Hold the next lower class of qualification A machine lifts a load of 12kN with an applied effort of 4kN. What distance will the load move if the effort moves a distance of 8m and the effici...

vectors - forces with magnitude and direction scalars - forces with magnitude but no direction contact forces - requires contact eg friction non contact forces - doesnt require contact eg gravity mass and weigth - directly proportional weight - mass x gravitational field strength gravitational field strength on earth - 9.81 resultant force - the overal force acting on an object if a resultant force moves and object - work is done scale drawings - triangular drawings, finding the hypoten...

Scalars Quantities that are fully described by a magnitude alone. Vectors Quantities that are fully described by both a magnitude and a direction. Distance Scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement Vector quantity that refers to "how far out of place an object is" it is the object's overall change in position. Speed Scalar quantity that refers to "how fast an object is moving." Velocity V...
