Answer
Explanation:
Task 4
Step1: Determine greatest potential energy
Potential energy ($PE = mgh$) is greatest at highest point. So, the first - car has the greatest potential energy when it reaches the top of the steepest hill on its track.
Step2: Determine greatest kinetic energy
Kinetic energy ($KE=\frac{1}{2}mv^{2}$) is greatest at lowest point (where speed is highest). So, the first - car has the greatest kinetic energy when it is at the bottom of the steepest hill.
Task 5
Step1: Draw the coaster
You need to visit the provided website, observe the animation, and draw the roller - coaster in the given space. Pay attention to the shape of the track, the cars, and any notable features.
Step2: Label points of greatest potential energy
On the animation, the points of greatest potential energy are the highest points on the track. Use arrows to label these 3 highest points.
Task 6
Step1: Gravitational potential energy examples
A book on a high shelf has gravitational potential energy. Another example is a boulder at the top of a cliff.
Step2: Elastic potential energy examples
A stretched rubber band has elastic potential energy. A compressed spring in a pogo - stick is also an example.
Step3: Kinetic energy examples
A moving car has kinetic energy. A running person also has kinetic energy.
Task 7
Step1: Fill in the Venn diagram
In the "kinetic" circle, write characteristics such as "associated with motion", "depends on mass and speed ($KE = \frac{1}{2}mv^{2}$)". In the "potential" circle, write characteristics such as "stored energy", "gravitational ($PE = mgh$) or elastic". In the overlapping region, you could write "both are forms of mechanical energy".
Answer:
Task 4
The first car has the greatest potential energy at the top of the steepest hill and the greatest kinetic energy at the bottom of the steepest hill.
Task 5
Draw the coaster as seen in the animation and label the 3 highest points (where potential energy is greatest) with arrows.
Task 6
Gravitational Potential Energy: Example A - A book on a high shelf; Example B - A boulder at the top of a cliff. Elastic Potential Energy: Example A - A stretched rubber band; Example B - A compressed spring in a pogo - stick. Kinetic Energy: Example A - A moving car; Example B - A running person.
Task 7
In the "kinetic" circle: Associated with motion, depends on mass and speed ($KE=\frac{1}{2}mv^{2}$). In the "potential" circle: Stored energy, gravitational ($PE = mgh$) or elastic. In the overlapping region: Both are forms of mechanical energy.
