100: Define acceleration. 


(A change in an object’s speed or direction over time)

100

100: What does a positive slope on a speed-time graph represent? 


(Speeding up/positive acceleration)

100

  • 100: In the formula a = (vf – vi) ÷ t, what does vf stand for? 


Final Velocity

100

  • 100: Give an example where acceleration is important for safety.


 (Braking in a car)

100

  • 100: Name one way velocity can change without speed changing.

(Direction changes)

200

200: Name three ways an object can accelerate. 


(Speeding up, slowing down, changing direction)

200

  • 100: What is positive acceleration? 


(Speeding up)

200

  • 200: In the formula a = (vf – vi) ÷ t, what does vi stand for? 


Initial Velocity

200

  • 200: Give an example where acceleration is important for fun.

200

  • 200: True or False: A parked car has acceleration.

False

300

300: What is the unit for acceleration in the SI system? 


(m/s²)

300

  • 200: What is negative acceleration?


 (Slowing down)

300

  • 300: What three things must you know to calculate acceleration?

(Initial velocity, final velocity, time)

300

  • 300: Give an example of a sport where acceleration matters.


  • (Sprinter at start of race)

300

  • 300: Why is direction part of acceleration? 


(Because velocity includes direction)

400

400

  • 400: A bicyclist speeds up from 2 m/s to 8 m/s in 3 seconds. What is the acceleration? 


(2.0 m/s²)

400

  • 400: Why is acceleration important for designing roller coasters?

  •  (It determines safety and excitement levels)

400

  • 400: Explain why acceleration can be negative. 


(Because speed decreases)

500

500: True or False: Acceleration only happens when speed increases. 


(False)

500

  • 400: Give an example of negative acceleration in everyday life. 

(Car braking at a red light)

500

  • 500: A car slows down from 20 m/s to 10 m/s in 5 seconds. What is the acceleration? 

(-2.0 m/s²)

500

  • 500: How can engineers use acceleration data? 

(To design safer, more efficient vehicles)

500

  • 500: How is acceleration different from velocity? 

(Acceleration is change of velocity over time; velocity is speed with direction)
