How does newtons second law of motion relate to life?

Newton's second law of motion (F=ma) highlights the relationship between the force acting on an object, its mass, and its acceleration. In daily life, this law can be observed when pushing a heavy object requiring more force to accelerate it compared to a lighter object. It also explains why larger vehicles require more force to accelerate than smaller ones.

What did Isaac Newton and Albert Einstein have in common?

Isaac Newton and Albert Einstein were both renowned physicists who made significant contributions to the field of science. They both formulated groundbreaking theories that revolutionized our understanding of the physical world: Newton with his laws of motion and universal gravitation, and Einstein with his theory of relativity. Both Newton and Einstein are considered among the greatest scientists in history.

How can you use newtons third law of motion to describe the forces represented by arrows?

Newton's third law states that for every action, there is an equal and opposite reaction. In the context of forces represented by arrows, if one arrow represents a force acting on an object, then there must be another arrow representing an equal and opposite force acting on a different object. These two forces are a pair of action-reaction forces as described by Newton's third law.

How does isaac newton's contribute to math compare to todays math?

Isaac Newton made significant contributions to mathematics, particularly in the development of calculus and the laws of motion. His work laid the foundation for many concepts and techniques used in mathematics today. While modern mathematics has expanded and evolved in many ways beyond Newton's time, his contributions continue to be fundamental and influential in the field.

Did isaac newton have a mustache?

Yes, Isaac Newton did have a mustache. There are portraits and descriptions of him with facial hair, including a mustache.

What do you call the tendency of matter to stay at rest if it is at rest or continue moving at a constant velocity if it is in motion?

That tendency is called inertia. According to Newton's first law of motion, an object will remain at rest or continue moving in a straight line at a constant speed unless acted upon by an external force.

Did Isaac Newton invent hopscotch?

No, Isaac Newton did not invent hopscotch. Hopscotch is believed to have originated in ancient times as a children's game played by hopping through a series of squares drawn on the ground.

What other scientific topics did sir isaac newton have ideas about?

In addition to his work in physics and mathematics, Sir Isaac Newton also made significant contributions to the fields of optics, astronomy, and alchemy. He developed the theory of colors, established the laws of motion and universal gravitation, and invented the reflecting telescope to observe celestial bodies. Newton also conducted research into the transmutation of metals and the nature of light.

What force is required to move an object when there is no friction?

That depends. If the object is free falling then Fg (force of gravity[9.81m/s^2 near earths surface]) would be a force acting upon the object as well as air resistance working in the other direction. If the object is on a frictionless surface, then Fn (normal force) Fg(gravitational force), and Fa(force applied to the object) would be the forces acting upon it. The equation for calculating net force is Fnet=ma m=mass in kg a=acceleration(m/s^2) Hope this helps!

What was Isacc Newton email address?

Newton died in 1727 and the internet wasn't invented until the 1980's. It would have been impossible for him to have had an email address.

What are 3 main achievements of Isaac newton?

  1. Formulated the laws of motion, laying the foundation for classical mechanics.
  2. Developed the theory of universal gravitation, explaining the motion of planets and objects on Earth.
  3. Made significant contributions to mathematics, including the development of calculus.

What are some good songs that relate to Isaac Newton?

Free Fallin' by Tom Petty and the Heartbreakers; because of his laws on gravity. Also, You Spin Me Round (Like a Record) by Dead Or Alive; because he found that the planets revolve the sun in an elipse, not a circle.

What is newton formula for acceleration?

The formula for acceleration is given by a = F/m, where a is the acceleration, F is the force applied, and m is the mass of the object. This formula is derived from Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Is newton cradle an example of newton's second or third law?

I believe it's Newtons second law because, the definition of Newtons second law is : An object acted by a force will accelerate in the direction of the force. When you push someone if you push hard enough their body will move in the direction they were pushed or forced to go or travel.

What was sir Isaac newtons role?

being an epic scientist

~

Sir Isaac Newton made plenty of scientific discoveries- tough the most famous is gravity, he also discovered the Three Universal Laws of Motion, which was then made into basic Physics by him. This helped prove Copernicus's theory of the planets orbiting the Sun. He also made the Binomial Theorem and was one of the two creators of calculus. Ultimately, his discoveries were predecessors to discoveries made by the other great scientists, such as Einstein.

When we hit a wall why don't we bounce back as Newtons third law states?

Newton's 3rd law doesn't state anything of the kind.

The reason we don't bounce back from a wall is because we're sort of inelastic. We do "bounce back" to a certain extent, but not the same way a rubber ball does.

What is an object's resistance in speed or direction until an outside force is acted upon it?

Inertia is an object's resistance to a change in speed or direction until an external force is applied to it.

What will happen to a object at rest if no unbalanced force acts on it?

If no unbalanced force acts on an object at rest, it will remain at rest according to Newton's first law of motion.

What factor did Newton take into account that Kepler missed in his laws of planetary motion?

Newton took into account the force of gravity, which he showed was responsible for keeping the planets in orbit around the sun. Kepler's laws described the motion of planets but did not provide an explanation for what caused this motion.

What did Isacc Newton go to school for?

As a young man in his teens, Sir Isaac Newton attended The King's School in Grantham, England. In 1661, Newton enter Trinity College in Cambridge, where he completed is education in 1668 with his Master's Degree.

What is the newtons second law of acceleration in the braking distance of vechicles?

install some (arbitrary) numbers:

mass (m) = 1 000 kg

( braking ) force (f) = -10 000 newtons (negative because the force is opposing direction of motion)

braking from 70 metres / sec to rest, so:

u = 70 metres / sec

v = 0 metres / sec

.

first find acceleration (a):

newtons second law: force (f) = mass (m) * acceleration (a)

shuffle to isolate acceleration (a)

acceleration (a) = force / mass = -10 000 / 1 000 = - 10 (m / s) / s

.

now find (braking) distance (s):

use v^2 = (u^2 ) + (2 * a * s)

shuffle to isolate s

s = (v^2 - u^2) / (2 * a)

s = - 4 900 / -20

s = 245 metres

.

time (t) to stop:

use v = u + a * t

shuffle to isolate t

t = (v - u ) / a

t = - 70 / - 10

t = 7 seconds

.

note: these calculations ignore rolling and air resistance, which are additional to the braking force.

What are some new facts about Sir Isaac Newton?

Isaac Newton had a kidney Problem, that's he died.

Isaac Newton died in Kensington, a place in England.

Isaac Newton discovered gravity, by two apples, one falling on his head, the other ' he was sitting by the window when he saw, and apple drop down to the ground'.

Who is Isaac Newton and what did he discover?

Isaac Newton was a renowned mathematician, physicist, and astronomer from England who lived in the 17th century. He is best known for his discovery of the laws of motion and universal gravitation, which laid the foundation for classical mechanics. Newton also made significant contributions to calculus and optics, among other fields.

When did Sir Isaac Newton discover the third law of motion and how?

he saw an apple fall and was curious about how that worked and discovered that gravity had something to do with it then he farted and wondered if gravity had something to do with the it moved around in the air but then he found out that's called diffusion and that farts really smell bad when you are under a blanket because the stink stays under then when you move the blanket a big green puff of smoke comes out with the fart and stinks worse than it did when it first came out then it starts to get stale

What is facts about newton's first law of motion?

Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This law describes the concept of inertia, which is the tendency of an object to resist changes in its motion. In practical terms, it means that objects will continue moving at a constant velocity or stay at rest unless a force is applied to change their state.
