The document discusses the formula for kinetic energy, defined as (1/2)mv². It establishes that at maximum velocity, the total energy equals kinetic energy, leading to the equation e=(1/2)m(vmax)². Additionally, it connects this with simple harmonic motion, expressing vmax as aω and providing a derived formula for energy in terms of amplitude and angular frequency.

7. Kinetic Energy= (1/2)mv2
At maximum velocity, the total
amount of energy is equal to
kinetic energy.
Therefore, E=(1/2)m(vmax)2
From SHM, vmax=Aω
Hence, E=(1/2)m(Aω)2
E=(1/2)(ρV)(Aω)2
