Weight

Real World Example

Imagine you're trying to carry a backpack filled with groceries up a flight of stairs. Just like how the backpack feels heavier depending on how many items you pack into it, the weight of an object is essentially how much the Earth's gravity is pulling it down. In both cases, the "heaviness" you feel is a direct result of an external force acting on the mass you're trying to lift—whether it's the force of gravity on the groceries or the strain on your arms as you climb the stairs.
