I don’t even know really what intertia means let alone moment of it??
Plz help

Newton’s first law of motion can be said as:
>An object will not change its motion unless a force acts on it.
When a force acts on an object, it changes its motion. However, the more inertia the object has, the more force you need to change its motion. This is why throwing a basketball does less damage than throwing a bowling ball.
“Moment of inertia” is also known as angular mass. Mass, the regular one, is a factor in how much force you need to make an object move by pushing it. Angular mass (aka moment of inertia) is a factor in how much torque you need to make an object spin by turning it.
I think the reason they call it the “moment” is because it’s how much force is needed in a single moment, but I really don’t know. Science is full of awful naming choices that confuse people.
