A satellite is an object that orbits a larger object, most commonly a celestial body. It can either be a natural satellite or an artificial satellite: Natural satellites are Objects that orbit a larger object in space naturally, such as the moon orbiting Earth or Earth orbiting the sun. Artificial satellites are Objects that are…
Rockets are vehicles that use external combustion engines (Jet propulsion) to accelerate without using any surrounding air. These work by generating an impulse by the high-speed ejection of the fuel mass. Apogee & Perigee: Types of Orbits: Posigrade: Along the motion of the earth. Retrograde: Opposite to the movement direction of the earth. Low Earth…
The fact that amber rubbed with wool or silk cloth attracts light objects has been known since ancient times throughout the world. We have seen lightning strikes, but both of them are connected was never known until modern times. In this chapter, we will establish the basics of the Electricity. Electric charges Very simple experiments…
Fluids are substances that can flow and do not have a fixed shape. They include liquids and gases. Here, we might ask what it means for a substance to flow? The property of flow refers to the characteristics of an object to show no resistance to the shear stress. Shear stress can change the shape…
Thermodynamics is the study of energy, work, and heat and the relationship between them. It deals with the macroscopic behaviour of matter and energy, explaining phenomena such as heat engines (Such as refrigerators, and air-conditioners) and the behaviour of gases. In this chapter, we will cover the thermal properties of matter, Heat flow and energy…
Quantity Name Symbol Definition Length Metre m The metre is the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458 of a second. (1983) Mass Kilogram kg The kilogram is defined by the fixed numerical value of the Planck constant, which is 6.62607015 × 10−34 kg⋅m2⋅s−1. Time Second…
Mechanics in physics is the branch that deals with the motion of objects and the forces acting on them. It includes concepts like displacement, velocity, acceleration, and force. Mechanics is divided into kinematics (study of motion) and dynamics (study of forces), forming the foundation for understanding physical systems. Kinematics Kinematics is the branch of physics…
Classical physics refers to the branch of physics that deals with the study of matter, energy, and the fundamental forces in the universe, primarily in contexts where quantum effects are negligible. It emerged as the dominant framework for understanding the physical world before the development of modern physics in the 20th century. Origins of Classical…
