Document Summary
Mass: the weight of an object, measure in (kg) Acceleration: pull of earth"s gravity on a kilogram of mass (9. 81m s-2) Force: that what changes or tends to change the state of rest or motion in matter. (also expressed as ) that which changes or tends to change the velocity of an object. Work: force expressed through displacement with no limitation of time. Power: the rate of performing work or the rate of transformation of metabolic potential to work/ and or heat. Velocity: when both speed and direction are specified velocity is being defined. Nm is the effectiveness of a force to produce rotation of an object about an axis, and depends on both the force applied and the distance from the axis of rotation. The information that we have collected in lab regarding the power-velocity characteristics shown in figure 2 tends to follow the correct general trend suggested in today"s literature.
