acceleration

• 1. Velocity=acceleration x time
  2. Acceleration= velocity/time
  3. Time= velocity x acceleration

  
• (final velocity)2 – (initial velocity)2 = 2 × acceleration × distance
• What is the acceleration of free fall?


  9.8 meters per second square
• Estimate the magnitudes of some everyday accelerations

  • Free Fall: Estimate that objects fall at about 10 m/s² due to gravity.
  • Braking Car: If a car stops in 5 seconds from 30 m/s, the deceleration is roughly 6 m/s².
  • Car Acceleration: If a car takes 10 seconds to reach 100 km/h from rest, the acceleration is approximately 2.78 m/s².
