Boland, John, Executive Vice President has reference to this Academic Journal, PHwiki organized this Journal Resultant Forces31 August, 2011KeywordsBalanced, Unbalanced, Resultant, Stationary, Positive , NegativeAll students should be able to: Add in addition to subtract with positive in addition to negative numbers.Most students should be able to:Find the resultant as long as ce acting on an object when there are two as long as ces acting in the same direction or in opposite directions.Describe how the resultant as long as ce will affect the movement of the object.Describe examples where an object acted on by two as long as ces is at rest or in uni as long as m motion.Some students should be able to:Describe examples where the motion of an object acted on by two as long as ces along the same line is changed by the action of the as long as ces.Underst in addition to that as long as ces always come in pairs that are the same type, equal in addition to opposite.OutcomesWhat is:A) 2+20B) 34+678C) 34-34D) -4-4E) -12-(-13)starter

If there are no as long as ces acting on an object which is not moving, it will stay at rest. or if it was already moving at a steady state in a straight line, it will continue to move in a straight line as be as long as e.So to start something moving

or speed it up, slow it down or stop it or change its direction A as long as ce must be applied.

Introducing balanced as long as cesWhat is Newtons first lawif the object is stationary, it will remain stationaryif the object is moving, it will continue to move at the same speed in addition to in the same direction.If the resultant as long as ce acting on an object is zero, all the as long as ces are said to be balanced.This as long as ms the basis of Newtons first law of motion, which states:Your teacher in addition to your classmates will demonstrate these:Air Track Tug of war Your task will be to draw diagrams of these demonstrations to show how the resultant as long as ces can make objects: Accelerate Decelerate Change directionAnd what type of as long as ces are necessary as long as an object to: Stay stationery Or travel at a constant speedDemos  1st Law

A as long as ce cannot exist on its own  there is always a second as long as ce acting against it.This as long as ms the basis of Newtons third law of motion states, which states:What is Newtons third lawThese pairs of as long as ces that act between two objects are sometimes called actionreaction pairs.Actionreaction pairsWhat as long as ces are acting on Mels computerThe computer is pulled downwards by the as long as ce of gravity in addition to causes it to have weight.Newtons 3rd Law pairsAlthough the table exerts an equal in addition to opposite as long as ce pushing upwards on the computer. This is not weight.So this is not a Newtons 3rd Law pair.

What as long as ces are acting on Mels computerThe computer is pulled downwards by the as long as ce of gravity in addition to causes it to have weight.The computer pulls the Earth towards it with the same as long as ce as it gets pulled towards the Earth. The Newtons 3rd Law pair is shown above.Newtons 3rd Law pairsAlthough the table exerts an equal in addition to opposite as long as ce pushing upwards on the computer. This is not weight.Your teacher in addition to your classmates will demonstrate the:Methane RocketTug of war (skateboards)Your task will be to draw diagrams of these demonstrations in addition to a description of how the as long as ces here are equal in addition to opposite.Demos – 3rd LawQuestion:Under what conditions is water most likely to spill from a bowl when it is carried is a relay raceHow can you explain thisPass the water relay

Pass the Water relayOnce completed  do these tasks in your exercise book1) Describe the aim of the relay2) What do you think will happen3) Describe what you did  draw a diagram to help4) What were your results (what happened)5) Was this what you expected to happen  explain why6) How could you make the results easier to see (better)How well will you participateNOW: Use some words below more than once to help copy in addition to complete:If you add all the as long as ces together on an object this is called the as long as ce.Newtons first law says that an object will remain . or go at a constant . unless there is a . as long as ce on it. If a resultant as long as ce acts on an object it will change or change its Newtons third law says that If object A exerts a as long as ce on object B, then object B exerts an equal but . as long as ce on object A.stationary speed balance direction opposite frictional resultantTurn to the person next to you in addition to tell them 2 things you have learnt today in addition to 1 way that you learnt it.Plenary
