Warmup

An object has 50 joules of potential energy. It is 20 meters off of the ground. How much mass does it have?

An object has 9 joules of potential energy. It is 37 meters off of the ground. How much mass does it have?

How much potential energy does a 45 kg mass have if it is 97 meters off of the ground?

Samantha and Mike are standing next to each other, facing a tall, concrete block wall. Samantha throws a tennis ball at the wall. The ball bounces off of the wall, and Mike catches it.

Does the ball have more energy, the same amount of energy, or less energy when Mike catches the ball as it did when Samantha threw it?

Why do you think so?

If the ball gained or lost energy, explain where the energy came from and where it went.

Use the same spring constant for each trial

Graph the values you found in the previous question.

We have released a new and improved Graphing question type! Students will no longer be able to answer this question.

How does the graph for the previous question compare to your graph from yesterday's lab?

https://goformative.com/formatives/61f15c6ca5cfa63b89357b07 (Question #21)

Add a screenshot of yesterday's graph here for comparison.

If your graph doesn't look like the theoretical graph above, what reasons could account for the differences?

(In other words, the graph of results from your experiment should be very similar. If it wasn't, what reasons can you come up with to explain why your experiment did not produce the ideal results?)

Compressing the spring vs. stretching the spring
Stretch and compress the spring by the same displacement.

Is the amount of elastic potential energy affected differently by compression than by stretching?

Explain why using the elastic potential energy formula.

What is elastic potential energy?

What is one way you can increase the elastic potential energy of an object?

What is a second way to increase elastic potential energy?

Which of the 2 ways has a greater impact on the Potential Energy?
