  1. Remember that Force is also a vector - it has to include direction in the answer.
  2. If I send a ball rolling across the floor, it will continue at the same speed and direction unless it encounters another force. What forces might it encounter
  3. If I send a ball rolling across the floor, it will continue at the same speed and direction unless it encounters another force. What forces might it encounter
