The Project - Rubber-band Powered Toy Car

This is the project. You are going to make rubber-band powered toy car

Your nephews birthday is coming and he told you that he wanted to have a toy car like this. 
You don't have money to buy it, so you come up with a plan that instead of buying it, you are just going to create one. (So you're going to create one). 

How to create a toy car instruction video



There are plenty of instructional videos on youtube on how to create a rubber-band powered toy car, Just type the "Rubber-band powered toy car" or check for the videos of "granddadisanoldman"

How your work will be graded? 
Design (paint it, put some stickers on it, come up with a cool design, there are plenty of designs in youtube, add some paraphernalia if you want, put flag, make it a formula racer) = 30 percent
Resourcefulness ( No need to buy the materials in the hardware or in the grocery, you can use materials in your backyard or in your garbage can, you can recycle) = 30 percent
Explanation (You will explain to us how you designed your work in front of the class, what makes your car better than the other car, time to tell to everyone your secret formula using the law of science specifically Newtons' law) = 40 percent

Note: A racing competition will take place, that car that covers the greatest distance will have an additional 25 percent. Deadline will be announce in class. 

Goodluck!

Newton's Law of Motion Project

Hello guys, this will be the performance task that you are going to create for our topic Newton's Law of Motion. Before I tell you the details about the project, let's have  a summary first of what are the Newton's Laws of Motion. 

First Law - Law of Inertia
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
 Here, eventhough the car stopped, the body still moves forward


Second Law - Law of Acceleration
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
 Here, the more force you need to pull the big rock.

Third Law - Law of Reaction
For every action, there is an equal and opposite reaction.
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs. 
 Forces are always in pair, and they always go at opposite direction. 
This is it for now, I'll tell you the instruction for the project next time. :)
