Momentum plays a vey big part in cheerleading. Without momentum, while we stunt the bases would have a hard time lifting the flyer in the air. When the flyer jumps into the bases hands it creates a momentum to push the flyer into the stunt to the left known as a "half."
As shown to the left, the cheerleader is taking a leap into her running tumbling. She needs to run before she starts to do flips and turns so she can get the momentum she needs to complete her skills. In order to get momentum she creates a distance between how long she needs to run and the time she needs to start tumbling.
This cheerleaders is about to form a task known as the "toe touch." This is when you jump for a crunch as your raise and spread your legs into a T like shape. Your put a force to your body as you jump upward and extend your legs. A toe touch relates to impulse.
Impulse also relates to squad running tumbling. This is when two or more people match there momentums and steps to time there tumbling together, there fore they will be doing the same things at the same time. They must apply the same or very similar amount of force for a set time so one does not fall behind or in front of the others. In this case impulse, timing and momentum are key.
The stunt being performed here is called a basket. The bases toss the flyer up into the ear using momentum. The momentum takes the flyer into the air so she is able to perform enhancive tricks. With momentum going upwards she goes further up.
In conclusion, momentum and impulse is used every single day in cheerleading. WE use momentum for throwing stunts, running and standing tumbling, and so much more. We use impulse to match our momentum with timing.
