To practice tactics box 9.1 calculating the work done by a constant force. recall that the work w done by a constant force f⃗ at an angle θ to the displacement δr⃗ is w=f⃗ ⋅ δr⃗ =fδrcosθ. the vector magnitudes f and δr are always positive, so the sign of w is determined entirely by the angle θ between the force and the displacement.
