In all of the videos a motion is being done.

Once their motion has started, they continue to move forever. Besides this, I think that their motion includes circular motion. Earth rotates around itself, metronome's arm draws an arc in it's motion and newton's crandle consists of five spheres. Their motions are sort of a circular motion, and I think their motions are related with trigonometric functions.

In order to stop them, an external force is required.]]> 2018-03-12 17:28:51 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241013110 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241046919 All three videos contain a continous motion. The things represented in the video use different kinds of force to keep its constant state; the World shown has a gravitional force, the metronome has a weight and newton's cradle uses physical impulse. The motion will continue until an external force is acted upon them.]]> 2018-03-12 18:18:47 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241046919 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241049793 In all of these videos there is a repeated motion. All of the objects take a route similiar to an arc of a circle.]]> 2018-03-12 18:22:59 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241049793 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241073421 In all of the videos below there is a continious motion that is done by an object. If there is no another force applied to them they will continue to do their motions forever.

The friction on the objects are negligible so that objects will continue to its state until another force acts on them and changes the energy of the system.]]> 2018-03-12 19:07:56 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241077151 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241106107 I think that the similarity of these three videos is that the motion observed in all of them are continuous. Moreover, all of them were a bit mysterious because they make us to wonder what is the "mystical" force which allows them to continue to their motion. The reason is that energy is conserved where friction is minimal.]]> 2018-03-12 20:15:11 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241106107 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241111160 All the videos show a continous motion happening and some of them can change the speed the motion is being done so maybe these motions could be represented by a function.

I think that the animation of rotation of Earth and Newton's Cradle have a relation with trigonametric functions because we use unit circle in trigonametry and both of the examples include spheres that are moving. It represents the radian. The metronome also has a relation with trigonametry. I think that it represnets the angle, degree.]]> 2018-03-12 20:55:41 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241119545 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241124361 The similarities between these videos is that all of the videos are showing a continuous motion. There are physical acts on each of the motion which are called forces and the similarity in the videos is that in every video there is a negligable friction force and therefore a little loss of (kinetic or potential) energy, and that's why they are continuing their motion, small energy losses during their motion. ]]> 2018-03-12 21:08:37 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241124361 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241138164 In all those videos, there where moving objects. They were continuing to move untill an externel force starts to act on them. The objects were moving because there were just a little amount of energy loss. This can be explained by Newton’s Laws of Motion]]> 2018-03-12 22:03:25 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241138164 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241145437 The similarities in the videos were that all of them show motion which I think could be represented with trigonometry.]]> 2018-03-12 22:42:41 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241145437 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241372436 These 3 videos have objects which are in continious motion if external forces are zero so they all have periods. Also, they are all connected to a center and moves around this center. All of these videos have circular motion in them. They all have angular velocities.]]> 2018-03-13 13:51:17 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241372436 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241384382 2018-03-13 14:07:33 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241384382 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241486220 In all the videos, the objects moves continious until an external force aplied them.]]> 2018-03-13 16:31:16 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241486220 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241496794 In all of these videos, the objects are performing a continuous motion. ]]> 2018-03-13 16:47:12 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241496794 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241580767 I think that in these videos there are three similarities. The first one is that the objects in all of the videos have a constant frequency. That's why they always repeat the same type of motion in one second. This is because they have have a constant speed. The second similarity is that in all videos, there is an external force that acting on the objects. That's why while the speed of the object remains the same, its velocity changes due to change in direction. For instance, the earth would go somewhere else in the space, if there wasn't the gravitational attraction force of the sun. The balls would have completed their revolution if there was no gravitational force, and the stick of the metronome would have go straight, if there wasn't an opposite force. The last similarity is that they all are likely to make circular motion, if there was no external force acting upon them. ]]> 2018-03-13 18:55:53 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241580767 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241597110 There are similarities in these videos. One of them is that objects are in continuous and circular motion. They are all moving respect to the center which causes a circular motion. They all have constant velocity if there aren't any external forces. ]]> 2018-03-13 19:29:20 UTC https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241597110 https://padlet.com/busra_sasmaz55/xbdki2nrjzji/wish/241609379 In 3 of the videos, there were real-life examples such as; Newton's cradle, rotation of Earth and the metronome. So, in all of them, the similarity was their main aim which is the circular motion. During their motion process, it is obvious that they will continue to move forever.
