To find the force due to gravity on a 41.63 kilogram object, we can use the formula:

```

F = mg

```

where F is the force due to gravity, m is the mass of the object, and g is the acceleration due to gravity.

The acceleration due to gravity is approximately 9.8 meters per second squared on Earth.

```

F = (41.63 kg) * (9.8 m/s²) = 408.9 N

```

Therefore, the force due to gravity on a 41.63 kilogram object is approximately 408.9 Newtons.
