Question

RAVI IS SWIMMING IN THE POOL. STATE OUT WHETHER YES OR NOT WORK DONE IN THE LIGHT OF YOUR UNDERSTANDING OF THE TERM WORK, JUSTIFY YOUR ANSWER​

Answer 1

Answer:

Work is done because the displacement of swimmer takes place and a force is applied.

Answer 2

Yes work is done while swimming in the pool.

• Work done is "product of force and displacement in direction of force." It is mathematically represented as W = F*s.
• During swimming in the pool, which contains standing water, movement of arms and legs pushes the water backwards.
• The water in turn pushes the person forward, as per Newton's third law of motion.
• Thus force acts as well as displacement takes place. Hence, work is done while Ravi swims in the pool.
