For every action there is an equal and opposite reaction.
[CER] DISCUSSION QUESTION:
Are design solutions for car accidents good enough? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / Investigate
1. LEGO collisions - design solutions to save the eggs from catastrophic "eggcidents?!"
2. Rocket Science - design solutions to launch a rocket to a desired target. 3. Spring Scale Scavenger Hunt- investigate Newton's 3rd law using spring scales. 4. Balloon Racers - investigate Newton's 3rd law using balloon racers. |

During this lesson you will learn more about how to how you can predict an object’s motion, changes in motion, and stability.
✎Notes:
- For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first but in the opposite direction (Newton’s third law).
- The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change.
- The greater the mass of the object, the greater the force needed to achieve the same change in motion.
- For any given object, a larger force causes a larger change in motion.
- Forces on an object can also change its shape or orientation.
- All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared.

Draw and explain a solution to minimize injuries from collisions between two cars using Newton's Third Law of Motion. ADVANCED [+4 points]
Using the graph showing how the velocity of a parachutist changes as evidence - describe how effective a parachute is in solving the problem of a person colliding with Earth. In your description use your knowledge of Newton's third law to determine how well this design solution meets the criteria and constraints for solving this problem for a parachutist. |

/ V / Knowledge Check
Meteoroids are small, solid particles being larger than an atom or molecule but smaller than an asteroid. Meteoroids are generated mainly from collisions between asteroids and the decay of comets.
During a meteor shower in 1993, an impact seemed to have led the Olympus 1 satellite to spin out of control. Efforts to regain control used up most of the spacecraft's fuel, leaving just enough to send it into a "graveyard" orbit. This got the space community involved in preventing impact damage between meteors and space vehicles. |
|
Satellites today are not defenseless. One current solution is to monitor when more intense meteor showers are expected, so satellites can orientate their solar panels edge-on to incoming meteors to minimize the chances of of a collision.
