Question Answer
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
