Worksheet 6: Friction Questions 1. This is true. You exert a backwards frictional force on the Earth, and by Newton’s 3 rd Law, experience a forward force on yourself, due to the Earth. 2. Since there’s no way to exert an horizontal force on the ice pond (and recieve the reaction force from the pond), there’s no way to walk to the shore. The only way to move is to throw something. In this way, the you give an object a forwards force, and you experience the backwards reaction force. The object will go one direction, while you will move in the opposite direction. 3. The frictional force on the plate is zero. Friction will only attempt to prevent the relative motion of two objects in contact. Since the waiter and the plate are traveling with the same velocity, with no acceleration, there is no need for friction to accelerate the plate. Problems 1. A block is pulled over a horizontal surface. (a) The forces are: Normal force fue to the ground, gravitational force, the force
