Velocity is the rate of change of an object’s displacement with time. It has both magnitude and direction, making it a vector quantity. Velocity can be uniform or non-uniform depending on motion. Its SI unit is meters per second and ...
A simple pendulum consists of a small heavy mass called a bob suspended from a fixed point by a light inextensible string. It swings back and forth in a periodic motion. The time taken for one complete oscillation depends on ...
Energy is the ability to do work. It exists in different forms like kinetic, potential, thermal, chemical, and electrical energy. It follows the law of conservation where it changes from one form to another but remains constant. Renewable and non-renewable ...
Angular frequency is the rate at which an object moves through an angle in circular motion or oscillation. It is denoted by ω and measured in radians per second. It relates to linear frequency as ω = 2πf. It plays ...
Simple harmonic motion is a type of periodic motion where an object moves back and forth along a fixed path. The restoring force is directly proportional to displacement and acts in the opposite direction. Examples include a pendulum and a ...
Harmonic motion is a type of periodic motion where an object moves back and forth around an equilibrium position. It includes simple harmonic motion with constant amplitude and frequency. Examples include a pendulum and a vibrating spring. This motion follows ...
Gas molecules are tiny particles that move randomly in all directions. They have high kinetic energy and weak intermolecular forces. Their movement depends on temperature and pressure. Gas molecules collide elastically with each other and container walls. This behavior explains ...
Molecular speeds of gases refer to the velocities of gas molecules in motion. They include the most probable speed, average speed, and root mean square speed. These speeds depend on temperature and molecular mass. Higher temperatures increase molecular speeds while ...
The kinetic theory of gases explains the behavior of gas molecules using assumptions about their motion and interactions. It states that gases consist of tiny particles in constant random motion. The theory describes pressure, temperature, and volume relationships based on ...
