Effects Of Force On An ObjectA push or a pull acting on an object is called force. The SI unit of force is newton (N). We use force to perform various activities. In common usage, the idea of a force is a push or a pull.  Figure shows a teenage boy appl…

Force of FrictionIf the switch off the engine of car it will stop after moving a certain distance. It means that some retarding force is acting on the car which stops it. The force opposing the motion of the car is called “force of friction”.The frictio…

What Is The Normal ForceThe external agent which tends to set a body in motion or which changes the speed and direction of motion of a body or which can change the shape of a body is called force. SI unit of force is Newton.Types of Forces: (a) Non Cont…

How Do You Measure Density\(\text{Density}=\frac{\text{Mass}}{\text{Volume}}\text{    or   d}=\frac{\text{M}}{\text{V}}\)SI unit of density is kg/m3 and CGS unit of density is g /cm31 gm/cm3 = 1000 kg/m3Different substances have different densities whic…

What Is MomentumEvery moving object has momentum. However, the momentum of a timber lorry is very much bigger than that of a cyclist, despite them moving at the same speed.The product of mass and velocity is called ‘momentum‘. \(\text{i}\text{.e}\text{. …

Newton’s Laws Of Motion(A) Newton’s First Law of MotionA body can not change its state of motion by itself. If the object is at rest it will remain at rest and if it is in uniform motion, it continues to be in motion unless some external force is applied…

Law of Conservation of MomentumAccording to law of conservation of momentum “if there is no force acting on a system, the momentum of the system remains unchanged.”Generalizing the situation ” if a group of bodies are exerting force on each other, their…

Impulse of ForceFrom the previous section, you have seen that Newtons Second Law can be summed up by the formula F = ma.When a net force acts on a body, it accelerates in the direction of the force. By definition, acceleration, a is the rate of change i…

How Do You Find Buoyant ForceBuoyancy When a body is immersed in a liquid, the liquid exerts an upward force on the body called as the ‘upthrust‘ or ‘buoyant force.’Factors affecting upthrust: 1. Larger the volume of the body submerged in the liquid, gr…
