Applications of Newton’s laws of motion

Newton's laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries, and can be summarized as follows: 1- The first law states that an object continues in its state of rest or uniform motion in a straight line unless compelled by an external unbalanced force. Since law defines inertia, it is also known as the law of inertia. 2- The second law states that the rate of change of momentum of an object is proportional to the frce applied and moves in the direction of force. 3- The third law states that every action has an equal and opposite reaction and acts on different bodies. Applications of Newton’s laws of motion
Newton’s first law of motion 1- Seat bleats exert force on our body to make the forward motion slower. An opposite experience is encountered when we are standing in a bus or a train and the it moves suddenly. We tend to fall backwards. This because the sudden start of the bus brings motion to the bus as well as to our feet in contact. 2- When a motor car makes a sharp turn at a high speed, we tend to slip or thrown to one side.
Newton’s second law of motion
1-a cricket player pulls back his hands to catch a fast moving ball. In doing so, the fielder increases the time during which the high velocity of the ball decreases to zero and thus, the fielder does not get hurt. 2-in a high jump athlete events, the atheists are made to jump on a cushion bed or on a sand bed. Newton’s third law of motion 1- When a bullet is fired from a gun, the force sending the bullet forward is equal to the force the gun backwards. This is because every action has an equal and opposite reaction.

    Inertia is what keeps an object in its rest state or moving at constant velocity. In other words, it is the tendency for objects to resist a change in their motion. The only thing inertia depends on is the mass of the object, so heavier objects have more inertia and it is harder to change its motion. When you accelerate quickly, you get pushed back against the seat. Because of inertia, your body keeps traveling at the same velocity as before the acceleration. Inertia can also be experienced when the car turns sharply and you get pushed to the opposite side because the body wants to continue in a straight line. This tendency (for objects to be kept in its rest state or keep moving at its…

    First, Growing up Newton had a difficult life. He was born as a premature baby. He also had to grow up without his dad because his dad passed away three months before he was born. When Newton was three his mom left him to go live with her new husband, leaving him to live with his grandparents. Newton has many influences on today’s life. One of his many influences on us today is the Three Laws Of Motion. The idea of the Three Laws Of Motion states that anything at rest will stay at rest unless an outside force affects it.…

    Newton’s Third Law; the motion states that for every action there is a an equal and opposite reaction that acts with the same momentum and the opposite velocity. An example would be a suction cup and spring attached to it. Sticking the object to a window, having the spring be squeezed together. Eventually, depending on how powerful your suction cup is, the object would spring off…

    Newton’s first law was an object in motion will continue moving unless something stops it from moving. That law relates to my project by saying my contraption will stay in motion till it hit the ground. Newton’s second law was heavier the object the more force it takes to move and lighter objects require less force too move. The force in which the egg hits the ground will equal the mass of the egg. Newton’s third law is for every action of force there is an equal and opposite reaction of force. While moving downwards, the force of gravity is pulling the egg down. However, when the force is acting on the opposite direction too that’s due to air resistance.…

    These laws helped others create several inventions and expanded the world's view on mechanics. For example, many amusement park rides began from Newton's laws of motion, roller coasters and Ferris wheels. One law states that an object in motion will say in that motion, unless acted on by an external force. For example, a roller coaster is made with hills so that the motion of the roller coaster won't be stopped by friction till the ride is over. Another law states that an object's acceleration is determined on the amount of force and the mass of the object. For example, if a person kicked a brick wall, it wouldn't move, but if the person kicked a balloon, it would move. Another example of the law is inside an engine; when the gasoline explodes in the cylinder of an engine, the force of the explosion forces the piston to move, which projects the machine in a direction. The final law of motion states that every action has an equal and opposite reaction. For example, a bird flies because it's wings push the air down, forcing the bird up into the air. An example of an invention for this law is the invention of rockets. A rocket is projected forward by an engine, while pushing the flames and exhaust backwards. These laws also helped English inventors create new inventions: the first internal combustion engine, the first electrical generator, the linear motor, the hydraulic crane, the…

    Another observation that Newton had conducted was that the moon would move away from the earth in a straight line tangent to its orbit. He knew that there was a force that was preventing the moon from falling towards the earth. Newton had then concluded this invisible force to be called “gravity.” Newton had determined that gravitational forces exist between all objects. After all the observations he made, Newton developed what are now known as the three laws of motion. The first law covers the definition of inertia. Inertia focuses on how an object will remain in motion or at rest in a straight line unless forced to change by the addition of an external force. Objects in motion will stay in motion, and objects at rest will stay at rest. The only time that an object should move is if there were an outside force. Moving on to the second law, which explains how the acceleration of an object can change when an additional force is utilized. The second law directly states that the force needed to accelerate an object equals the mass of the object multiplied by its velocity.…
