Motion, Forces and Energy
Motion
Energy changes as the trolley Moves across the rough surface
- KE => 0 ; 2. WD against friction 3. KE wasted as thermal Energy
Stability Cariteria 1. The line of action CM must line inside the body., COM: A point where all the mass can be considered to be concentrated

Principle of Conservation of Momentum: {Pi= pf} valid only if Isolated System = > F_net _external to system = 0 : => F_net= Delta P / t FOrces can do 3 things a) Change Shape (configuration) 2. It can change Volume/size 3. It can change the state of motion.
Momentum will change (always if Net Force Acts ) Example: 1. THermal 2. Circular Motion is where P is changing but KE is constant. Force perpendicular to Velicty.
