Chapter 6 Work and Kinetic Energy
... This will be important when we discuss conservation of energy in the following section. Example 6.2. A farmer hitches her tractor to a sled loaded with firewood and pulls it a distance of 20 m along ground. The total weight of sled and load is 147000 N. The tractor exerts a constant 5000 N force at ...

VIRTUAL PARTICLES by Robert Nemiroff
... If forces result from exchanging virtual particles, and their corresponding real particles always have positive mass, how can any force be attractive? Virtual particles can carry negative momentum. Interference with other virtual photons (of the other particle) can determine attractive or negative m ...

PRE-LAB FOR CONSERVATION OF ENERGY
... In the lab on work and energy, we defined the kinetic energy associated with the motion of a rigid, non-rotating object: KE = 12 mv 2 where m is the mass of the object and v is its speed. In this lab, we will explore the concept of potential energy. Suppose you lift an object at a slow, constant spe ...
