/ I / the Phenomenon |
|
Forces have real impacts on the motion and interactions of objects in the Universe both large and small.
[CER] DISCUSSION QUESTION:
What would your life be like without the force of friction? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / INvestigate
1. Speed and collisions - investigate how vehicle speed affects the forces involved in a collision.
2. Measuring speed - investigate how can you measure the speed of a moving cart. 3. Investigating friction - investigate the force of friction on various sneaker and shoe designs. |

Forces and Motion: Basics Guide
|
Discover and describe how different strengths and directions of pushes affect 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.

EXPERT [+5 points]
Scientists need to know how the speed of an object impacts the forces involved during a collision in order to create driverless cars in the future. Plan an investigation to help them out.

/ v / Knowledge Check
Students wanted to compare the effects of different strengths on the motion of an object. The students set up a pulley to change the motion of the cart as it is pulled by a string attached to a weight. A motion detector calculates the changing speed of the cart as it moves. A graph of speed and time will give the acceleration of the cart on a computer.
