Physics 4: Mod 1 - Further Mechanics

Nota:

• F=\(\frac{\Delta(mv)}{\Delta(t)}\)

Nota:

• F\(\Delta\)t = \(\Delta\)(mv)

1. Explosions

Nota:

• F=\(\frac{mv^2}{r}\) = m\(\omega^2\)r

Nota:

• \(\omega\) = \(\frac{v}{r} = 2\pi\)f

Nota:

• a = \(\frac{v^2}{r}\) = \(\omega^2\)r

Nota:

• a = \[-(2\pi\f)^2\]x

1. Significance of gradients

Nota:

• T=2\(\pi\) \(\sqrt\frac{m}{k}\)

Nota:

• T=2\(\pi\) \(\sqrt\frac{l}{g}\)

1. Kinetic energy
2. Potential energy
3. Variations with displacement
4. Variations with time
