12 standard physics all lesson only formula without explained

Hi

As per your request the formula for the physics in 12th standard are:

Vectors:

Notation: ~a = ax ˆ + ay ˆ+ az

ˆk

Magnitude: a = |~a| =q a2

x + a

2

y + a

2

z

Dot product: ~a ·

~b = axbx + ayby + azbz = ab cos θ

Cross product:

~a

~a × ~b

~b

θ

ˆ

kˆ ˆ

~a×~b = (aybz −azby)ˆ+ (azbx −axbz)ˆ + (axby −aybx)

ˆk

|~a ×~b| = ab sin θ
