Effects Of Force On An Object A 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 applying a force to push a ball and a young boy applying a force to pull a kite. The action of a force can … [Read more...] about What Are The Effects Of Force On An Object

What Is The Force Of Friction
Force of Friction If 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 frictional force is tangential to the surface in contact and always in a direction opposite to the direction of motion of the … [Read more...] about What Is The Force Of Friction
What Is The Normal Force
What Is The Normal Force The 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 Contact: These are the forces in which contact between two objects is not necessary. Gravitational force between two … [Read more...] about What Is The Normal Force
How Do You Measure Density
How Do You Measure Density SI unit of density is kg/m3 and CGS unit of density is g /cm3 1 gm/cm3 = 1000 kg/m3 Different substances have different densities which gets affected by temperature. Respective density of a substance decreases on heating due to the expansion of the substance. Water has anomalous expansion. When water is cooled at 4ºC, its volume … [Read more...] about How Do You Measure Density
How Do You Solve For Momentum
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'.Unit: SI unit of momentum is kg-m/s. It is a vector quantity.Also Read About: Principle of Conservation of Momentum Activity … [Read more...] about How Do You Solve For Momentum
