The passengers in a roller coaster car feel 50% heavier than their true weight as the car goes through a dip with a 30.0 radius of curvature.
Fictitious forces, also known as pseudo forces or inertial forces, are apparent forces that appear to act on objects in non-inertial reference frames. These forces are not real forces, but rather the result of an object's acceleration relative to a non-inertial reference frame.
The main difference between fictitious forces and real forces is that fictitious forces do not arise from physical interactions between objects, but rather from the choice of reference frame. Real forces, on the other hand, are the result of interactions between objects, such as gravitational, electromagnetic, or contact forces.
Fictitious forces do not actually affect an object's motion, as they are not real forces. However, they do appear to act on an object in a non-inertial reference frame due to the frame's acceleration. In an inertial reference frame, an object will not experience fictitious forces.
Apparent weight is the weight that an object appears to have when it is in a non-inertial reference frame. This is due to the fictitious forces that arise from the frame's acceleration. For example, on a spinning amusement park ride, a person may feel heavier due to the centrifugal force acting on them, even though their actual weight has not changed.
In order to accurately account for fictitious forces, it is important to choose the appropriate reference frame for the situation. In some cases, it may be necessary to switch to an inertial reference frame in order to eliminate fictitious forces from the calculations. In experiments, it is important to carefully consider the reference frame and any potential fictitious forces that may affect the results.
