Astronomy 100 HW #3 1) Momentum is the result of an object’s mass times it’s velocity. If a force is greater than the momentum of a given object (A), then object “A” will move in the opposite direction. If the force is less than the momentum of object “A” will continue in the same direction. A net force is the force that an object responds to, and that net force equals the change in an objects momentum after a force hits the object. 2) This makes sense and relates to Newton’s first law. When the astronaut steps out of the station gravity is pulling her away, and the force of the gravity of space will continually pull her, until an outside force (the tension in the tether or the fire thrusters) pulls her back in the direction of the space station. In other words she will continue in motion until she is acted upon by the outside force of the tether or thrusters. 3) Newton’s second law, stating Force equals mass times acceleration, best explains why it is so much harder to throw a bowling ball than a baseball.
