Acceleration

• What is acceleration?

  How quickly you're speeding up
• How is acceleration defined in terms of velocity?

  It is the rate at which velocity changes over time
• What does the symbol 'a' represent in acceleration?

  Change in velocity
• What is deceleration?

  Negative acceleration, or slowing down
• What is uniform acceleration?

  • Constant acceleration
  • Acceleration due to gravity is uniform
  • Approximate value: $9.8 \text{ m/s}^2$
• What is the approximate value of acceleration due to gravity?

  9.8 m/s²
• What is the equation relating final velocity, initial velocity, acceleration, and distance?

  • Equation: $v^2 - u^2 =$$2as$
  • Where:
  • $v$ = final velocity (m/s)
  • $u$ = initial velocity (m/s)
  • $a$ = acceleration
  • $s$ = distance
• What does 's' represent in the equation $v^2 - u^2 =$$2as$?


  Distance
• What do 'v' and 'u' represent in the equation $v^2 - u^2 =$$2as$?


  Final and initial velocity
