This worksheet is for use in GCE Physics, both AS and A Level. It will help the students to achieve the following learning objectives from Edexcel 2015 Physics specifications - 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 - be able to use nλ = d sinθ for a diffraction grating 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.

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

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. 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.

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.

Big Bang theory and Red shift

Topic - Electromagnetism

This worksheet checks the understanding of accuracy and precision of single and multiple measurements in Physics.

This worksheet checks the understanding of greenhouse effect of the earth’s atmosphere in terms of how the long infrared waves and short visible light waves interact with the atmospheric gases using a PhET simulation.
