Answer:
Applications of Physics in Everyday Life
Playing hockey, driving a car, and even simply taking a walk are all everyday examples of Newton's laws of motion. Compiled in 1687 by English mathematician Isaac Newton, the three main laws describe forces and motion for objects on Earth and throughout the universe

Answer:
Isaac Newton was one of the most important figures in the history of science. While we’ve written about him in the past, many of his laws of motion are still misunderstood. So we’ve put together this blog post to summarise each of his 3 laws of motion with the relevant equations and a real-life example:
First Law
Also known as the law of inertia; Newton’s first law of motion states that: “An object in motion will remain in motion and an object at rest will remain at rest unless acted upon by a force”.
The second and third laws follow-on from this and use this first law to establish a frame of reference.
Second Law
The second law of motion states that: “Net force is equal to mass times acceleration”. This can be explained mathematically using the equation:
F=ma
Where F is the net force placed on the object, m is the object’s mass and a, the acceleration.
Third Law
Newton’s third and probably most well-known law of motion states that: “For every action, there is an equal and opposite reaction”. Also known as the normal force, this law of motion is one of the easiest to observe but one of the hardest to understand intuitively.
Example:
i) A book on your table does not come towards you unless you put effort to take it
ii) The Earth and other planets will not revolve around the sun when there exists no gravitational field.
iii) A rocket or any other propelling object does not take off unless a force equal to its weight is applied on it.
