Talk:A-level Physics/Forces and Motion/Force, work and power

Specification
From the OCR GCE Physics A specification. Tick with &#10004; when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.


 * 1) Understand that the weight of a body may be taken as acting at a single point known as its centre of gravity.
 * 2) Understand a couple as pair of equal parallel forces tending to produce rotation only.
 * 3) Define and use the moment of a force and the torque of a couple.
 * 4) Show an understanding that, when there is no resultant force and no resultant torque, a system is in equilibrium.
 * 5) Apply the principle of moments to solve problems involving forces acting in two dimensions.
 * 6) Define pressure.
 * 7) Recall and use the equation P=F/A
 * 8) Understand the concept of work in terms of the product of force and displacement in the direction of the force.
 * 9) Define the Joule.
 * 10) Recall and use the equation W=Fx, where F is a constant force along the direction of motion.
 * 11) Recall and use equations for kinetic energy Ek=½mv2 and change in gravitational potential energy ∆Ep = mg∆h.
 * 12) Relate power to work done and time taken.
 * 13) Define the Watt
 * 14) Recall and use the equation W=Pt (Work = Power x time).

moving "force"
I think the concept of force should be introduced in Dynamics, because in Kinematics, you are introduced to position, speed, velocity and acceleration without regard to the forces behind the movements, and then in Dynamics, you are introduced to forces of 1N as what accelerates a mass of 1kg at 1m/s^-2.

Force, work and power introduces you to the concept of work done or energy and how power relates to that.

So, basically, the contents of here will be moved to Dynamics --Krackpipe 22:41, 25 August 2005 (UTC)
