Important for calculating air resistance in respect to airplanes and fuel.

The drag of the air makes it hard for the plane to move quickly.

Important for calculating the distance of a projectile by using its speed and duration in the air.

The path of a projectile is its trajectory.

Why is this important?

Drag can be a useful force for slowing things down.  This is good for flight because it keeps planes from taking a nose diving into the ground.

It is important because it is the peak of an equation.

The living room extends right up to the apex of the roof. 

  Acceleration- Increase in the rate of speed of something

It is important because it determines the rate an object uses its velocity.

The ball moves under constant acceleration of gravity during its flight to the ground.

It is important because inclined surfaces are used for

many structures such as rooftops and aiding in raising

and lowering objects.

There are few chest exercises with muscle recruitment

comparable to that of an incline bench press.
