Hey all, this is a group for talking about our favorite secret trails on the north shore, Squamish, and whistler. The intent is to relay trail conditions for trails not on Trailforks, discuss access to newcomers, and post photos of some of our favorite features on the trails!

Awesome idea - let me start. I cant wait to share all the amazing info about secret trails, but I will have to talk in code - I hope you understand.
A constant force, acting on a particle of mass m, will produce a constant acceleration a. Let us choose the x-axis to be in the common direction of F and a. What is the work done by this force on the particle in causing a displacement x? We have, for constant acceleration, the relations a = ( V - v ) / t and x = ½ ( V + v ) t. Here v is the particle's speed at t = 0 and V is its speed at time t. The the work done is W = F x = m a x = m ( ( V - v ) / t ) ( ½ ( V + v ) ) t = ½ m V² - ½ m v². We call one-half the product of the mass of a body and the square of its speed the kinetic energy of the body. If we represent kinetic energy by the symbol K, then K = ½ m v². We may then state the above equation in this way: The work done by the resultant force acting on a particle is equal to the change in the kinetic energy of the particle.
