|
Forces change the speed, direction, and shape of objects in predictable ways.
According to the National Highway Traffic Safety Administration, 392 crashes involving a vehicle equipped with Level 2 advanced driver assistance systems were reported in 2022. Level 2 refers to vehicles that control steering, acceleration, and deceleration. In the U.S. 42,795 people died in motor vehicle traffic crashes in 2022. Drinking and driving kills approximately 28 people a day in the U.S. — about one person every 52 minutes — That is more than 10,000 lives lost each year to drunk driving alone.
[CER] DISCUSSION QUESTION:
Do you think the design solutions for driverless cars today work as intended to change the speed and direction of cars? Agree or disagree? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / INvestigate
1. Braking distance - investigate how can friction lower the risk of getting into an accident.
2. Stopping on a dime - how can you design a basketball court so that players don’t run into band members and other spectators near the court lines? 3. LEGO marble maze - create a maze using LEGOs to have a marble move a certain distance, follow a particular path, and knock down other objects at the other end. |
Discover and describe how the force of friction affects the motion of the skateboard in this simulation.

/ Iii / Level Up!
During this lesson you will learn more about how you can predict an object’s motion, changes in motion, and stability.
✎Notes:
- Objects pull or push each other when they collide or are connected.
- Pushes and pulls can have different strengths and directions.
- Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it.
- An object sliding on a surface or sitting on a slope experiences a pull due to friction on the object due to the surface that opposes the object’s motion.
