Presentention on physics:power

It is defined by the formula:

$$P = \frac{W}{t}$$

where:

• $P$ is power
• $W$ is work done or energy transferred
• $t$ is the time taken

Alternatively, for an object moving at a constant velocity, power can be expressed as:

$$P = F \cdot v$$

where:

• $F$ is the force applied
• $v$ is the velocity of the object

The standard unit of power in the International System of Units (SI) is the watt (W), which is equivalent to one joule per second ($\text{J/s}$).
