The net work equals the sum of the work done by each individual force. Strategy and Concept for (b) The forces acting on the package are gravity, the normal force, the force of friction, and the applied force.
WebKinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector. So a tennis ball thrown to the right with a velocity of 5 m/s, has the exact same kinetic energy as a tennis ball thrown down with a velocity of 5 m/s.
WebMar 26, 2015 · Since the kinetic energy is always positive, it is possible that the total energy of the particle can be negative, zero, or positive.
