Potential energy is the stored energy in an object due to its position or configuration. It is primarily associated with gravitational force, elastic materials, and electric charges. The higher an object is positioned or the more it is stretched, the ...
Speed is a scalar quantity that measures how quickly an object moves. It is defined as the distance traveled per unit of time. Speed can be constant or variable, depending on the motion of the object. Common units of speed ...
The joule is the SI unit of energy, work, and heat. It is defined as the amount of energy transferred when a force of one newton acts through a distance of one meter. The joule is also used to measure ...
Momentum is the quantity of motion possessed by a moving body, determined by the product of its mass and velocity. It is a vector quantity with both magnitude and direction and is conserved in isolated systems during collisions or interactions, ...
Linear momentum is the product of a body’s mass and velocity, representing the quantity of motion. It is a vector quantity, having both magnitude and direction. Momentum is conserved in isolated systems, making it crucial in understanding collisions and dynamics. ...
Collisions occur when two or more bodies come into contact, resulting in an exchange of momentum and energy. They can be elastic, where kinetic energy is conserved, or inelastic, where kinetic energy is not conserved. Understanding collisions is essential in ...
The direction of motion refers to the path along which an object moves. It is determined by the object’s velocity vector, indicating both speed and the angle at which it travels. Understanding the direction of motion is essential in analyzing ...
Work, energy and power are fundamental concepts in physics. Work is done when a force causes displacement. Energy is the capacity to perform work, existing in forms like kinetic and potential energy. Power is the rate at which work is ...
Force is a physical quantity that causes an object to change its state of motion or rest. It is a vector quantity characterized by both magnitude and direction. Forces can be categorized as contact forces and non-contact forces such as ...
