Work Done in Lifting a Barbell

Calculating Work Done in Lifting a Barbell

Work done on the barbell:

To calculate the work done when a weightlifter lifts a barbell, we need to know the force applied and the distance it is lifted. In this case, a very strong athlete can lift a 350 N barbell a distance of 2 meters from the ground.

Formula: W = F × d

Where:

W = Work (Joule or Nm)

F = Force (Newton)

d = Distance (meters)

Given:

Force (F) = 350 N

Distance (d) = 2 meters

Calculation:

W = F × d

W = 350 N x 2 m

W = 700 Joule

Therefore, the work done on the barbell by the weightlifter is 700 Joules.
