe/flute .

gravitation :-

to show effect of stored potential energy due to gravitational potential energy by setting up a roller coaster course for a small ball , to show working of a weighing machine , to show effect of acceleration due to gravity on the atmosphere(i.e. what should be minimum acceleration due to gravity on a celestial body for existence of atmosphere , so that escape velocity is high enough to prevent smaller particles of gas from escaping the atmosphere ).

momentum :-

the science behind the game of billiards/basketball/cricket(transfer of momentum b/w different bodies) , effect of mass on momentum during collisions , experiment to show transfer of momentum from one ball to another by setting up an apparatus in which each ball is hanged by threads to a rigid support and all are placed close to each other , so that if one ball strikes the second one , the momentum is transfered up-to last ball , and process is repeated .

I agree - something appropriate to billiards might want to likely furnish you with sturdy marks, to boot as a probability to apply each of the matters you reported. artwork, stress, and acceleration = acceleration of the cue ability = Kinetic ability of each of the balls Momentum = transferred from cue to balls, then balls to different balls If I were you, i might want to also locate some coefficient of friction between the table and balls. pretend they are sliding besides the undeniable fact that, not rolling - rolling friction, properly, it really is a lot more suitable complicated.

projects are : to make solar cooker >> to make electric bell using electromegnet solenoid >>

some thing on primary colour of light .. like you can use torch of red , blue & green colour .. as three of torchs will focus on one point u will c white colour >> u could make DNA strand >> to make electrolytic cell >> to determine pH value of different soaps , cold drinks , juices >> tomake wind mill >>
