A mass M is hung from a spring. It is then pulled down slightly and allowed to vibrate vertically between P and Q. Which is correct? Energy at point P Energy at point Q A kinetic Kinetic B Kinetic Potential C Potential Kinetic D Potential Potential   The answer... ## GCE O level Physics- N2011/P2/A2- Energy Work & Power- Suggested Solution

By principle of conservation of energy, in an ideal world, when an object move from a higher position to a lower position, the loss in gravitational potential energy equals gain in kinetic energy. However, in a real world where there is friction, some energies are... ## GCE O Level Physics N2015/P1/Q7 – Suggested Solution

This is a suggested solution to the question in GCE O Level Pure Physics Paper 1, MCQ question 7. Suggested Solution The answer is A. That is, 800N.   Explanation Resultant Force, F = Driving Force – Frictional Force = ma Given : a = 2.5 m/s2 Therefore, F= 800kg... ## Suggested Solution : N2011/P1/Q9
