This picture shows waves in a lake caused by vibrations. Wavelength, intensity, and frequency can all be seen.]]> 2021-08-16 19:03:48 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680909020 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680912273 Glasses use optics in real life. The picture shows glasses that are used to focus an image. The lenses bend light to focus them for the user.]]> 2021-08-16 19:06:47 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680912273 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680917254 A ratchet uses torque in real life. The picture shows a ratchet being used to tighten a bolt. The ratchet uses force to turn a bolt around its axis.]]> 2021-08-16 19:11:34 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680917254 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680927884 Bridges make use of tension in real life. The picture shows a bridge that uses cables to hold the tread up. The force pulling the cable is used as a normal force on the treads.]]> 2021-08-16 19:21:06 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680927884 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680932029 Driving is a real life example of friction. The picture shows a car accelerating. The force holding the tires to the ground make it so that the wheel needs to roll forward in order to spin.]]> 2021-08-16 19:25:00 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680932029 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680939201 Throwing a ball is an example of projectile motion. The picture shows someone throwing a ball through the air. It demonstrates how vertical and horizontal forces will propel an object.]]> 2021-08-16 19:31:50 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680939201 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680942906 A speaker produces sound. The picture shows a speaker being used to create sound. Waves of different intensity are created by the membrane, which then travel to one's ear.]]> 2021-08-16 19:34:55 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680942906 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680949444 A weed-whacker is an example of circular motion. The picture shows a weed-whacker spinning a string in order to cut grass. The motor spins the string in a circular motion, which causes the ends to speed up even faster.]]> 2021-08-16 19:40:51 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680949444 shoemcol000 https://padlet.com/shoemcol000/14895spake577phb/wish/1680954022 A pendulum is an example of simple harmonic motion. The picture shows a pendulum that swings with consistent timing. The pendulum conserves its energy and follows a consistent repeating past as forces shift.]]> 2021-08-16 19:45:17 UTC https://padlet.com/shoemcol000/14895spake577phb/wish/1680954022
