Have you even wondered why you have to sit your way through a science lecture in a classroom if every phenomenon stated in the book is happening outside? As we complete our high school with good grades, we're likely to be educated at the laws and mathematics of physics. However, the practical knowledge that we achieve is negligible when compared to the theory aspect of it.
Physics apply in daily life. So far, you must have learned about the movement of the object under an applied force, which lies under the realm of kinematics. Here are a few experiences from our day-to-day life that employ the principles of physics.
We are very much familiar with the motion of the body along a straight path. We do it every day. There are a few variables such as friction, velocity, acceleration, and displacement, etc., which we consider and maintain as we put ourselves in motion.
If you have studied it well, then it'll help you calculate the distance, time and direction, and let you read a map correctly.
As we put an object on the floor and start revolving around it, keeping the distance constant, we employ our body to follow motion along a circular path. There are two types of forces centrifugal and centripetal, which hold a body stable on its circular path. If any of the two forces exceed another, the body will lose its control. You can also read about the different variables like acceleration, velocity, and friction under circular path motion, as the principles different from straight line motion.
A body is subjected to act as a projectile when it's thrown freely in the air and gravity is the only phenomenon accelerating it. The acceleration acts in vertically downward direction while the horizontal velocity remains constant. By the application of the formulas of projectile motion, you can figure out the distance a stone will cover if you throw it with a certain amount of force at a specific angle in the air. Snipers also use the wind effect to calculate the deflection using the laws of projectile motion.
When two bodies, under perfect conditions, collide with each other, the total momentum of both the bodies, before and after the collision remains intact. However, when we take environment under consideration, there are a lot of variables that affect the seriousness of a crash. When Newton explained the phenomenon, he assumed that none of the bodies had lost their masses. Though when a collision actually happens, there's a significant loss of mass which also results in imperfect outcomes.
Under the three theories that Newton explained, we assume that the object is being pushed, pulled, and thrown across a frictionless plane. However, when friction comes into the picture, it comes with different values for different materials. The frictional constant ‘k' represents the endurance that a surface offers against any motion, and it's different for wood, marble, concrete, etc.
If you try and pay attention to the practical aspect of physics that your professors teach you in a lecture hall, you'll find that it is quite an interesting subject. Later, when you start learning the laws of light and sound waves, put those into their practical usage as well. There are a broad range of fields that physics can get you in.
