Newton's Law of Motion Explain, First, Second and Third Law, Example and Formula

Law of motion.

The law of motion states that an object in motion will stay in motion, and an object at rest will stay at rest, unless an external force acts upon it. The law of motion is also known as Newton's First Law of Motion.

Newton's law of motion explain.

Newton's three laws of motion state that every object in a state of uniform motion will remain in that state of motion unless an external force acts on it; that the relationship between an object's mass m, its acceleration a, and the applied force F is F = ma; and that for every action there is an equal and opposite reaction. In other words, the acceleration of an object is directly proportional to the net force applied to it, and inversely proportional to its mass. For a constant mass, the acceleration of an object is directly proportional to the net force applied to it. The net force applied is equal to the sum of all the individual forces acting on the object.

Newton's laws of motion are a set of three fundamental laws of physics that describe the relationship between a body and the forces acting upon it. These laws, which were first formulated by English physicist and mathematician Sir Isaac Newton in the late 17th century, are as follows:

1. The first law, also known as the law of inertia, states that an object will remain at rest or in motion at a constant velocity unless acted upon by an external force. This means that an object will continue to stay still or move in a straight line at a constant speed unless something else pushes or pulls on it.
2. The second law states that the rate of change of momentum of a body is directly proportional to the force applied, and occurs in the direction in which the force is applied. Mathematically, this can be expressed as F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration experienced by the object.
3. The third law states that for every action, there is an equal and opposite reaction. This means that if one object exerts a force on another object, the second object will exert an equal and opposite force back on the first object.

These laws are fundamental to understanding how objects behave and interact with each other in the physical world, and form the basis of classical mechanics, which is the study of how objects move and interact with each other.

Newton's law of motion example

Here are a few examples of how Newton's laws of motion can be observed in everyday life:

1. The first law: If you are sitting in a stationary car and someone pushes you from behind, you will remain at rest unless you are pushed with enough force to overcome your inertia and start moving. Similarly, if you are riding a bike and stop pedaling, the bike will continue to move at a constant velocity until something (such as friction or wind resistance) slows it down.

2. The second law: If you are riding a bike and want to speed up, you will have to pedal harder to apply more force to the bike. The harder you pedal, the greater the acceleration you will experience. The same is true if you are driving a car and want to accelerate - you will have to press the gas pedal harder to apply more force to the car's engine.

3. The third law: If you are playing catch with a friend, you will have to throw the ball with enough force to overcome the force of gravity pulling it downward. When your friend catches the ball, their hand will push back against the ball with an equal and opposite force, causing the ball to stop moving. Similarly, when you walk or run, you push against the ground with your feet, and the ground pushes back against you with an equal and opposite force, propelling you forward.

Newton's law of motion formula.

Here are the mathematical formulas for each of Newton's laws of motion:

1. The first law: An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force. This can be expressed as:

F = 0

where F is the net force acting on the object (the sum of all the forces acting on the object). If F is zero, the object will remain at rest or continue moving at a constant velocity.


2. The second law: The rate of change of momentum of a body is directly proportional to the force applied, and occurs in the direction in which the force is applied. This can be expressed as:

F = ma

where F is the force applied, m is the mass of the object, and a is the acceleration experienced by the object.

3. The third law: For every action, there is an equal and opposite reaction. This can be expressed as:

F1 = -F2

where F1 is the force exerted by the first object on the second object, and F2 is the force exerted by the second object on the first object. The forces are equal in magnitude but opposite in direction.

The Continental Drift Theory is the idea that the Earth's continents have moved over geological time relative to each other, thus appearing to have "drifted" across the ocean bed.

Wegener proposed that the continents were once joined together in a single landmass called Pangaea, which began to break apart and drift away from each other about 200 million years ago.
