Science

We are investigating the relationships between force, mass, and acceleration.  Students are writing analyses and explanations of everyday scenarios in terms of forces and energy: type of interaction, whether or not the forces are balanced or unbalanced, if they are unbalanced, if it is in the direction of motion, the direction opposite of the object’s motion, or neither, and how all these factors affect the speed and/or direction of the object.    

Dinner Conversation Prompts:

  • What is given to an object during an interaction and stays with the object after the interaction is over?

    • What happens to a low friction car’s motion when there is a constant push on the car? There is an increase in speed during contact, as long as the force in the direction of motion is stronger than the forces opposite the direction of motion.

    • What happens to a low friction car’s motion when there is a quick push on the car? Barring any opposing forces like friction or drag, there is an increase in speed during contact, and then a constant speed after the interaction ends.

  • What can you say about the force being exerted on the low friction car while the car was speeding up? It was being acted upon by an unbalanced force in the direction of motion.

  • What can you say about the force being exerted on the low friction car while the car was slowing down? It was being acted upon by an unbalanced force opposite to the direction of motion (a backwards force).

  • What can you say about the force being exerted on the low friction car while the car had a constant speed? There were no unbalanced forces affecting the motion of the object.

  • Is there always a force exerted on an object in the direction of motion, to keep it moving? No.  A moving object does have motion energy that was transferred to it by a force (a push or a pull) at one time.

  • Colorado University offers a number of great science simulations for the public!  We used this one on Forces and Motion this week:  https://phet.colorado.edu/en/simulation/legacy/forces-and-motion

  • Another video we watched this week is Physics - What is Force? - Part 1:  https://www.youtube.com/watch?v=B6mi1-YoRT4

 

May the force be with you,

Carrie and India
