Newton’s first law (law of inertia) This law states that “A body continues in its state of rest or uniform motion unless an unbalanced force acts on it”. The mass of a body is a measure of its inertia. Inertia is the property that keeps an object in its state of motion and resists any […]

Definition of Simple Machine A machine is a tool or device that makes work easier. It is defined as a tool which uses force applied (effort) at one point to overcome another resisting force (effort) at another point. Examples of machine include: a plier, the human arm, a gear, a pulley etc. Types of
Introduction Refraction is the change of direction of light rays as they pass at an angle from one medium to another of different optical densities. Exp. To investigate the path of light through rectangular glass block. Apparatus: – soft-board, white sheet of paper, drawing pins (optical), rectangular glass block. Procedure Fix the white plain paper on

Fluid in physics refers to liquids and gases. To study fluid flow we have to make the following assumptions: We consider fluids to be incompressible We assume that they have little or no internal friction or viscosity. Streamline and turbulent flow. The path followed by a small element of a moving fluid is called
Meaning of Radioactivity Radioactivity is the spontaneous disintegration or breaking down of the nucleus of an atom which makes it give out or emit radiation. Any element that disintegrates spontaneously and release rays us called a radioactive element Discovery of Radioactivity Radioactivity was discovered by a French physicist called Henri Becquerel in 1896. He

Electricity is the flow of electric current. Electric Current is the continuous flow of charges (electrons). It is also the rate of flow of charges. Electricity has several applications in the modern day society.

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 discovery brought about the development of electric bells, electric motors, telephone receivers and radios. Determining the direction of the lines of force. The direction of

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 scales; main scale and vernier scale. Outside jaws are used to measure both lengths and external diameters, inside jaws for measuring internal diameters while the tail
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 be sustained. Sources of continuous currents. In this process work is continuously done in moving electrons against a repulsive force. A device in which the potential difference is

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 therefore known as electrostatic charge or static electricity. The law of charges – types of charges There are two types of charges i.e. negative and positive charges. The
