According to Newton’s first law of motion, when will an object at rest begin to move? when its inertia decreases to zero when an unbalanced force acts upon it when the action and reaction forces are equal when two equal and opposite forces act upon it

Option b

Explanation:

This is a nice and simple question!

Consider Newton's first law of motion. It states that an object at rest will remain at rest until acted upon by an unbalanced force. That being said the reverse is applicable as well, an object in motion will remain in motion unless acted upon by an unbalanced force.

Thus, according to Newton's first law of motion, an object at rest begins to move when an unbalanced force acts upon it.

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
