Topic 5 Lesson 2 Study Guide

This is from the Topic 5 Lesson 2 Nearpod and textbook p. 229: A wagon with a large child would have more kinetic energy than a wagon with a small dog if they are both moving at the same speed. How do we know this?

• KE depends on mass and the dog has more mass
• KE depends on mass and the child has more mass
• They are going at the same speed so they have the same KE
• You cannot determine KE from this information

This is from the Topic 5 Lesson 2 Nearpod and textbook p. 232: What pulls on objects with gravitational potential energy?

• elastic potential energy
• kinetic energy
• gravity
• mass

This is from the Topic 5 Lesson 2 Nearpod and textbook p. 232: What two factors affect potential energy?

• an object's height
• a object's mass/weight
• an object's speed
• an object's velocity

This is from the Topic 5 Lesson 2 Vocab and Notes: What is the unit of measure for KE?

• watts
• meters
• seconds
• Joules

This is from the Topic 5 Lesson 2 Interactivity: Racing for Kinetic Energy Based on the data in the table, select ALL true answers.

• The graph of mass versus kinetic energy will be a straight line
• The graph of mass versus kinetic energy will not be a straight line
• As mass increases, KE increases
• As mass increases KE decreases

This is from the Interactivity: This is from the Topic 5 Lesson 2 Interactivity: Racing for Kinetic Energy Based on the data in the graph, what is the kinetic energy of a 5-kg car?

• 3 J
• 2.5 J
• 1.5 J
• 1 J

This is from the Topic 5 Lesson 2 Nearpod and textbook p. 231.

• potential energy
• power
• kinetic energy
• elastic potential energy

This is from the Topic 5 Lesson 2 Interactivity: Roller Coasters and Potential Energy. Which letters represent the LOWEST potential energy? Select all that apply.

• C
• G
• A
• B
• D

This is from the Topic 5 Lesson 2 Interactivity: Roller Coasters and Potential Energy. The Twister and Runaway Train are two coasters at the same amusement park. Both coasters start at the same height. The coaster for the Twister is twice the mass of the coaster for the Runaway Train. Which roller coaster has greater gravitational potential energy at the start of the ride?

• The Runaway Train
• Both coasters start with the same amount of potential energy.
• The Twister
• You cannot tell from this information.
