TURNING EFFECT OF A FORCE TURNING EFFECT OF A FORCET:urning effects The turning effect of a body is called the moment of that force. The turning effect produced depends on both the size of the force and the distance from the pivot.…

MEASUREMENT II FORM TWO MEASUREMENT II FORM TWO:Measuring length using vernier callipers. Vernier callipers is used when higher accuracy in measurement is required and this cannot be done using a metre rule. Vernier callipers has two…

MAGNETISM FORM TWO MAGNETISM FORM TWO:Introduction Magnets are substances that are able to attract and hold items. Lodestone is the only known natural magnet which was discovered by the Chinese 2,000 years ago. Other magnets produced…

EQUILIBRIUM AND CENTRE OF GRAVITY. Centre of gravity Centre of gravity or C.G is the point of balance of a body in which the total weight of the body seems to act through. For regular shaped bodies the C.G is at the geometric centre…

CELLS AND SIMPLE CIRCUITS. CELLS AND SIMPLE CIRCUITS:Introduction Work done per unit charge is called electrical potential. Current is the flow of charge. For current to be continuous, potential difference between the two points must…

ELECROSTATICS I FORM ONE ELECROSTATICS I FORM ONE:ELECROSTATICS I. Some substances get charged when rubbed against other substances i.e. nylon, plastic, paper etc. the charge acquired stays within the body i.e. it does not move and…

THERMAL EXPANSION FORM ONE THERMAL EXPANSION FORM ONE:Introduction Temperature is the degree of hotness or coldness of a body. Both Celsius scale (0C) and Kelvin scale (thermodynamic scale) are used to measure temperature. The Kelvin…

PRESSURE FORM ONE PRESSURE FORM ONE:PRESSURE Pressure is defined as the force acting normally (perpendicularly) per unit area. The SI units for pressure is newton per metre squared (N/m2). One Nm-2 is known as one Pascal (Pa).…

MAGNETIC EFFECT OF AN ELECTRIC CURRENT. Introduction: Oersted’s discovery. Hans Christian Oersted discovered the magnetic effect of a current in 1819. The direction of the field is dependent on the direction of the current. This…

WAVES I FORM TWO WAVES I FORM TWO: Wave A wave is simply a disturbance that moves through a medium. Other waves do not require a medium to travel i.e. they can travel in a vacuum, are known as electromagnetic waves e.g. radio, X-rays,…
