Core Concepts in Physics 1 Final Exam Review
Kinematics
Kinematics deals with describing motion without considering its causes. Key concepts include:
- Displacement, velocity, and acceleration
- Equations of motion for constant acceleration
- Graphical analysis of position, velocity, and acceleration
- Relative motion
Sample problems to practice:
- Calculating the velocity of an object at a certain time
- Determining the displacement after a given time interval
- Analyzing motion graphs
Dynamics and Newton's Laws
Understanding forces is central to physics. Newton's three laws form the basis:
1. An object remains at rest or in uniform motion unless acted upon by a net force.
2. F = ma (Force equals mass times acceleration)
3. For every action, there is an equal and opposite reaction.
Important topics include:
- Frictional forces
- Tension, normal, and gravitational forces
- Free-body diagrams
- Applying Newton's laws to solve problems
Work, Energy, and Power
These concepts describe how energy is transferred and conserved.
- Work done by a force: W = F·d·cos(θ)
- Kinetic energy: KE = ½ mv²
- Potential energy (gravitational): PE = mgh
- Conservation of energy
- Power: P = work/time
Practice tips:
- Setting up energy conservation equations
- Calculating work done by different forces
- Analyzing energy transfer in systems
Momentum and Collisions
Momentum is a vector quantity: p = mv. Key principles include:
- Impulse-momentum theorem: J = Δp
- Conservation of momentum in isolated systems
- Types of collisions: elastic and inelastic
- Calculating final velocities
Sample problems:
- Finding velocities after collisions
- Analyzing explosions
- Calculating impulse during impacts
Rotational Motion
Rotational dynamics extend linear concepts to spinning objects:
- Angular displacement, velocity, and acceleration
- Moment of inertia (I)
- Torque (τ) and its relation to angular acceleration: τ = Iα
- Rotational kinetic energy: KE_rot = ½ Iω²
- Conservation of angular momentum
Key formulas to memorize:
- Torque: τ = r × F
- Angular acceleration: α = τ / I
Oscillations and Waves
Understanding periodic motion and wave phenomena:
- Simple harmonic motion (SHM)
- Characteristics of oscillations: amplitude, period, frequency
- Wave properties: wavelength, frequency, speed
- Doppler effect and wave interference
Practice problems:
- Calculating period and frequency of oscillators
