Newton’s first law of motion is also known as?

• The 3 laws of Newton help us understand how objects behave when moving and when forces act upon them when they are standing still.
• The first law of newton implies that things cannot stop, start or change direction all by themselves. The things require some outside force.
• This property to resist changes of massive bodies in their state of motion is called inertia.
• The Second Law of newton states that the force acting on the body is equal to the product of its acceleration and mass.
• The Third Law of Newton states that for every action there is an opposite and equal reaction.

Additional information

• The Constancy Principle is a key concept in the theory of Special Relativity, formulated by Albert Einstein in 1905. It is crucial for understanding the behaviour of light and time in different reference frames, and it has profound implications in modern physics
• The Causality Principle asserts that every effect or outcome is the result of a specific cause, and this cause must precede the effect in time. It establishes a cause-and-effect relationship, which is central to understanding events, phenomena, and their interconnections
• The Principle of Relativity is a fundamental concept in physics, introduced by Albert Einstein which asserts that the laws of physics are the same for all observers in all inertial frames of reference, regardless of their state of motion. This means that no inertial frame is "special" or "preferred" over another, and the laws of physics must hold true in all such frames.
