Never Calculate Work wrong again!
Work is the transfer of energy to or from an object that causes the object to move. Energy is required to do this so when you do work, you are just transferring energy from yourself to the object you are moving. In this video we will...

Power - What is Power and How Do I Calculate Power?
Power is the amount of work that is done in a given amount of time. You can also think about power as the rate that work is done. We can solve for power using the formula P=W/t where p is power in watts, W is work in J and t is time in...
