Lesson 3: Accelerated Motion

Lesson 3: Accelerated Motion

NOTE: The slides in these notes don't let you write or draw on them. For any prompt given in the notes, you will answer them on the following slide.. Answer the prompts in your notes before moving to the next slide.

Today's Objectives: I can...

• Define Acceleration

• Calculate acceleration and the distance moved by a falling object

• Identify graphs of accelerated motion

Draw these in your notes. You can use the video on the last slide to help with your example.

Remember: an object that is speeding up will have a distance v. time graph that starts flat then gets steeper.

Distance v. time graphs for objects slowing down start steep and end flat.

Multiple Select

Which of these shows an INCREASING speed? (Pick TWO; pay close attention to the y-axis to see what you're measuring.)

Multiple Select

Which of these shows a DECREASING speed? (Pick TWO; pay close attention to the y-axis to see what you're measuring.)

Multiple Choice

An object free falls for 14 seconds. How far does it fall?

• 980 m

• 98 m

• 9.8 m

• .98 m

You will answer on the next slide.

Multiple Choice

Which part of the diagram shows an acceleration?

Multiple Choice

An object goes from 0 m/s to 6 m/s over a period of 2 seconds. What is the acceleration of the object?

• 3 m/s

• 1 m/s

• 2 m/s²

• 3 m/s²

• 6 m/s²

On a scale of 1-5, how do you feel about our first objective: "I can define acceleration"

• 1 -- I have no idea how to do this

• 2 - I'm struggling and can use a little help

• 3 -- I might need more practice examples to try on my own

• 4 -- I understand

• 5 -- I got it and I can teach it to others
