Key Takeaways
Lesson Description
Key Takeaways
• Position, displacement, distance, speed, velocity, and acceleration describe motion.
• Velocity is the rate of change of displacement.
• Acceleration is the rate of change of velocity.
• Motion graphs (position-time, velocity-time, acceleration-time) describe object motion.
• The slope of a position-time graph is velocity.
• The slope of a velocity-time graph is acceleration.
• The area under a velocity-time graph equals displacement.
Must Know Equations
v = Δx / Δt
a = Δv / Δt
v = v₀ + at
Δx = v₀t + ½at²
v² = v₀² + 2aΔx
