Activity 82 Analysis Questions

Activity 82 In Case You Missed It Braking distance: the time between when the brakes are applied and when the car actually stops. Friction: opposes the motion of an object; slows an object down. Increased friction allows cars to shorten their braking distance.

Work Formula

How much work is applied to an object with a mass of 15 kg and an acceleration of 14 m/s 2 over a distance of 0.5 m?

Activity 83: Coming to a Stop Please open your books to page E45.

Activity 83: Coming to a Stop What factors do you think affect whether you can stop quickly while driving on a road?

Activity 83: Coming to a Stop A driver of a car has control over two things: alertness and speed of the car. AlertnessCar Speed Can affect reaction distance and how far away the driver notices a hazard. The more alert a driver, the sooner a hazard is seen. Increased speed increases both reaction distance and braking distance.

Activity 83: Coming to a Stop Reaction Time: how long it takes someone to change their behavior based on their condition and the condition of their surroundings. Stopping Distance: distance travelled during reaction time plus how long it takes for the braking distance.

Activity 83: Coming to a Stop Procedure steps #1 and #2: use the charts in the OneNote Content Library. Step #3: show Miss Pyle your tables from #1 and #2 to get the graph paper!

Activity 83: Coming to a Stop Your friend says that when a car goes twice as fast, the braking distance doubles. Do you agree or disagree? Use evidence from this investigation to support your ideas! Nope, they are wrong! If the car is going twice as fast, the braking distance more than doubles. For example, the braking distance for 20 MPH on a dry road is 14 meters, but at 40 MPH it is 54 meters.
