Question

For a particle, the instantaneous net power is P_net. Which statements are correct?

G1 Physics · Accepted Answer

P_net=dK/dt. Positive net power increases K and hence speed. Zero power only implies no instantaneous change of speed; acceleration may be perpendicular to velocity. Uniform circular motion is the standard example.
