If you had to name one fascinating subject that explains how the world around us works, that would be physics. Although the subject is an enticing culmination of logical explanations for the cosmic and physical universe around us, students often find it daunting to understand physics. There are many misconceptions surrounding the subject that prevent learners from comprehending the beauty of physics. With a physics tutor in Singapore, students can learn intricate subjects and debunk some myths surrounding the subject. To simplify things for you, here is a simplified version of some difficult concepts and their explanations from the experts of JC Physics tuition.
Objects at rest stay at rest, and objects in motion stay in motion
One of the most common misconceptions in physics is the idea that objects at rest will always stay at rest, and objects in motion will always stay in motion. This is not true, as many forces can cause objects to change their state of motion. For example, friction can cause an object to come to a stop, and an external force can cause an object to start moving.
Gravity is a force that pulls objects downwards
Another common misconception is the idea that gravity is a force that pulls objects downwards. While it is true that gravity causes objects to fall towards the ground, it is inaccurate to say that it only pulls things downwards. Gravity is a force that attracts everything towards each other, and the strength of this force depends on the masses of the objects and the distance between them. This is why planets orbit around stars, and moons orbit around planets.
Light travels in a straight line
Many people believe that light always travels in a straight line. While this is true in a vacuum, it is not always the case in other mediums. When light passes through a medium like water or glass, it can be bent or refracted, which is why all objects appear distorted when viewed through a glass of water or a lens.
Heat is a form of energy
Another common misconception is the idea that heat is a form of energy. While heat is often associated with energy, it is a transfer of energy from one object to another. Heat is the transfer of thermal energy from a hot object to a cold object. A common example given by the tutors in IP physics tuition for this phenomenon is the cooling down of coffee over time as it transfers its thermal energy to the surrounding air.
Mass and weight are not the same
Many people use the terms "mass" and "weight" interchangeably, but they are two different things. Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. This means that an object will have the same mass regardless of its location in the universe, but its weight will vary depending on the strength of gravity.
Conclusion
By debunking these misconceptions and clarifying these concepts, A-level physics tuition in Singapore can help students gain a deeper understanding and appreciation of the beauty of physics. With the best physics tuition, students can deeply understand the subject matter with the context and apply theoretical knowledge in the pragmatic universe effortlessly. Students with O-level physics tuition can also do better in their academia and take more interest in the subject. Professional tutors can also help them to cope with exam stress as they aid students to revise the subject matter more vividly.
