Power - What is Power and How Do I Calculate Power?

The video tutorial explains the concept of power, defined as the rate at which work is done. It introduces the formula P = W / T, where P is power in watts, W is work in joules, and T is time in seconds. The tutorial uses a triangle method to simplify solving for power, work, or time. Two examples are provided: one calculates power when work and time are known, and the other calculates work when power and time are given.

What is power in the context of physics?

• The total distance an object moves

• The speed at which an object travels

• The rate at which work is done

• The amount of energy stored in an object

Which formula is used to calculate power?

• P = F * d

• P = m * a

• P = W / T

• P = E / t

What does the triangle method help you determine?

• Whether to increase or decrease

• Whether to add or subtract

• Whether to multiply or divide

• Whether to use sine or cosine
