A) agility
B) reaction time
C) coordination
D) power
The force acting on the load increases with the length of the lever and distance from the pivot. Thus, option D is correct.
What is the impact of longer the lever on power?The same force can be applied to the longer lever, but the mass will move at a different speed at either end of the fulcrum point. The larger arm moves a longer distance in the same amount of time, while the shorter arm moves a smaller distance.
Its magnitude is (arm) X. (force). The torque grows as the arm is extended while the force remains constant, but as the force travels a greater distance, the work done also increases.
The torque operating on the arm is increased and the arm's resistance to its effects is decreased when the arm's length is halved, increasing the rotational acceleration.
Therefore, The longer the lever, the greater the power.
