Explanation:

Task 4 - Potential and Kinetic Energy of First Car on Roller - Coaster

Step1: Determine greatest potential energy

The first car has the greatest potential energy when it reaches the top of the steepest hill on its track. This is because gravitational potential energy is given by $U = mgh$ (where $m$ is mass, $g$ is the acceleration due to gravity, and $h$ is height), and height $h$ is maximum at the top of the hill.

Step2: Determine greatest kinetic energy

The first car has the greatest kinetic energy when it is at the bottom of the steepest hill. Kinetic energy is $K=\frac{1}{2}mv^{2}$. As the car descends the hill, potential energy is converted into kinetic energy, and speed $v$ is maximum at the bottom of the hill.

Task 5 - Drawing and Labeling

Step1: Drawing the coaster

This requires visual - spatial skills. Observe the animation at the given website and draw a representation of the roller - coaster in the provided space, including hills, loops, etc.

Step2: Labeling potential energy points

Watch the animation and identify the three points where the height (and thus potential energy) is the greatest. Label these points with arrows.

Task 6 - Real - World Examples

Step1: Gravitational Potential Energy

Example A: A book on a high shelf has gravitational potential energy due to its height above the ground. Example B: A boulder at the top of a cliff has gravitational potential energy.

Step2: Elastic Potential Energy

Example A: A stretched rubber band has elastic potential energy. Example B: A compressed spring in a pogo - stick has elastic potential energy.

Step3: Kinetic Energy

Example A: A moving car has kinetic energy. Example B: A flying baseball has kinetic energy.

Task 7 - Venn Diagram

Step1: Elements in Kinetic Energy circle

Write characteristics and examples specific to kinetic energy, such as "associated with motion", "depends on mass and speed".

Step2: Elements in Potential Energy circle

Write characteristics and examples specific to potential energy, such as "stored energy", "gravitational and elastic types".

Step3: Overlap

Write elements that are common to both, such as "both are forms of mechanical energy", "can be converted from one to the other".

Answer:

Task 4:

• Greatest potential energy: At the top of the steepest hill.
• Greatest kinetic energy: At the bottom of the steepest hill.

Task 5: Draw the roller - coaster as per the animation and label the three points of greatest potential energy.
Task 6:

• Gravitational Potential Energy: Example A: Book on a high shelf; Example B: Boulder at the top of a cliff.
• Elastic Potential Energy: Example A: Stretched rubber band; Example B: Compressed spring in a pogo - stick.
• Kinetic Energy: Example A: Moving car; Example B: Flying baseball.

Task 7: Create a Venn diagram with appropriate elements in the kinetic, potential, and overlap sections as described above.
