Is that product of force and power on LHS? If yes, the equation looks dimensionally incorrect.REVIANNA said:P∗Fnet=((dK)/(dt))P*F_net=((dK)/(dt))

Actually, if you solved dK/dt first, you'll get power.
Then I believe answer is a couple of steps away. Good luck..REVIANNA said:so sorry ,actually the F_net was written as the subscript P which not their product
this makes complete sense now
##P_F=(dK/dt)##
Power is directly proportional to net force. This means that as the net force increases, the power also increases. This relationship can be mathematically represented by the formula P = F x v, where P is power, F is net force, and v is velocity.
Power is the rate at which work is done, so it determines how quickly an object can change its motion. A greater power means the object can accelerate faster or perform work in a shorter amount of time. This is why powerful machines can move or lift heavy objects more quickly than weaker ones.
The standard unit of power is the watt (W), which is defined as one joule per second. Other common units include horsepower (hp), which is often used to measure the power of engines, and kilowatt (kW), which is used to measure larger amounts of power such as in electricity generation.
No, net force and power are not the same thing and cannot be equal. Net force is a vector quantity that describes the overall force acting on an object, while power is a scalar quantity that describes the rate at which work is done. They have different units of measurement and represent different aspects of an object's motion.
Friction is a force that opposes motion, so it can decrease the power associated with net force. This is because some of the energy produced by the net force is lost due to friction. In order to maintain a constant power output, the net force must increase to compensate for the loss of energy to friction.
