Question

PLEASE GIVE ME ALL FORMULAS OF PHYSICS LESSONS FLOTATION WORK AND ENERGY SOUND

Answer 1

Floatation :
 1. Pressure = Thrust/ Area
 2. Buoyant force = Weight of liquid displaced by the object
                              OR
Weight of object = Weight of liquid displaced by the object.
 3.Density = Mass of the substance/Volume of the substance
4. Relative density of a substance = Density of the substance/Density of water

Work and Energy :
1.Work done = force(F) x displacement(s)
2.Potential Energy =  m g h 
3.Kinetic energy = 1/2mv²
4.Power = work done/time taken
