A gardener pushes a wheelbarrow along a level path. The horizontal force from the gardener is 30 N and the wheelbarrow moves 2.0 m in the direction of this force. The wheelbarrow then stops because of friction.
State the relationship between the work done by a force and the energy transferred by the force.
Calculate the work done by the gardener's force.
Use E=F×dE = F \times dE=F×d.
State the energy store that increases as the wheelbarrow stops because of friction.
