Work | work=energy transferred work=force x distance j n m |
stretching springs | force(f)=spring constant(k) x extension(x) f k x |
stopping distance ( greater the speed the greater the force to stop) | stopping=thinking + braking m m m |
Resultant force ( if an object is accelerating, there MUST be a resultant force acting on it) ( the picture with the boxes) | resultant force= mass x acceleration n m a |
velocity (the speed in a direction) | change in velocity= acceleration x time |
weight= force of gravity mass= quantity of matter | weight= mass x gravitational field |
speed | distance(m) ----------------- time(s) |
acceleration | change in velocity(m/s) -------------------------------- time taken(s) |
forms of energy | thermal kinetic electric nuclear light sound elastic gravitational |
