  1. Solving Newton’s Second Law Problems

  2. Identify the physical properties involved and sketch • Use arrows to represent all forces acted upon • Label your forces appropriately First Step

  3. Determine what is needed to be found and what is given: Make a list of what is given and what is unknown • This is critical because Newton’s Second Law involves net external forces Step 2

  4. Putting data into the equation • Before you write net force equations, it is critical to determine whether the system is accelerating in a particular direction. If the acceleration is zero in a particular direction, then the net force is zero in that direction. Similarly, if the acceleration is nonzero in a particular direction, then the net force is described by the equation Step 3

  5. Fnet = ma • For example if the system is accelerating in the horizontal direction, bit it is not accelerating in the vertical direction, then you will have the following conclusions: • Fnetx = ma • Fnety = 0

  6. Always check to see if the solution is reasonable Step 4
