This week we began to conduct research, demonstrations, and experiments in order to answer the Unit 3 key question, “How do forces affect motion?” This week we worked towards answering the unit question by investigating the activity key questions listed below. After conducting our activities of the day, we often have class consensus discussions in which a few students volunteer their individual answers to these questions. We then discuss our ideas and come up with a statement we can all agree upon. Some examples are provided below. They may come from either block.

Key Questions of the week:
How does a constant forward force affect motion?

Class Consensus: (Based on our observations in class.) A constant forward force acting on an object causes the object to speed up. (More to come on balanced forces and terminal velocity.)

How can a force arrow be used to represent a force?

Class Consensus: A force arrow can represent a force by having its length represent the strength of the force and the direction of the arrow represents the direction of the force.

What kind of motion does an object have if there are no interactions affecting the object’s motion?

Class Consensus: If there are no interactions affecting an object’s motion, it will maintain its speed and direction. Newton’s first law - An object at rest stays at rest, and an object in motion stays in motion with the same velocity unless acted upon by an unbalanced force.

How does a backward force affect motion?

In addition to some classroom demonstrations involving low friction cars propelled by fans, as well as blow dryers interacting with marbles, we checked out this video illustrating vector addition, in which mythbusters work to balance the opposing forces being applied to a soccer ball by the opposing forces of a vehicle and a cannon.

What is friction?

We analyzed the nitty gritty at the microscopic level.

Fun stuff!
