<p>This worksheet tests the knowledge and understanding of acceleration, Newton’s first and second laws, equilibrium, free body diagram and frictional forces. It also includes numerical and graphical questions.</p>

<p>This worksheet requires a clear understanding of difference between distance traveled and displacement from the starting position. Mathematical skills needed are Pythagoras theorem and circumference of a circle.<br /> The questions include numerical problems with motion along a straight line in same and opposite direction, motion with ninety degrees turn and motion along parts or a full circle.</p>

<p>This worksheet assesses understanding of definitions of velocity and acceleration, their units and solving related numerical and graphical questions.</p>

This worksheet is for use in GCE Physics, both AS and A Level. <br /> It will help the students to achieve the following learning objectives from Edexcel 2015 Physics specifications<br /> - Understand what is meant by diffraction and use Huygens’ construction to explain what happens to a wave when it meets a slit or an obstacle<br /> - be able to use nλ = d sinθ for a diffraction grating<br /> Differentiation is evident as higher challenge questions are given in bold. Marks and space are provided as an indication to the students on structuring their answers generally following the A Level Board examination format.
