2.3. Acceleration

Try these first

1. 1.

   Define acceleration in your own words.

   Hint

   Think about how speed changes over time.

2. 2.

   What are the two components of acceleration?

   Hint

   Consider how speed change and direction are related.

3. 3.

   What is acceleration?

   Hint

   Remember it's about velocity change.

4. 4.

   True or False: Centripetal acceleration increases speed.

   • True
   • False

   Hint

   Focus on how it affects motion direction.

5. 5.

   A car travels around a curve of radius 50 meters with a speed of 20 m/s. What is the centripetal acceleration of the car?

   Hint

   Identify the radius and speed to apply the formula correctly.

6. 6.

   Explain how the Coriolis effect can alter the motion of a blade on a rotating lawn mower and derive the effect if the blade moves outward at 5 m/s with an angular speed of 40 rad/s.

   Hint

   Consider how rotational speed influences outward motion.
