      C. Putting It All Together : Step by Step Solutions:

Let’s look at how to apply these strategies to different types of AP Physics 1 problems using the equation sheet.


  1. Kinematics Problems: Putting Motion Equations into Practice

Example: A car accelerates from 10 \, \text{m/s} to 30 \, \text{m/s} over 10 \, \text{s}. Find the acceleration and the distance travelled.


  • Identify knowns: v_0 = 10 \, \text{m/s}, v = 30 \, \text{m/s}, t = 10 \, \text{s}.
  • Use a = \frac{v - v_0}{t}:a = \frac{30 - 10}{10} = 2\text{m/s}^2
  • Use \Delta x = v_0 t + \frac{1}{2} a t^2:
    \Delta x = (10 \, \text{m/s})(10 \, \text{s}) + \frac{1}{2} (2 \, \text{m/s}^2)(10 \, \text{s})^2 = 100 \, \text{m} + 100 \, \text{m} = 200 \, \text{m}.


  1. Force and Dynamics Problems: Applying Newton’s Laws with Equations

Example: A 15 \, \text{kg} box is pushed with a 100 \, \text{N} force on a surface with a friction coefficient of 0.3. Find the acceleration of the box.


  •         Identify known: m = 15 \, \text{kg},F_{\text{push}} = 100 \, \text{N},\mu = 0.3.
  •         Calculate the frictional force: F_{\text{friction}} = \mu mg = 0.3 \times 15 \times 9.8 = 44.1 \, \text{N}.
  •         Determine the net force: \Sigma F = F_{\text{push}} - F_{\text{friction}} = 100 - 44.1 = 55.9  \text{N}.
  •         Use \Sigma F = ma: 55.9 = 15a.
  •         Solve for a: a = \frac{55.9}{15} \approx 3.73 \, \text{m/s}^2.


  1. Circular Motion and Rotational Motion Problems: Analysing Curved Paths

 Example: A 0.5 \, \text{kg} ball attached to a 1.5 \, \text{m} string is whirled in a horizontal circle at 4 \, \text{m/s}. Find the tension in the string.


  •  Identify knowns: m = 0.5 \, \text{kg}, r = 1.5 \, \text{m}, v = 4 \, \text{m/s}.
  • Use a_c = \frac{v^2}{r}: a_c = \frac{4^2}{1.5} = \frac{16}{1.5} \approx 10.67 \, \text{m/s}^2.
  •  Determine the tension using T = m a_c: T = 0.5 \times 10.67 \approx 5.34 \, \text{N}.


  1. Simple Harmonic Motion Problems: Solving for Oscillations

Example: A mass-spring system oscillates with a spring constant k = 200 \, \text{N/m} and a mass m = 2 \, \text{kg}. Find the period of oscillation.


  •         Identify knowns: k = 200 \, \text{N/m}, m = 2 \, \text{kg}.
  •         Use T = 2\pi \sqrt{\frac{m}{k}}: T = 2\pi \sqrt{\frac{2}{200}} = 2\pi \sqrt{0.01} = 2\pi \times 0.1 = 0.2\pi \approx 0.63 \, \text{s}.


D. Double-Checking Your Work: Making Sure Your Answers Are Right

After solving the problem, it’s crucial to verify your answer:

  • Check units: Ensure that your final answer has the correct units.
  • Recalculate key steps: Go through your calculations again to spot any arithmetic errors.
  • Assess reasonableness: Consider whether the answer makes sense physically (e.g., no negative distances or impossible speeds).
  • Cross-reference: Compare your answer with related principles or equations to ensure consistency.
