How to Calculate Speed and Acceleration

Momentum Momentum = mass x velocity ( Kgm/s ) (kg) (m/s) If an object is moving towards you, your safety will depend on * how massive the object is * how.

Momentum Anything which is moving has MOMENTUM. The amount of momentum it has depends on:- 1. MASS (kg) 2. VELOCITY (m/s)

HOW TO RE-ARRANGE Everyone pick an even number from 6-50 (we will go around room with your numbers)

HOW TO RE-ARRANGE Using those even numbers we will divide them by something easy

HOW TO RE-ARRANGE We get easy fractions…..numbers you probably know how to work in your head

Re-arranging numbers I tend to use my favorite fraction when I re -arrange numbers for speed

#’s in formula have a relationship I tend to use my favorite fraction when I re -arrange numbers for speed

MAIN FORMULAS FOR TODAY 2. MOMENTUM

HOW TO RE-ARRANGE Think of another even number from (6-50)

HOW TO RE-ARRANGE Think of another even number from (6-50) WHERE DOES YOUR # go (top / bottom /side)

HOW TO RE-ARRANGE Think of another even number from (6-50) Does it MATTER what number we divide into your number…..

HOW TO RE-ARRANGE Think of another even number from (6-50) HECK no……as long as it is easy to work with.

Re-arranging numbers I tend to use my favorite multiplication numbers when I re - arrange numbers for momentum problems.

All numbers have a relationship I tend to use my favorite multiplication numbers when I re - arrange numbers for momentum problems.
