Section 3: Dynamics (5059 PHYSICS GCE ORDINARY LEVEL (2014))

Candidates should be able to: 

(a) apply Newton's Laws to: 

(i) describe the effect of balanced and unbalanced forces on a body 
(ii) describe the ways in which a force may change the motion of a body 
(iii) identify action-reaction pairs acting on two interacting bodies 
 

(b)  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)

(c)  solve problems for a static point mass under the action of 3 forces for 2-dimensional cases (a 
graphical method would suffice) 

(d) recall and apply the relationship resultant force = mass × acceleration to new situations or to solve 
related problems 

(e) explain the effects of friction on the motion of a body
