The car comes to a sharp turn in the road

The car has to stop quickly

The car is stopped and has to start moving

Note: The coefficient of friction is not an actual force acting on the car unless there is an outside force attempting to break the car out of equilibrium. It is then that the friction acting on the car while at rest will come into play.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
