Slip (aerodynamics)

When you ride a bike or a car or anything that moves, the air around you also moves. This moving air creates a force that pushes against you, slowing you down or making it harder for you to go faster. This force is called drag.

Now, imagine you are riding your bike really fast and suddenly you hit a patch of gravel or a sharp turn. Your bike starts to wobble and you feel like you might fall off. This is because your bike is experiencing a slip.

Slip is when the direction you are moving in is different from the direction your wheels or other parts are facing. So, if your bike or car is pointed straight, but you are turning or sliding, you are in a slip.

When you are in a slip, the air around you moves in a different way than it would if you were driving straight. This can make the drag you experience stronger or weaker depending on the situation. For example, if you are going through a tight turn, being in a slip can actually help you turn faster because it reduces the drag.

However, slips can also be dangerous if you are not careful. If you are going too fast and you start to slip, you could lose control and crash. That's why it's important to always pay attention to your speed and driving conditions.
