In summary, the formula for calculating power is P = W/t, work is calculated by W = Fd, the unit of measurement for power is watt (W), both power and work can have negative values, and power is related to energy as it is the rate at which energy is transferred or converted. The unit of measurement for energy is joule (J).

Homework Statement


What is the power being exerted by a force of 1000. N on a car traveling at 30. m/s? (Assume that force and speed are in the same direction, and treat all numbers as positive.)

Homework Equations


Power = J/s
Work =F*d

I got it. Since a Joule is a N*m, and Power is a N*m/s; I just multiple the 1000N by 3m/s to get the power. Thanks brain!
 

1. What is the formula for calculating power?

The formula for calculating power is P = W/t, where P is power, W is work, and t is time.

2. How do you calculate work?

Work is calculated by multiplying the force applied to an object by the distance it moves in the direction of the force. The formula is W = Fd, where W is work, F is force, and d is distance.

3. What is the unit of measurement for power?

The unit of measurement for power is watt (W). It is equivalent to one joule per second (J/s).

4. Can power and work have negative values?

Yes, both power and work can have negative values. This indicates that the force and the direction of movement are in opposite directions.

5. How does power relate to energy?

Power is the rate at which energy is transferred or converted. This means that the higher the power, the faster energy is being used or transferred. The unit of measurement for energy is joule (J).
