Which fictitious forces?

the ones that arise when you set your reference frame on top of an accelerating object.

e.g. when you're in a car and you seem to experience a force pulling you back in the direction opposite to travel
or if you're on the inside of a spinning, cylindrical drum and you get stuck to the walls

These aren't fictitious you high schooler.

Both centrifugal and Coriolis force are proportional to [math]\omega^2 r[/math].
The angular velocity of the Earth around the Sun is one round per year, so you might see that it is quite negligible.
Plugging into Wolfram Alpha tells that the acceleration caused by Earth spinning around itself is 5.6 times larger than it spinning around the Sun.
The fictitious forces caused by this are measurable, especially Coriolis.

> When a car accelerates, a passenger feels like they're being pushed back into the seat. In an inertial frame of reference attached to the road, there is no physical force moving the rider backward. However, in the rider's non-inertial reference frame attached to the accelerating car, there is a backward fictitious force.

Looks like you're the one who should have paid more attention in highschool , kid
