Which formula is used to calculate the mass of an object if the force and acceleration are known?

For this case we have by definition, Newton's second law of motion states that the force is directly proportional to the mass and to the acceleration of a body. That is to say:

Where:

F: It's the strength

m: It's the mass

a: It's the acceleration

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
