Mechanics

What is Centrifugal Force? Centrifugal force is a fictitious force ( also called a pseudo force ) which is experienced by an object moving in a curved or circular path. It is directed away fromRead More →

What is called Centripetal Acceleration? Uniform circular motion is an accelerated motion. When a particle is in uniform circular motion, its speed remains constant but its velocity changes continuously due to the change in directionRead More →

What is called Displacement Time Graph? Characteristics of motion of a moving body can be quickly understood with the aid of graphs. For this purpose, the position, velocity and acceleration of a moving body areRead More →

What is called an Acceleration? During the course of journey of a moving object, its speed or velocity may change several times. Each time a change in speed occurs, it is due to acceleration ofRead More →

What is called an Equilibrium? Equilibrium is the condition of a system or body in which its state of rest or motion is not changing with time. It is called stable equilibrium in studies ofRead More →

What is called a Rolling Motion? Rolling motion is particular type of motion in which a circular or spherical object makes a combination of rotation and translation. For example, if a marble sphere is thrown onRead More →

What is called a “Torque”? Torque is the effect of a force that can cause an object to rotate about an axis. A force produces linear acceleration in an object which is in linear motion. InRead More →

What is called a Projectile Motion? When a particle is thrown in space near the earth’s surface then it moves along a curved path under the influence of gravity, then its motion is called aRead More →

What is called “Motion in a Vertical Circle”? When a particle is made to move along a circular path in a vertical plane, the motion is a non uniform circular motion. This is due toRead More →

What is Angular Momentum? Momentum of a moving body is defined as the product of the mass and velocity of the body. It gives an idea about the energy capacity that a moving body possesses.Read More →

What is called a “Uniform Circular Motion”? Curvilinear motion is the motion of an object along the circumference of a circular path or a curve of any shape or rotation of an object along aRead More →

What is called Relative Velocity? The relative velocity is defined as the velocity of an object with respect to an observer on the same frame or another moving or stationary frame. It is the rate ofRead More →

What is called Linear Momentum? Linear Momentum of a moving body is defined as the product of the mass and linear velocity of the body. It gives an idea about the energy capacity that aRead More →

What are Newton’s Laws of Motion? Sir Isaac Newton (1642-1727) made a systematic study about motion of bodies and stated three laws of motion which are called Newton’s laws of motion. Three Laws of motionRead More →

What are Kinematic Equations of Motion? The equations governing the motions of an object along a straight line path or a curved path are called Kinematic equations. The kinematic equations are derived from the theoriesRead More →
