Web7.11. The quantity 1 2 mv 2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. ( Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.) In equation form, the translational kinetic energy, KE = 1 2 mv 2, 7.12. WebIn a standard coordinate system (with x oriented to the right), the sum of horizontal forces for the top block is. F − F s f = m 1 a. and for the bottom block. F s f = m 2 a. where F s f is the force of static friction. Solving for a in these two expressions, and then equating them, gives. F = ( m 1 + m 2) F s f m 2.
