5.6.3 Acceleration

• What is the definition of acceleration?

  Rate of change of velocity
• The formula for calculating acceleration is a = $\frac{\Delta v}{\Delta t}$
• What does $a$ represent in the acceleration formula?


  Acceleration
• If the change in velocity is positive, the acceleration is positive.
• The SI unit of acceleration is meters per second squared.
• A car accelerates from 10 m/s to 25 m/s in 5 seconds. What is the acceleration?

  3 m / s^{2}
• Match the term with its symbol:

  Acceleration ↔️ $a$

  Change in Velocity ↔️ $\Delta v$

  Change in Time ↔️ $\Delta t$

  $F =$$ma$
• The SI unit for acceleration is m / s^{2}.
• What is the SI unit of acceleration?

  $m / s^{2}$
• Acceleration is calculated using the formula a = $\frac{\Delta v}{\Delta t}$
• What does $\Delta t$ represent in the acceleration formula?


  Change in time
• Match the term with its description:

  Acceleration ↔️ Rate of change of velocity

  Change in Velocity ↔️ Final velocity minus initial velocity

  Change in Time ↔️ Duration of velocity change
• The SI unit of acceleration is meters per second.

  False
• A car accelerates from 10 m/s to 25 m/s in 5 seconds, resulting in an acceleration of 3 m / s^{2}.
• What is the formula for calculating acceleration?

  $a =$$\frac{\Delta v}{\Delta t}$
• $a$ represents the acceleration in the formula.
• How is the change in velocity calculated in the acceleration formula?

  $v_{f} - v_{i}$
• Acceleration is the rate of change of velocity
• The SI unit of acceleration is $m / s^{2}$
• What is the SI unit for acceleration?

  $m / s^{2}$
• Change in velocity is calculated as final velocity minus initial velocity.
• The change in time is measured in seconds
• What is the formula for calculating acceleration?

  $a =$$\frac{\Delta v}{\Delta t}$
• Positive acceleration occurs when an object's velocity increases over time.
• Negative acceleration is also known as deceleration or retardation.
• What happens to the direction of velocity during positive acceleration?

  Increases
• Negative acceleration has a negative sign.
• How is acceleration defined?

  Rate of change of velocity
• If the change in velocity is negative, the acceleration is negative.
• The SI unit of acceleration is meters per second squared.
• Acceleration is the rate of change of velocity
• The change in velocity is the difference between final and initial velocities
• Newton's Second Law relates force, mass, and acceleration.
• Acceleration is the rate at which an object's velocity changes over time

  $a =$$\frac{\Delta v}{\Delta t}$
• \Delta v represents the change in velocity.
• What does \Delta t represent in the acceleration formula?

  Change in time
• What is negative acceleration also known as?

  Deceleration
• The sign of the acceleration value is negative during deceleration.
