When compared to strong nuclear force , gravitational force is

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

c. magnitude and direction
