To practice tactics box 10.1 calculating the work done by a constant force. to find the work done on an object by a force, begin with a visual overview and follow tactics box 10.1. recall that the work w done by a constant force f⃗ at an angle θ to the displacement d⃗ is w=fdcosθ. the vector magnitudes f and d are always positive, so the sign of w is determined entirely by the angle θ between the force and the displacement.

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
