Forces

Non Contact

Contact

Field Forces

Forces that act by contact

Act in a field that gets weaker over distance

Kinetic Energy

Momentum

Work

Power

Impulse

p = mv

The property of an object in motion

COLLISIONS

InElastic

Elastic

Perfectly

Σ P = (Pfinal - Pinitial)/Efficiency

Σ P = Pfinal - Pinitial

Perfectly

Object stick together but still continue at velocity

Objects bounce off with no energy loss

For Every action there is an equal and opposite reaction force

Force is equal to mass multiplied by acceleration

A object in constant motion or stationary will continue to be so until acted upon by a net force

I= delta p

1/2mv^2 = Ke

Fs=

Delta Ke

Delta W/T=

Watts

Joules

-U=

-(mgh)=

The energy an object has due to its motions

Fv =

Efficiency = Delta Ek/Ek initial

The transfer of energy to an object by froce

F = Delta P/Delta t = Mv/t = Ma

A pull push or twist

Friction

The force produced by collision of particles along surfaces of two objects

Ff=μ x N = μ x mg

Balanced = Continues Velocity or at rest
