Presentation transcript:

The physics of falling In this section you will be introduced to the idea of terminal velocity know what factors can affect the size of the terminal velocity consider the forces that affect a falling object

We will look at how forces affect the motion of the falling object.

velocity Terminal velocity ? time

velocity Weight What do we know about the weight? time

velocity Weight What do we know about the weight? It stays the same time

velocity What about the drag (air resistance)? No movement no drag! As the object starts falling the drag force is smaller than the weight so the object accelerates Weight Eventually the drag force becomes equal to the weight so the object stops accelerating (reaches it’s terminal velocity) time

velocity What about the drag (air resistance)? No movement drag! As the object starts falling the drag force is than the weight so the object Weight Eventually the drag force becomes to the weight so the object stops accelerating (reaches it’s ) time

increasing the mass of the object will the terminal velocity Notes Terminal velocity velocity all falling objects reach a speed this happens when the weight and the drag are time increasing the mass of the object will the terminal velocity decreasing the surface area will

increasing the mass of the object will increase the terminal velocity Answers Terminal velocity velocity all falling objects reach a top speed this happens when the weight and the drag are equal time increasing the mass of the object will increase the terminal velocity decreasing the surface area will
