In physics, an impulse is defined as the change in momentum of an object over a period of time. It is given by the product of force and the duration of the force applied. Mathematically, it is expressed as: Impulse = Force × Time The impulse is a vector quantity, and its direction is the…
Mechanical energy is the sum of kinetic energy and potential energy of an object due to its position, motion, or both. Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy an object possesses due to its position or state of being. The total mechanical energy of…
The conservation of linear momentum is a fundamental principle in physics that states that the total momentum of a system of interacting objects remains constant, unless acted upon by an external force. In other words, if two objects interact with each other, the total momentum of the system before and after the interaction must be…
Static friction and dynamic friction are two types of frictional forces that act on objects in contact with each other. Static friction is the force that prevents an object from moving when a force is applied to it. It is a type of frictional force that opposes motion between two objects in contact with each…
In physics, a frame of reference is a coordinate system used to describe the position and motion of objects in space. When an observer is in a state of constant motion with respect to another observer, they are said to be in different frames of reference. A uniformly accelerated frame of reference is a frame…
Newton’s laws of motion are a set of three fundamental principles that describe the behavior of objects in motion, as formulated by the English physicist Sir Isaac Newton in the 17th century. They are as follows: These laws have been foundational in the development of classical mechanics and have been used to describe the motion…
A projectile is any object that is thrown, shot, or launched into the air, and that moves along a ballistic trajectory. Projectiles are subject to the force of gravity, which causes them to follow a curved path known as a parabola. The motion of a projectile can be described by its initial velocity, angle of…
Cartesian coordinates are a system of describing the position of a point in space using three numbers, typically denoted as (x, y, z). The x-coordinate represents the distance from the point to the yz-plane (a plane perpendicular to the x-axis), the y-coordinate represents the distance from the point to the xz-plane (a plane perpendicular to…
To determine the specific resistance of the material of a wire using a meter bridge, you will need the following equipment: Here are the steps to follow: You have now determined the specific resistance of the material of the wire using a meter bridge. What is Required General Specific resistance of the material of a…
Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. This relationship is often expressed as: I = V/R where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. To verify Ohm’s law…
