11-24

On monday November 24 physics class took place. The class started without a daily question unusually, but students were required to pick up three handouts(Unit 5A Newton’s 3rd law, a collisions demo paper, and the reading guide for unit 5A). No assignments were handed in due to now homework from a previous test day. The agenda for class was the following..Pass back reading guides and tests from unit 4 followed by a review of that test on unit 4. All questions were answered with confidence by Mr. Manning. Then class switched over to demonstrations of collisions. This demonstration was done using force scales mounted to small cart-like vehicles. Manning smashed the carts together while showing the forces received by the carts on the smartboard. Carts were altered to see how it affects the data...Weight was added to the cars, they moved at different velocities before the collision, they were a head on or rear end crash, and sandpaper was also used to see how friction plays a role. The students were given time to discuss and come up with predictions for the given scenarios. Students were then called on to give their predictions while Mr. Manning had every one fooled when they chose new answers. It all ended up with the same final data of each cart receiving an equal amount of force. The forces were displayed as negative but this was only due to the way in which the force scales were used. No homework assignments were given although a reminder to get started on the reading guide early was mentioned. Then stories involving car accidents were discussed to the relation of exerted forces in an accident.
