MEANING OF PROJECTILE A projectile motion is one that follows a curved or parabolic path .It is due to two independent motions at right angle

BASIC DEFINITIONS Displacement: This is the distance traveled in a specified direction. It is a vector quantity. Its unit is metres Distance: This is the

CONCEPT OF SCALAR AND VECTOR QUANTITIES Physical quantities are divided into scalar and vector quantities. A scalar is one which has only magnitude (size) e.g.

POSITION The position of an object in space or on a plane is the point at which the object can be located with reference to

ELECTROMAGNETIC FIELD This is a field representing the joint interaction of electric and magnetic forces. It is exerted on charged particles. The force on a

PATTERNS OF MAGNETIC FIELDS Magnetic field pattern can easily be observed using iron fillings. The magnetic is put on paper and the iron fillings are

MAGNET AND ITS PROPERTIES A magnet is any material that is capable of attracting other pieces of the same material as well as pieces of
