Furthering our understanding through obtaining information
Note to self: use this video to introduce energy as the key word to explore.
POTENTIAL & KINETIC ENERGY - METEOR IMPACT STUDY Continued
Vocabulary:
- Potential Energy: Stored Energy due to the objects mass & position (height)
- Kinetic Energy: Energy in motion due to the objects mass and speed.
Energy Simulations on Phet
- Objective:
- Run a few simulations and take note of the objects speed and position and how it relates to potential energy & kinetic energy.
- Next, draw a model and point out the following:
- Where does the object have the greatest speed?
- Where does the object have the greatest height?
- Where does the object have the greatest potential energy?
- Where does the object have the greatest kinetic energy?
- What is going on as the object is going up?
- What is going on as the object is going down?
- Can the object go higher than the original position? Why or why not?
- Observe what is happening with the total amount of energy.
Online Labs:
The Third Pendulum Lab: Link
- Click on the 3rd lab and do the following:
- Keep the gravity on earth & no friction
- Click and drag the mass to about 45-65 degrees
- Check the velocity option
- Check the Energy Graph
- Run the simulation & answer the questions above.
Skate Park 1: Link
- Be prepared to tell me how it all works. This includes the relationship with kinetic and potential energy relative to the objects height and speed, and the transformation in between
Meteorite Impact Online Calculator:
- Impact Calculator: Link
- Objective:
- Change a few factors and then run the simulator and see how kinetic energy plays a factor with the results.
