Topic: Forces and Newtons Laws
Understand and apply the relationship between force, mass and acceleration.
F=ma
Acceleration is applied through force. Mass is the turbine. The force acting upon it is the water flowing that causes acceleration. So the greater amount or weight of water on the mass, the greater the acceleration. Acceleration depends on force and the distance force moves the water.
Topic: Velocity and Momentum
Explain real life phenomonon in terms of v and m.
p=mv
The greater amount of water hitting the wheel the higher the speed and the faster it will move. The less quantity of water will decrease momentum. Velocity is the speed and direction applied to how the water will be hitting the turbine will give it a certain momentum depending on the mass. The velocity of the water hitting the blades which will create a certain momentum. The greater the mass will create less velocity due to their inverse relationship. A water turbine and how it works is an example of a real life phenomonon in terms of v and m.
Anita worked on a paper model of a fan with construction paper, paper cup, and nail ...The pictures posted will show examples. Over the weekend i will come up with another design to give us more ideas for our project.
Thanks, Helen!!
