Physics lab - Essay Example In fact, we create cars and vehicles with built-in breaks for us to be able to control their acceleration or speed and direction from time to time. We wear our seatbelts because of the danger associated with riding in a car vehicle in a speed. We also create objects with a design of making it easy for us to employ unbalanced force to transfer them from a place to another for instance and in order to break the law stating that they have the tendency to remain at rest once they do. The unbalanced force we might exert could be measured. A very important idea is the creation of meter for acceleration or speed in vehicles. Measuring the speed of an object in motion is important because in the case of automobiles this could at least ensure our safety on the road at a greater odds. On the other hand, ââ¬Å"when a force is applied to an object, the change of motion in the object is proportional to the force applied to the objectâ⬠(Grimshaw, 2007, p.74). This is Newtonââ¬â¢s powerful second law of motion. In a simple understanding, we can easily state this law in a manner that we are conscious of the fact that heavier objects require more force to move them. At this point, it is very important to calculate the specific amount of force usually is needed to be employed in order to move an object to a certain direction or distance. Based on this concept, Newton therefore was able to calculate force as the product of the objectââ¬â¢s mass and acceleration. This exactly applies and validates the stated given idea linked up with his second law of motion. Another learning from Newtonââ¬â¢s concepts and ideas include the relationship existing between static friction and gravity. From the class discussion, I learned that provided an object is set undisturbed on a surface for instance, the only force that acts on it is a gravity. Static friction is therefore developed in this case because the object
