Understanding Acceleration

Acceleration Formula

Acceleration is the rate of change of velocity with respect to time.

a = (v₁ - v₀) ÷ t

Where:

  • a = acceleration
  • v₁ = final velocity
  • v₀ = initial velocity
  • t = time interval

Types of Acceleration

  • Positive Acceleration: When an object speeds up
  • Negative Acceleration: When an object slows down (also called deceleration)
  • Zero Acceleration: When an object moves at constant velocity
  • Uniform Acceleration: When the rate of change of velocity is constant
  • Non-uniform Acceleration: When the rate of change of velocity varies

Common Acceleration Examples

Free Fall (Earth)
9.8 m/s²
Car (0-100 km/h)
~2.5 m/s²
Rocket Launch
~30 m/s²
Emergency Braking
~7 m/s²
Roller Coaster
~4 m/s²
Fighter Jet
~60 m/s²

Unit Conversions

Metric to Imperial

  • 1 m/s² = 3.28084 ft/s²
  • 1 m/s = 3.28084 ft/s
  • 1 m/s = 2.23694 mph

Imperial to Metric

  • 1 ft/s² = 0.3048 m/s²
  • 1 ft/s = 0.3048 m/s
  • 1 mph = 0.44704 m/s
