Some athletic shoes have inflatable air pockets inside them. these air pockets act like springs that become stiffer as you pump up the air pressure. high pressure also makes you bounce back up off the floor sooner. why does high pressure shorten the bounce time?

Stiffer air pockets mean less distortion. More distortion takes more time

Explanation:

Distortion is the alteration of the characteristics of something. In this case, the characteristics would be the shape of the air pocket that is distorted when the shoe hits the ground with your weight on top of it.

If the air is at a higher pressure and it becomes stiffer, it would allow the air pocket to distort less on the impact. Less distortion would take less time to take place than a higher level of distortion.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
