Good.
Let me know if there's anything you need me to explain.
For a given field direction and strength, object direction and object mass, what difference does the initial speed of the object make in the velocity change and the direction change? Answer: It appears that the initial velocity of the object is effected by the mass and the direction of the force
• For a given field direction and strength, object direction and speed, what difference does the object's mass make in the changes in object velocity and direction?
Answer: The greater the mass the less resistance the mass seems to have going through the force field. The velocity is accelerated either positive or negative depending on the direction of the field
• What does a repelling field whose direction is nearly parallel to the object's initial velocity tend to do to the path of the object in the case where the object has a large mass, as opposed to the case where the object has a small mass?
Answer: The smaller mass will increase in velocity much faster than a larger mass
• If the field is perpendicular to the path of the object, and if the object has large mass and velocity so that its direction of motion remains pretty much perpendicular to the path, will the speed of the object or its direction change more?
Answer: The smaller mass will be deflected almost immediately. The larger mass will flow through the force field depending upon the intensity of the force field and loose velocity accordingly
• If the field is parallel to the object's path and the attraction factor is 1, then will the field do positive or negative work on the object, and will the speed of the object increase or decrease? The Answer: force field will do positive work and the velocity will increase
• If the field is parallel to the object's path and the attraction factor is -1, then will the field do positive or negative work on the object, and will the speed of the object increase or decrease?
Answer: The field will do negative work and the velocity will decrease
