Theories are modified over time due to new evidence or discoveries that may contradict or refine previous understanding. As more data is collected or technology advances, existing theories may be adjusted to better explain observed phenomena. This is a natural part of scientific progress, as theories evolve to accommodate better or more comprehensive explanations of … Read more
Scientific Method: The scientific method is a systematic approach to gaining knowledge through observation, experimentation, and analysis. It aims to answer questions about the natural world in an objective and repeatable way. Key Steps: Observation: Identify and observe a phenomenon. Question: Formulate a research question based on the observation. Hypothesis: Develop a testable explanation or … Read more
The terms hypothesis, theory, and law are fundamental concepts in the scientific method, but they differ in their roles, definitions, and the level of evidence supporting them. Here’s an explanation of each term along with examples: 1. Hypothesis Definition: A hypothesis is a proposed explanation or prediction based on limited evidence or observations. It is … Read more
The terms science, technology, and engineering are closely related but have distinct meanings and roles. Here’s a differentiation of each term along with suitable examples: 1. Science Definition: Science is the systematic study of the natural world through observation, experimentation, and analysis. It seeks to understand the fundamental principles and laws that govern the universe. … Read more
Physics plays a fundamental role in many other scientific disciplines, providing essential frameworks and tools that help to explain and explore phenomena across various fields. Here’s a brief overview of its importance in other disciplines: 1. Chemistry Atomic and Molecular Structure: Physics explains the behavior of atoms and molecules, which is crucial for understanding chemical … Read more
Physics plays a crucial role in our daily lives in ways that we may not always consciously recognize. From the technology we use to the natural processes that govern our world, physics impacts almost every aspect of our existence. Here’s a discussion on the importance of physics in everyday life: 1. Technology and Innovation Physics … Read more
Classical physics does not handle phenomena that occur at very small scales or high energies. Specifically, the areas classical physics does not address include: Subatomic Particles: Classical physics cannot explain the behavior of particles like electrons, protons, and photons, which are governed by quantum mechanics. 9: Classical physics fails to explain phenomena like wave-particle duality, … Read more
The validity of a theory is determined by: Empirical Evidence: It must be supported by experimental data. Testability & Falsifiability: Predictions should be testable and capable of being proven wrong. Consistency: It must be logically consistent and align with existing theories. Simplicity: The theory should explain phenomena with the fewest assumptions. Predictive Power: It should … Read more
Aspect Classical Mechanics Quantum Mechanics Scale of Application Describes the motion of macroscopic objects (e.g., cars, planets). Describes the behavior of microscopic particles (e.g., atoms, electrons). Key Principles Based on deterministic laws (e.g., Newton’s laws of motion). Based on probabilistic principles (e.g., wave-particle duality). Certainty of Behavior Predicts the exact position and velocity of an … Read more
A hypothesis is a proposed explanation or prediction based on limited evidence, which can be tested through experimentation or observation. In scientific research, a hypothesis is usually formulated before conducting an experiment and serves as the basis for testing whether certain factors or variables influence an outcome. There are two main types of hypotheses: Null … Read more
