Explanation:
Certainly! Here are simple explanations and examples of Newton's three laws of motion:
1. **Newton's First Law (Law of Inertia)**:
An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced external force.
**Example**: When you slide a book on a table, it eventually comes to a stop because of the force of friction, demonstrating the tendency of objects to resist changes in motion.
2. **Newton's Second Law (Law of Force and Acceleration)**:
The acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This law is often written as F = ma, where F is the force, m is the mass of the object, and a is its acceleration.
**Example**: If you push a small and large car with the same amount of force, the smaller car will accelerate more because it has less mass, according to Newton's second law.
3. **Newton's Third Law (Action-Reaction Law)**:
For every action, there is an equal and opposite reaction. When one object exerts a force on another, the second object exerts an equal force in the opposite direction.
**Example**: When you walk, your foot exerts a backward force on the ground (action), and the ground exerts an equal and opposite forward force on your foot (reaction), propelling you forward.

Answer:
Newton's first law of motion
every in animated object continuous to be in its state of rest or of uniform a accelerated motion and less and until it is acted upon by an external unbalanced force.
importance of Newton's first law of motion
first it shows and equivalence between state of rest and state of uniform motion along a straight line as both need a net unbalanced force to change the state both these are referred as the state of motion the distinction between state of rest and uniform motion lies in the choice of the frame of reference
Newton's second law of motion
rate of change of linear momentum of rigid body is directly proportional to the applied force and takes place in the direction of applied force.
importance of Newton second law of motion
it gives mathematical formulation for quantitative measure of force as rate of change of linear momentum Aristotle flancy is overcome by considering resultant unbalanced force.
Newton's third law of motion
to every action which is force there is an equal and opposite reaction which is also and force.
importance of Newton's third law of motion
it defines action and reaction as a pair of equal and opposite forces acting along the same line action and reaction forces are always on different objects.
