    Power Work
In summary, work is the transfer of energy from one object to another by applying force and causing it to move. It is calculated by multiplying the force applied by the distance over which it is applied. Power is the rate at which work is done or energy is transferred, and is typically measured in watts. Power and work are closely related, as power is the rate at which work is done, and they are directly proportional to each other, but inversely proportional to time.

If I lift an objct that weighs 1kg a distance of 1.5 meters in 2.5 seconds, what is my work and power done?

Can you show me how you did it?

I don't know how

Start off with the definition of Work done. How do you calculate it?
 
  • #3
w=fd

i got 14.7 for work

and

5.88 for power
 
  • #4
So you do know how. ;)

F=mg=1*9.81= #

W=Fd=#*1.5= ____ J

P=W/t and your answers seem to be correct so.
 

1. What is work?

Work is defined as the product of force and displacement. In simpler terms, it is the transfer of energy from one object to another by applying force and causing it to move.

2. How is work calculated?

Work is calculated by multiplying the magnitude of the force applied by the distance over which the force is applied. The formula for work is W = F x d, where W is work, F is force, and d is distance.

3. What is power?

Power is the rate at which work is done or energy is transferred. It is typically measured in watts (W) and is equal to the amount of work done divided by the time it takes to do the work.

4. How is power related to work?

Power and work are closely related, as power is the rate at which work is done. This means that the more work that is done in a given amount of time, the higher the power output will be.

5. How are work and power related to each other?

Work and power are related by the equation P = W/t, where P is power, W is work, and t is time. This equation shows that power is directly proportional to work and inversely proportional to time, meaning that as work increases, power also increases, but as time increases, power decreases.
