Reducing friction with ball bearings
Find two tin cans that have a deep groove approximately the top, such as paint cans. Lay marbles in single groove and invert the other can over the marbles to form a ball bearing. Place a book on top and note how simply the demonstration bearing turns. Oil the marbles and it will turn still more easily.
Why we are showing work done over a closed path is zero to prove that electrostatic forces are conservative
two forces at right angle with each other have a resultant of 58kN, If one of the forces is 40kN find the magnitude of the other forces
A simple calorimeter Small soup tins can be found which fit loosely into a 1lb. jam jar. If the top of the tin is cut off cleanly with a rotary type opener it serves as an good

Constant Acceleration 1-dimensional kinematics of a body undergoing constant acceleration. Involves visually integrating the acceleration and velocity graphs or visually differ
RESISTIVITY: R esistance may be defined as that property of a substance which opposes (or restricts) the flow of current (or electrons) through it. The practical as well as MK
sir, I am in class xii and i have to submit a project:working model on any topic in physics. so please help me figure this out
Q. An emf of 5 V is persuading when the current in the coil changes at the rate of 100 As-1. Find the coefficient of self induction. Solution: Induced emf e = - L dI/dt
Depending on the material of the resistance element, resistors are classified into linear resistors and non linear resistors. Majority of the resistors used in electronic circuits
Two bodies are moving in circular paths of equivalent radii. If the speed of the first body is twice that of the second, the centripetal acceleration of the first body is how
