What is the difference between output and input forces

Output Force- the force exerted on an object by a simple machine

Input Force-  the initial force used to get a machine to begin working.

Input Force represents the amount of force that you put into another object. Output Force represents the force that a specific object has as a result of the input force.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
