GCSE PE - APPLICATIONS OF FORCE (FORCE DIAGRAMS)

 Resistance ;

resistance here causing the runner to accelerate in this example the horizontal arrow should be the same size as muscular force and air resistance must be balanced if the constant pace is to be maintained well done you've just covered everything you need to know on topic 5.2 make sure you're comfortable with everything included in the knowledge checklist and come back next time for the final topic in chapter 5 believers as always I hope you found this lesson.

Gravity;

Gravity will pull the ball downwards towards the pitch the free-kick taker, therefore, needs to judge the correct height and pace so that the ball clears the wall and drops in time to hit the target the shape and surface area of a projectile will influence the amount of air resistance it encounters because of this the air resistance acting on a football is greater than that acting on a golf ball and has a significant impact on the distance and accuracy that can be achieved from a goal kick the force applied as an object .

Released;

Released is determined by muscular force and will affect the distance of the lofted pass too little force and the pass will be intercepted while too much force could cause the ball to overrun now it's your chance to put what you've learned to the test pause the video now to draw two stick figures and add arrows to illustrate the forces acting while accelerating and moving at a constant pace make sure you include force arrows for all four forces the vertical arrows should be the same size and in opposite directions, as gravity is balanced by an equal and opposite ground reaction force muscular force is greater than air.
