Ch3+Forces+and+Pressure+a

You can make use of the slides to see the lesson material = = =Forces Learning Outcome= Candidates should be able to: (a) describe the effect of balanced and unbalanced forces on a body (b) describe the ways in which a force may change the motion of a body (c) identify forces acting on an object and draw free body diagram(s) representing the forces acting on the object (for cases involving forces acting in at most 2 dimensions) (d) recall and apply the relationship resultant force = mass x acceleration to new situations or to solve related problems (e) explain the effects of friction on the motion of a body
 * How forces act together to form a resultant force
 * List and explain how the forces can change the shape, size, motion of the body.
 * Adding of forces through the use of scale diagram
 * Making use of the resultant force to relate and find the mass and acceleration of the object
 * How friction is used as part of the question to find the resultant force, so as to apply Newton's 2nd law.
