Question

6. The work done by a force is described by the equation, W = F S cos 0. For which value of O is the work done
thrown vertically upwards. What is the kineti
maximum?
7. A body of mass m falls freely from a height h. What will be its kinetic energy just before it touches the ground?
8. What is the SI unit of power? Define it.
​

Answer 1

Answer:

Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 - 1819).
