Tuesday
(6 Oct):
Key
Concept's) Today: Finish
2nd Law & Start Newton's 3rd law
Journal: Demo-
Rubber band and Cart
1. What is the
direction of net force on the cart?
2. What is the
direction of acceleration of the cart?
3. When the cart
reached the farthest point, explain is its velocity, net force and
acceleration (compared to the rest of the positions)
Journal:
1. Using Newton's
3rd law, explain the difference between starting to walk on ice (no
traction) and starting to walk dry cement.
2. Demo: Flight of a
balloon - What would happen if this balloon was in space (no
atmosphere)?
:
Newton’s Three Laws
Learning Objectives:
- Differentiate
between mass and weight and the relationship with gravity
- Demonstrate
proficiency in solving problems using displacement, distance,
inertia, speed, velocity and average acceleration.
- Analyze the effects
of balanced and unbalanced forces on the motion of an object
- Predict & analyze
motion of an object based on inertia and forces (balanced and
unbalanced)
- Demonstrate
understanding of Free Body Diagrams by drawing Free Body diagrams
for static, constant velocity and accelerated motion for single
bodies and multiple attached bodies.
- Demonstrate
proficiency in solving problems using Newton’s 1st, 2nd,
& 3rd, Laws of Motion
- Generate and
evaluate questions that can be answered through
scientific
investigations.
-
Apply understanding by planning, conducting,
reporting and evaluating systematic and complex scientific
investigations of objects, events, systems, and/or processes.
- Analyze local,
regional, national, or global problems or
challenges in which scientific
design, technology or engineering can be or
has been used to find a solution.
