Scalars and Vectors
Scalars have magnitude only (speed, distance). Vectors have magnitude and direction (velocity, displacement, acceleration). Graphical vector addition uses head-to-tail method.
Displacement and Velocity
Displacement is change in position with direction. Average velocity = Δx/Δt. Instantaneous velocity is velocity at one moment. Speed is magnitude of velocity without direction.
Acceleration
Acceleration is change in velocity over time: a = Δv/Δt. Constant acceleration produces linear v-t graphs. Negative acceleration (deceleration) slows motion in the positive direction.
Kinematic Equations
For constant acceleration: v = v₀ + at, x = x₀ + v₀t + ½at², v² = v₀² + 2aΔx. Free fall near Earth uses a ≈ 9.8 m/s² downward. Choose the equation that includes known and unknown variables.
FAQ
- Are calculus derivatives required?
- No. This pack uses algebra-based kinematics from introductory high school physics.
- Which units are used?
- SI units: meters, seconds, m/s, and m/s² appear throughout.
