Civil War Science & Tech

There were many good questions asked on yesterdays blog. Pick one and see if you can find the answer and post it. 

Civil War Science

During the next week we will be discussing what science and technology was developed during the civil war era. Please write a question you have about science and technology in the civil war. 

End of Newton

We have been studying Newton’s Laws.  Do you feel you know more about Newton’s Laws now? What specifically have you learned that you did not know?

Lab this Week

Which of Newton's Laws have you observed in this weeks lab work? 

Newtons Laws and Friction

A car skids on wet road and crashes into another car. Describe in detail what is happening using Newton's Laws and the three forms of friction.

Another Space Station Post

Yesterday you came up with a plan if the meteor heading for the space station had a greater mass. What difference do you think it would make if it had less mass yet a greater speed?

Save the Space Station

The meteor is heading for the space station. What plan would you come up with to prevent the meteor collision with the space station? Which of Newton's Laws would you use to explain why your plan would work? 

Action and Reaction

Imagine you are in the international space station and a meteor was heading toward the station. What effect would the meteor have on the orbit of the space station if it had a greater mass than the station?

Action and Reaction

For every action there is an equal and opposite reaction.  How would you increase the reaction of say a car hitting a wall? 

Design a Solution

Today we look at designing a solution to a problem involving Newton's third law.  The first step will be to define our criteria and constraints for the project. What is the meaning of criteria and constraints in science?   

Equal opposite or balance

Newton's third states that for every action there is an equal and opposite reaction.  How does this relate to balance and unbalanced forces? 

Back to the 2nd Law

A shot put has a much greater mass than a discus. How does Newton's second law explain why a discus can be thrown twice as far as a shot put? 

Third Law in Action

How does Newton's Third Law explain the direction a boat crew must move the oars in order to move the boat forward? 

What is Physics

Physics according to physics.org is "the study of matter energy and the interaction between them" 

With this in mind and from what we have study so far, please post a question about physics. 

You question should be thoughtful, in a complete sentence, and original. 

conservation of momentum

Suppose two spheres approach each other at 1 m/s from opposite directions. Their total momentum is zero. After the collision, they both zoom off at 1m/s in opposite directions. 

What is their momentum? 
What do you know about the mass of the two spheres? 

Transferring Momentum

When a player uses a golf club to hit a ball how is the momentum transferred? 

Can you stop this ?

What do you get when you multiply mass times velocity? 

speed or velocity

What is the difference between speed and velocity 

Is it distance or displacement

What is the difference between distance and displacement? Explain. 

Focus on Physics

Lets focus today on the contributions of  famous physicist. Pick one and post what their contribution was to science.
