- Explain... 5. When you increase the mass of an object (while keeping the applied force the same) what happens to the rate of acceleration? Explain why this occurs using your understanding of Inertia (an object’s resistance to a change in motion). 6. When you apply a constant force to an object does the object move at a constant velocity or does its velocity increase? Explain why this occurs using your understanding of acceleration/force (gravity). 7. When you increase the applied force, what happens to the acceleration of the object? 8. As the mass increases, what happens to the amount of force needed to begin moving the object? Explain. 9. Do you need to continue applying force on an object to keep it moving?

- 3. Here is a problem that beautifully illustrates why we want this new approach. Problem: A mass of 3 kg is placed on a 600 that has a coefficient of 0.2. (Since the mass will be moving this is kinetic friction...) What is the resulting acceleration of the mass? The mass will then travel down the incline for 0.5 m until it reaches the bottom of the incline. How fast will the mass be traveling at the bottom of the incline? The mass will then slide across the floor (which is level). How far will it slide before coming to rest?1.
