Answer:
FIRST LAW
Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia. The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes. Before Galileo it had been thought that all horizontal motion required a direct cause, but Galileo deduced from his experiments that a body in motion would remain in motion unless a force (such as friction) caused it to come to rest.
Scoend law
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity. Momentum, like velocity, is a vector quantity, having both magnitude and direction. A force applied to a body can change the magnitude of the momentum, or its direction, or both. Newton’s second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation. Conversely, if a body is not accelerated, there is no net force acting on it.
third law
Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. This law is important in analyzing problems of static equilibrium, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion. The forces it describes are real ones, not mere bookkeeping devices. For example, a book resting on a table applies a downward force equal to its weight on the table. According to the third law, the table applies an equal and opposite force to the book. This force occurs because the weight of the book causes the table to deform slightly so that it pushes back on the book like a coiled spring.
Newton's First Law :
Newton's first law states that every object try to remain at rest or in uniform motion in a straight line unless an external force is applied to it .
Examples of Newton's First law :
- A ball rolling down a hill will continue to roll unless friction or another force stops it.
- Shaking a bottle of ketchup. When bringing the bottom down, the suddenly stopping it, inertia is what causes the ketchup to come out of the bottle.

Newton's Second Law :
Newton's second law states that the acceleration of an object is dependent upon two variables - The net force acting upon the object and the mass of the object. { F = ma }
Examples of Newton's Second law :
- It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.
- Some elevators have a sign saying that only a certain amount of people can use it at a time, because they have a maximum acceleration and force with which they move, which means they can only sustain a maximum mass, which is then translated into a certain number of people.

Newton's Third Law :
For every action, there is an equal and opposite Reaction .
Example of Newton's Third law :
- Slapping: When you slap someone your hand feel pain as well as the check of the victim. The pain in check due to action and in palm due to reaction force.
- Rocket: Then the rocket tool flight it exhaust the gas from it's back. The reaction force push rocket forward.
