/ I / the Phenomenon |
|
The motion of an object depends on the different strengths and direction of forces.
[CER] DISCUSSION QUESTION:
Can fair investigations be done to learn about forces? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / INvestigate
1. Investigating friction - investigate the force of friction on various sneaker and shoe designs.
2. Pendulum Power - investigate how the motion of an object depends on the strength of a force. |
/ Iii / Level Up!
During this lesson you will learn more about the underlying forces that explain the variety of interactions we observed between objects.
✎Notes:
- When objects touch or collide, they push on one another and can change motion or shape.

ACCOMPLISHED [+3 points]
Students conducted an investigation to compare the effects of different strengths and directions of pushes and pulls on the motion of a person stopping a rolling ball three times. What is wrong with their investigation plan? ADVANCED [+4 points]
Using the friction graph provided. Accurately identify each of the following:
|
EXPERT [+5 points]
Plan an investigation to compare the effects of different strengths of pushes and pulls on the motion of a ball using the following criteria:
|
/ v / Knowledge CheckSome students were trying out for the basketball team and wanted to know what the best sneakers were to reduce slipping during a game. The students were provided with a spring scale which is a tool used to measure a force, such as the force required to pull an object that consists of a spring fixed at one end with a hook to attach an object at the other.
