Newton's Law Assesment

1. What are the relationships between forces and motion? 

The relationship between forces and motion is that net force is required to accelerate an object or change the motion of an object.  F=MA. F=Force. M=Mass. A=Acceleration.  Force is needed to create motion.  Newton's first law, the law of inertia, says that an object at rest will stay at rest unless there is some kind of force put on it.  So no object can move unless there is a force, and that's the relationship between force and motion, because when an object is moving, that's the motion, only because of the force.

2. What are the variables that affect motion and force?

The variables that affect motion and force is mass and acceleration.  When you multiply the mass of an object by the acceleration, that's what creates the force.  Then with the force, that's how you create the motion.  An objects' motion if affected by the acceleration and speed, along with the forces that are involved.

3. How does Newton’s three laws describe the motion of a moving 
object? 

Newton's three laws describe the motion of a moving object because they all involve force.  His first law talks about how an object in motion will stay in motion unless an outside force interferes with it.  That talks about the object and its motion.  His second law talks about the direction the object in motion will move.  His third law talks about that when we leave an object, the object will go in the opposite direction, talking about that for every action, there is an equal and opposite reaction of the object in motion.

4. How does gravity impact objects?

The greater the mass, the greater the gravitational pull.  Mass is attracted to anything with a mass, and it's a force at a distance.
