Solution of Physics Numericals for class 9 (set 1 Q16)

Problem Statement A bullet of mass 50 g moving with an initial velocity of 100 m/s, strikes a wooden block and comes to rest after penetrating a distance 2 cm in it. Calculate: (i) Initial momentum of the bullet (ii)final momentum of the bullet (iii) retardation caused by the wooden block, and (iv) resistive force […]

Solution of Physics Numericals for class 9 (set 1 Q11)

Problem Statement A force acts for 10 s on a stationary body of mass 100 kg after which the force ceases to act. The body moves through a distance of 100 m in the next 5 s. Calculate (i) the velocity acquired by the body, (ii) the acceleration produced by the force, and (iii) the […]

Newton’s Second Law and equation of Force

Newton’s Second Law states that the rate of change of momentum of a body is directly proportional to the net force applied on it, and this change in momentum takes place in the direction of the applied force. Mathematically it can be stated this way: F∝ (mV-mU)/t. Here, F is the net force acting on the […]

Contact Forces between blocks – Application of Newton’s laws

Application of newton’s laws: Newton’s laws of motion give us concepts of force (first law), measurement of force with its equation (second law), and the reaction of force (3rd law). Today we will discuss an interesting topic of mechanics – the application of Newton’s laws. It will cover a few interesting applications of Newton’s Laws […]

Pseudo force in Physics-did you know this?

 What is a pseudo force? – Some forces are real, whereas others are not. Real forces have some physical origin, such as a gravitational pull, frictional force, or tension of the string. In contrast, fictitious force or pseudo force arises simply because the observer is in an accelerating or non-inertial frame of reference, such as […]

Newton’s Third Law of motion – concepts and examples

Newton’s third law of motion states that to every action there is an equal and opposite reaction. This means for every action or force exerted by the first object on the second object, there will be a reaction force that is equal in magnitude and opposite in direction to the action force. And this reaction force […]
