The watt or joule per second is the unit of power in SI
The formula is:
1 W= 1 N.m = kg.m2/s2
Substituting the values given:
W=10.12/22
W=10/4=2.5
When a person lifts a bucket upward, the person exerts an upward force on the bucket, and the bucket exerts a downward force on the person. When a bucket is pushed along the ground, the person exerts a forward force on the bucket, and the bucket exerts an equal and opposite backward force on the person.
Yes, work is done when a person carries a bucket to some distance against gravity. Work is defined as force applied over a distance, so when the person lifts the bucket, they are exerting force over a vertical distance against gravity.

They lower a platform to the ground, where the wheelchair is placed, then it is slowly raised back up into the vehicle. Some lifts are designed for the person to be sitting on the wheelchair during, while others are strictly for the wheelchair itself.
The energy transformation that occurs when a person lifts a chair involves converting chemical energy from the food consumed into mechanical energy to move the muscles, which lifts the chair against the force of gravity.
There are several kinds of car lifts in operation today. Some of which are two post lifts, 4 post lifts, 4 post alignment lifts, inground lifts, mobile column lifts, short rise lifts, mid rise lifts and home garage lifts.
