- Mass, force and weight (Mass versus weight)
- Momentum and conservation of energy
- Gravity, theories of gravity
- Energy, work, and their relationship

What are the two basic principle in physics?
The two basic principles in physics are the principles of motion and principles of electromagnetism The Newton’s principles of motion define a body ‘s relationship with the forces acting on it, and its motion in response to those forces
What is the first rule of physics?
The focus of Lesson 1 is Newton’s first law of motion – sometimes referred to as the law of inertia Newton’s first law of motion is often stated as An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
How many laws of physics are there?
Three Laws
Who invented physics?
Galileo
What is a principle in physics?
A principle is a rule or mechanism by which specific scientific phenomena work Principles can also describe specific values and concepts such as entropy or Archimedes principle, which relates buoyancy to the weight of displaced water
How do you explain physics?
Definition Physics is the study of energy and matter in space and time and how they are related to each other Physicists assume the existence of mass, length, time and electric current and then define (give the meaning of) all other physical quantities in terms of these basic units
What is a physics concept?
Physics concepts aren’t just for scientists—they’re important for anyone It the study of the physical world It covers a range of topics including matter (which is any substance that has mass), and the movement of that matter through space and time in the universe
Why do we study physics?
Physics helps you to understand the world around you, and satisfy your curiosity Studying physics develops your critical thinking and problem-solving skills Physicists are versatile, which opens a wide range of future careers
What is importance of physics?
Physics explains the fundamental laws of the universe and introduces important concepts that are essential for advanced study of chemistry, biology and all other branches of science Physics is essential for understanding chemistry Without physics students cannot understand major chemical principles, for example
Where is physics used?
Physics extends well into your everyday life, describing the motion, forces and energy of ordinary experience In actions such as walking, driving a car or using a phone, physics is at work For everyday living, all the technologies you might take for granted exploit the rules of physics
How is physics important in our daily life?
Physics, or the study of matter, energy, and the interactions between them, helps us to understand the laws and rules that govern the physical world Not every student will grow up and study physics on a deeper level, but everyone uses basic physics concepts to navigate everyday life
Is studying physics hard?
Physics can be a difficult subject to master, and the first year of an undergraduate course can be an especially steep learning curve
