Simulations with Pressure and Temperature
This will be used in conjunction with the handout given to you today. Please click on the link below to start the first simulation:
For the next simulation, click on this link:
§ Showed students exemplar car, explain they will have 3 types of balsa sticks to use.
§ go over how to crush sticks.
§ Show video of car rolling down. Use frames to find time. Go over average speed graphs.
Prelude: Free body diagram
Objective: a force requires a change in velocity or acceleration.
Notes on work:
Work= force* distance
Work is the change in energy of something.
Work = change in kinetic energy.
Kinetic energy: Energy of motion. Equation = 1/2mv2
Potential energy: energy of position
PE = mgh
Potential energy: a bow, an object elevated. Something that has a force acting on it but no work.
Introduce lab. Students will drop balls first and then measure the mass of their ball. 3 balls per group if possible. Two timers per group if possible.
