XI A Science Ch-9 Force and Laws Of Motion
Force and Laws Of Motion Topic taught-23 August 21 Introduction to Force A force is an effort that changes the state of an object at rest or at motion. It can change an object’s direction and velocity. Force can also change the shape of an object. To know more about Force, visit here. Balanced and Unbalanced Forces When balanced forces are applied to an object, there will be no net effective force acting on the object. Balanced forces do not cause a change in motion. Unbalanced forces acting on an object change its speed and/or direction of motion. It moves in the direction of the force with the highest magnitu Push or pull of an object is considered a force. Push and pull come from the objects interacting with one another. Terms like stretch and squeeze can also be used to denote force. In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing the state of rest

Date- 12/8/21 Topic - Is Matter around us pure Topic taught- Introduction to Separation Separation of components of a mixture Heterogeneous mixtures can be separated into their constituents by simple physical methods. Methods include: handpicking, sieving, filtration. Separation of Two Immiscible Liquids Separation of a mixture of two immiscible liquids Separation of a mixture of two immiscible liquids is done by using a separating funnel. Applications: To separate a mixture of oil and water, in the extraction of iron from its ore. Centrifugation Centrifugation uses centrifugal force for the separation of two liquids in a mixture. Here, a denser component of the mixture migrates away from the axis, and lighter component migrates towards the axis. Sublimation Sublimation is the transition of a substance from solid phase to gaseous phase without changing into liquid phase. Example : Naphthalene balls undergo sublimation. Chromatography Chromatography is used to separate the dif
