Major Topics in AP Physics C: Mechanics
There are seven major topics in AP Physics C: Mechanics:
- Kinematics
- Newton’s Laws of Motion
- Work, Energy, and Power
- Momentum
- Rotational Motion and Dynamics
- Gravitation
- Oscillations and Simple Harmonic Motion
Let’s dive into these major topics:
1. Kinematics:
Kinematics is the study of motion without considering the forces that cause it. Key concepts include velocity, acceleration, and displacement in one and two dimensions.
$$🔹 v=v_0+a t$$
$$🔹 x=x_0+v_0 t+\frac{1}{2} a t^2$$
$$🔹 v^2=v_0^2+2 a\left(x-x_0\right)$$
$$🔹 a=\frac{d v}{d t}, v=\frac{d x}{d t}$$
2. Newton’s Laws of Motion:
Newton’s Laws explain the relationship between force and motion and form the foundation for understanding dynamics and object interactions.
🔹 Second Law: ∑𝐹⃗ = 𝑚𝑎⃗
🔹 Friction: 𝑓ₛ ≤ 𝜇ₛ𝑁, 𝑓ₖ = 𝜇ₖ𝑁
3. Work, Energy, and Power:
Students learn how forces perform work, the conservation of energy, and the rate of energy usage.
🔹 Work: 𝑊 = ∫𝐹⃗ ⋅ 𝑑𝑠⃗
🔹 Kinetic Energy: 𝐾𝐸 = ½𝑚𝑣²
🔹 Work-Energy Theorem: 𝑊 = Δ𝐾𝐸
🔹 Potential Energy (Gravitational): 𝑈𝑔 = 𝑚𝑔ℎ
4. Momentum:
The topic momentum is the study of motion in terms of momentum and impulses. It works with the application in collisions and conservation laws.
$$🔹Linear Momentum: \vec{p}=m \vec{v}$$
$$🔹Impulse: \vec{J}=\Delta \vec{p}=\int \vec{F} d t$$
$$🔹Conservation Of Momentum: \sum \vec{p}_i=\sum \vec{p}_f$$
5. Rotational Motion:
In simple words rotational motion can be explained as the motion of an object around the circular path or a central line in a fixed orbit. The orbit might be clockwise or anticlockwise.
$$🔹 \omega=\omega_0+\alpha t$$
$$🔹\theta=\theta_0+\omega_0 t+\frac{1}{2} \alpha t^2$$
$$🔹\omega^2=\omega_0^2+2 \alpha\left(\theta-\theta_0\right)$$
Rotational Inertia (Moment of Inertia)
$$🔹I=\sum m_i r_i^2$$
$$Torque: \tau=r F \sin \theta=I \alpha$$
$$Rotational Kinetic Energy: K E_{\mathrm{rot}}=\frac{1}{2} I \omega^2$$
$$Angular Momentum: \vec{L}=I \vec{\omega}, \tau=\frac{d \vec{L}}{d t}$$
6. Gravitation:
In this topic students learn about Newton’s law of gravitation, orbital mechanics, and potential energy of objects under gravitational force influence.
$$Newton’s Law Of Gravitation: F=G \frac{m_1 m_2}{r^2}$$
$$Gravitational Potential Energy: U=-G \frac{m_1 m_2}{r}$$
$$Orbital Velocity: v=\sqrt{\frac{G M}{r}}$$
$$Period Of Orbit: T^2=\frac{4 \pi^2 r^3}{G M}$$
7. Simple Harmonic Motion (SHM):
In this topic students will learn about the Oscillatory system that include pendulums, springs, periodic motion, restoring forces and energy conversions.
$$Period Of Spring: T=2 \pi \sqrt{\frac{m}{k}}$$
$$Period Of Pendulum: T=2 \pi \sqrt{\frac{L}{g}}$$
