Physics Laws of Motion and Theory of Relativity Quiz

Science

Science is the systematic pursuit of knowledge through observation, analysis, and experimentation. It encompasses various disciplines, including biology, chemistry, physics, astronomy, and mathematics. Each discipline within science requires its own unique set of methods and techniques to study phenomena in the natural world.

Physics

Physics is the branch of science concerned with matter, energy, and their interactions. It involves studying the fundamental laws of nature, such as those described by Isaac Newton's laws of motion and Albert Einstein's theory of relativity. These principles help us understand the behavior of physical objects from everyday life, like cars and balls, to cosmic phenomena, like black holes and galaxies.

Laws of Motion

Isaac Newton formulated three laws of motion, which describe the relationship between forces and motion. They are:

1. Every body persists in its state of being at rest or uniform motion in a straight line unless acted upon by a net external force.
2. The acceleration of any mass is directly proportional to the net force acting upon it and inversely proportional to the mass.
3. For every action, there is equal and opposite reaction.

Newton's laws laid the foundation for classical mechanics, still widely used today.

Theory of Relativity

Albert Einstein's theory of relativity explains the relationship between space and time, leading to the famous equation E=mc². This work revolutionized our understanding of gravity, space, and the universe.

Einstein proposed two theories under the broader concept of relativity, general relativity, which describes gravity, and special relativity, which deals with the speed of light. Both theories challenge traditional views of the physical world and have been confirmed by numerous experiments.
