Newton’s First Law (Balanced Forces) Examples Example 1 Frictionless Incline Box Since the box has three interactions it has three forces acting upon it. Earth Rope
Newton’s First Law (Balanced Forces) Examples Example 1 Frictionless a. Draw a force diagram for the box. Remember, rotate the axis to make the motion one dimensional!
Example 1 Frictionless a. Draw a force diagram for the box.
Example 1 continued Frictionless b. Write an equation for the parallel forces and components. What force is needed to pull the box up the incline at constant velocity? But
Example 1 continued Frictionless c. Write the equation for the perpendicular forces and components. Calculate the normal force acting on the box. But
