The energy of motion is called: Kinetic energy. potential energy, inertial energy. Power. In an inelastic collision: momentum is conserved. kinetic energy is conserved, both (a) and (b). If the velocity of a moving object is doubled and its mass is cut in half, the kinetic energy of the object is; remains the same, doubled quadrupled, cut in half. When the net work done on an object is speed of the object is me on an object is zero; the...

11.9. As shown in the figure, an object of charge Q, and mass m moves near a stationary object with charge Q2. Assume the mass and the charges are constants, and assume the objects are surrounded by free space. The kinetic energy of the moving object is converted to or from energy stored in the electric field between the objects. The kinetic energy of the moving object is given by m). The energy of the electric field is given by...

Consider an object in free fall starting at position x_i=y_i=0 and ending up at some arbitrary final point (x_f,y_f). The initial velocity is v_i->=(v_x, v_yf)- note that the x-component of velocity is constant because we are in freefall. a)draw the free body diagram for the object. c) show that the work done by gravity is going from (0,0) to (x_f,y_f) is W=-mg delta y=-mgy_f. c)show that the change in kinetic energy is deltaK = 1/2 m(v_yi^2- v_yt^2). d)use the work-energy...
