Units of Force
The unit of force in the S.I. is 'newton'. (Symbol : N) One newton is that force which when acting on a body of mass 1 kg produces a uniform acceleration of 1 m s - 2 in its own direction. The C.G.S unit of force is 'dyne'. One dyne is that force..
Balanced And Unbalanced Forces
Balanced And Unbalanced Forces - The figures show a block of wood on a table. When the block is pulled at point A, it begins to move towards the left and if the block is pulled at the point B it moves towards the right. Example of Balanced Forces In a game of tug of war when bot..

Another unit of force by which the magnitude of force can be understood and gauged, is the gravitational unit of force. A gravitational unit of force is that force with which the Earth attracts a body of unit mass towards its centre. A gravitational..
Origin of London forces
fig 1.33 - Origin of London forces It may be noted that London forces are quite weak. The strength of London forces lies below 12.5 kJ mol - 1 . The magnitude of these forces determines the melting and boiling points of various substances. Although these ..
Driving force as the overall tendency for a process
It can be summarized that the spontaneous processes occur because of the two tendencies: (i) Tendency of a system to acquire a state of minimum energy. (ii) Tendency of a system to acquire a state of maximum randomness. The overall tendency for a process to take place by itself is called the drivi..
Gravitational Force between two Light Objects
Let us now calculate the force of gravitation existing between two unit masses separated by a unit distance. m 1 = 1 kg m 2 = 1 kg d = 1m G = 6.6734 x 10 - 1 1 Nm 2 /kg 2 This is a very weak force. To find Force existing between two objects of masses 60kg and..

"American football team needs to score not less than 3 goals over Germany to win the match." Which of the following inequalities represents this statement, if G stands for the number of goals? => G ≥ 3 or G > 3 or G ≤ 3 or G < ..
Acceleration due to Gravity 'g'
Bodies allowed to fall freely were found to fall at the same rate irrespective of their masses (air resistance being negligible). The velocity of a freely falling body increased at a steady rate i.e., the body had acceleration. This acceleration is called acceleration due to gravity - 'g'..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
The tutors are amazing. They are very committed in helping students solve the questions and explains all the steps beautifully. So 5 stars for Tutor Vista.
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
