ard. The car, since it is slowing down, is an accelerating, or non-inertial, frame of reference, and the law of inertia no longer holds if we use this non-inertial frame to judge your motion.

If all of this is viewed relative to the ground, it becomes clear that no force is pushing you forward when the brakes are applied. The ground is stationary and, therefore, is an inertial frame. Relative to the ground, when the brakes are applied, you continue with your forward motion, just like you should according to Newton's first law of motion. The situation is this: the car is stopping, you are not; so, you head out toward the dashboard. From your point of view in the car it seems like you have spontaneously been pushed forward. Actually, there is no force acting on you. The imagined force toward the front of the car is a fictitious force.

A similar fictitious force can be noticed by a person in a car when it speeds up. Let us say that you are in a car at a stop light. The car is standing still. The light turns green, and the car accelerates forward. While undergoing this acceleration, the car is a non-inertial frame of reference. If the acceleration is large enough, you will feel yourself "pushed" into the seat. Actually, no force is pushing on you. Again, as viewed from the inertial frame of the ground, you are just maintaining your velocity, as you should according to Newton's first law of motion. You were still when the light was red, and you are attempting to remain still when the light turns green. However, the car started to move when the light turned green. The car actually comes up from behind you, and, using the seat, the car pushes you forward. As the seat comes forward and pushes on you, the back seat cushion compresses a bit. You may interpret this feeling as your body being pushed backward into the seat. Really, you are attempting to maintain your velocity of zero, and the seat is coming up from behind to push on you. There is no backward force. The imagined force is a fictitious force. Fictitious forces arise in non-inertial, or accelerating, frames of reference.

There are several ways to describe a non-inertial frame. Here are a few descriptions:

A non-inertial frame of reference is a frame of reference with a changing velocity. The velocity of a frame will change if the frame speeds up, or slows down, or travels in a curved path.
A non-inertial frame of reference is an accelerating frame of reference.
A non-inertial frame of reference is a frame of reference in which the law of inertia does not hold.
A non-inertial frame of reference is a frame of reference in which Newton's laws of motion do not hold.
In a non-inertial frame of reference fictitious forces arise.
What follows here are two demonstrations that show non-inertial frames of reference. The first one is an animation of a non-inertial frame which acts like an elevator. The other shows an animation of a rotating frame of reference. Rotating frames of reference are non-inertial frames since they are following curved paths. Remember that a change in direction, which would occur along a curved path, constitutes a change in velocity, and, therefore, constitutes an acceleration. If the frame accelerates, it is a non-inertial frame.
