Question

a gardener has to apply more force to start the lawn mower and to keep it in motion why​

Answer 1

HI!!

Explanation:

its happens because

when he is starting the LAWN MOWER he has to overcome the static friction which opposes the motion of the lawn mower.

but when he is pulling the moving law mower he has to overcome dynamic/kinetic friction.

since static friction is more than dynamic/kinetic friction, he has to pull harder during the start.
