We can determine the speed by using the formula acceleration = net force / mass of object ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785371743 2023-11-10 21:43:37 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785371743 In a push/pull interaction the objects will exert equal force in strength on each other in the opposite direction. In this example, when the car pushes the wall with a set amount of force, the wall reacts back by pushing the car with a force equal to the strength of the force the car applies. ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785374680 2023-11-10 21:51:17 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785374680 Force Diagram: uses arrows to represent the direction the force acts on the object in a certain time frame. The length of the arrows gives a relative depiction of the strength of the force and will typically be denoted in the unit Newtons (N) (the longer the stronger, the shorter the weaker) ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785398348

In this example (Rocket 100N + Engine 100N - Drag 50N = Net Force of 150N forward) ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785401474 2023-11-10 23:18:58 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785401474 Friction acts on an object "rubbing" against bumps in the surface in the opposite direction of the object's motion; friction is equal to the forward force(s) and increases as forward forces become stronger to a certain point; static friction is stronger than moving friction ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785404756 2023-11-10 23:29:30 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785404756 Backward Forces ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785404805 2023-11-10 23:29:39 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785404805 Examples of forces acting in the same direction of the object's motion and opposing the object's motion ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785405909 2023-11-10 23:33:54 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785405909 Sum of net forces ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785406803 2023-11-10 23:36:36 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785406803 ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785407191 2023-11-10 23:37:47 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785407191 Sideways forces: (forces that don't directly act in or against the object's motion) changes the direction of the object ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785409772 2023-11-10 23:47:13 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785409772 When forces continuously act on an object without directly opposing or in the same direction to the object in motion, the object will continue to rotate around the center if there is a common center ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785411451 2023-11-10 23:52:47 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785411451 unbalanced backward forces ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413252 2023-11-10 23:58:17 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413252 object will begin to slow down because the net force opposes the motion of the object ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413506 2023-11-10 23:59:00 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413506 object must come to a stop before changing directions; the object will eventually slow down to a stop then starts accelerating in the direction of the net force ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413724 2023-11-10 23:59:43 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413724 object continues to speed up in the direction of the net force ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413841 2023-11-11 00:00:07 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785413841 Sum of backward forces opposing motion ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785414130 2023-11-11 00:01:13 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785414130 When balance forces act on a object at rest, it remains at rest ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785415830 2023-11-11 00:06:47 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785415830 when balance forces act on a moving object, it continues to move at constant speed ehuynh71 https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785416625 2023-11-11 00:09:16 UTC https://padlet.com/ehuynh71/fbimlh91ucc1ztha/wish/2785416625
