Introduction:

Anything that occupies space and has mass is called matter. Matter can be divided into two types.

  1. Pure substance: It consists single types of particles which are identical and same characteristics.
  2. Mixtures: Mixture contains two or more different kind of particles or atoms. The particles show their individual characteristics.

Mixtures are of two types.

  • Homogeneous mixtures: A mixture is said to be Homogeneous if all the particles in mixture is mixed properly and they cannot be separated by simple physical process.
  • Heterogeneous mixtures: A mixture is said to be Heterogeneous if all the components of the mixture are not uniformly mixed and they can be separated easily.

Mathematical representation of momentum of an object

Suppose an object having mass m has an initial velocity u and after certain time t it attains a velocity v. Now momentum P1=mu and P2=mv So change in momentum =P2-P1=mv-mu =m(v-u) So the rate of change in momentum =m(v-u)/t Now momentum is proportional to the applied external force. So, F=m(v-u)/t We... read more

Suppose an object having mass m has an initial velocity u and after certain time t it attains a velocity v.

Now momentum P1=mu and P2=mv

So change in momentum

=P2-P1=mv-mu

=m(v-u)

So the rate of change in momentum

=m(v-u)/t

Now momentum is proportional to the applied external force.

So,

F=m(v-u)/t

We know that acceleration=(v-u)/t

Therefore, F=m × a

In other word Force=mass×acceleration

Law of Motion physics class 9 by sunil Sir

Law of motion

 

Sir Isaac Newton was one of the greatest scientists and mathematicians that ever lived. He was born in England on December 25, 1643. He was born the same year that Galileo died. He lived for 85 years.

Isaac Newton was raised by his grandmother. He attended Free Grammar School and then went on to Trinity College Cambridge. Newton worked his way through college. While at college he became interested in math, physics, and astronomy. Newton received both a bachelors and masters degree.

While Newton was in college he was writing his ideas in a journal. Newton had new ideas about motion, which he called his three laws of motion. He also had ideas about gravity, the diffraction of light, and forces. Newton's ideas were so good that Queen Anne knighted him in 1705. His accomplishments laid the foundations for modern science and revolutionized the world. Sir Isaac Newton died in 1727.

 

Newton gave Three Laws of Motion.

 

 

According to Newton's first law...

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

This law is often called 
"the law of inertia".

 

What does this mean?

This means that there is a natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain this state of motion.






 

 

 

 

 

eg: Let's study the "skater" to understand this a little better.

 



This law is the same reason why you should always wear your seatbelt.




 

 

 

 

 

 

 

According to Newton's second law...

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

What does this mean?

Everyone unconsciously knows the Second Law. Everyone knows that heavier objects require more force to move the same distance as lighter objects.

     
     

However, the Second Law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematical equation:



or 
FORCE = MASS times ACCELERATION

This is an example of how Newton's Second Law works:

Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car.



Answer = 50 newtons

According to Newton's third law...

For every action there is an equal and opposite re-action.

 

What does this mean? 

This means that for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard. 



Let's study how a rocket works to understand
Newton's Third Law.

 

The rocket's action is to push down on the ground with the force of its powerful engines, and the reaction is that the ground pushes the rocket upwards with an equal force.


 

 

UP, 
UP, 
and 
AWAY!

 

Thank you

The number of cycles covered by a moving body per unit of time is called it's frequency. In other words if a body is moving in a circular motion then number of cycles covered by it per second is it's frequency.

Generally metal have high melting point than room temperature and so all metal like sodium, potassium,stonsium, magnesium zinc are high melting point.iron cupper nickel silver and gold have also very high melting point.there is exception, Mercury exist in liquid in room temperature.it is possible due to formation of ionic lattice.

Usually non metal have very low melting point so the room temperature exceed the melting point and it is found in liquid state.like O2( dioxygen),N2(Nitrogen),C2(chlorine gas).

Molar mass of N2 is 28 (since atomic weight of nitrogen is 14 and for N2=14*2) So mass of 1 mole of N2 is 28g. Therefore, mass of 0.5 mole is 28/2=14g
