Friction and its laws

Hey we know that there are so many dissipative forces are present around us which opposes our efforts e.g. imagine that you want to slide a heavy table on irregular surfaces, in this case you will try it very hard as the irregularities present on the surface opposes your action. This force present here is […]

Motion of a car on a level road

Hello dear students we know that the centripetal force and centrifugal force plays very important in explanation of circular motion. The force which acts on a particle along the radius towards the Centre of the circle and which keeps the particle moving along the circular path is called centripetal force. According to Newton’s 2nd of […]

Newton’s second law of motion

Hello dear students we have learnt that, the tendency of body to resist change of its state of motion is termed as inertia of motion. External force is required to change the state of from motion to rest. When object is in motion, along with mass, velocity also contributes inertia. Here the product of mass […]

Elastic and Inelastic Collisions

Hello everyone in this article we are going to discuss the interesting and important concept of mechanical physics i.e. collision. Consider the following examples, Striking of one marble on another in circle during marble play Striking the tennis ball on the wall Head on strike of vehicles during accident All above are the examples of […]

Conservation of Mechanical Energy

Dear students in 9th and 10th standard we have learnt about the energy, the forms of energy. We categorised the mechanical energy in to following forms: Kinetic energy, Kinetic energy is the energy that possesses by the body due to its motion. If body of mass ‘m’ moves with the velocity of ‘v’ then kinetic […]

Concept of Potential Energy

Dear students in 9th and 10th standard we have learnt about the energy, the forms of energy and law of conservation of energy. We categorised the mechanical energy in to following forms: 1.) Kinetic energy, Kinetic energy is the energy that possesses by the body due to its motion. If body of mass ‘m’ moves […]

Work Energy Theorem

Dear students in 9th and 10th standard we have learnt about the energy and law of conservation of energy. According to law of conservation of energy,’ Energy can neither be created nor be destroyed can be converted from one form to another form’. Some of the conditions where this can be easily observed are, 1) […]

Scalar Product of Two Vectors

Dear students we know that vectors are used to explain the important terms like force, velocity, acceleration etc which has magnitude along with the direction. To discuss the quantities like work, electric flux, magnetic flux scalar product of vectors is used in which magnitude of vectors only taken. Let’s learn the vector product of vectors […]

Vector product of two vectors

Dear students we know that vectors are used to explain the important terms like force, velocity, acceleration etc which has magnitude along with the direction. We have learnt about the right hand screw rule used to explain the direction of angular displacement vector and the radius vector for the particle performing the circular motion Let’s […]

Angular velocity and its relation with linear velocity

Hello dear we know that the particle performing rotational motion can be discussed completely with angular velocity, angular acceleration etc. The motion of particle along circumference of circle is termed as circular motion. The displacement of particle along circumference of circle is considered in terms of angle and radius vector. Angular displacement Angle traced by […]
