physics mechanics formula

Before an exam involving physics mechanical formula, recall and write down this acronym/mnemonic. 

Go over it time and time again until it's clearly remembered:

Stupid Decisions Today Can Vastly Affect Future Markets Worldwide Growth.

To remember the meaning of this acronym/mnemonic write the first letters down in this sequence.

What we have is 4 formula pyramids where the letters represent mechanics in physics.

For any physics mechanical formula we have:

1. Distance (m) = Speed (m/s) x Time (s)

`D = S   \text(x)   T`

Or more usually

`\text(Speed) = \text(Distance)/\text(Time)`

2. Change in Velocity = Time (s)  x  Acceleration (m/s²)

`(V - U) = t  \text(x)  a`

Or more usually 

`\text(a) = \text(V-U)/\text(t)`

3. Force (N) = Acceleration (m/s²) x Mass (kg)

`F = a   m`

Or more usually

`F = m   a`

4. Weight (N) = Mass (kg) x Gravity (N/kg)

`W = m   g`
