mnmtacos back story!

Hello!  We thought it might be a good idea to give you guys a little more information on who we are and why we are here!  First off, mnmtacos is created by two people: Meg and Patrick.  We are in a homeschool co-op where we do science and this blog is a unit test our teacher wants us to do instead of taking an actual end-of-the-year test!  We hope that our explanations are straightforward and simple.  Also, that they help you to understand the topics a little bit better.    

Force and motion: module 10: what are Newton's three laws?

Newton's three laws of motion are the groundwork of physics.  Those three laws were finished in less than 18 months.  The first law, also known as inertia, states that an object's velocity will not switch unless acted on by an outside force.  The second law states when an object is maneuvered on by an outside force, the force is equivalent to the mass of the object times the resulting acceleration.  The third law states that "For every action, there is an equal and opposite reaction."

Force and motion: module 10: what is friction?

Friction is created when two surfaces meet.  An example would be when a person rolls a ball on the ground.  It will eventually stop because of the friction between the two surfaces.

Force and motion: module 10: what is force?

A force is basically a push or a pull applied on an object in an attempt to switch that object's acceleration.  An example would be let's say two people were traveling in a car.  The car just so happens to run out of gas on them.  One of the two has to push the car to the nearest gas station.  The person pushing the car is using force.





Equation:  f= mass x acceleration


                 m= force/acceleration
          
                 a= force/mass

Force and motion: module 9: what is free fall?

Free fall is the case of an object that is falling facing the earth with nothing forbidding its fall.  An example would be like falling without air resistance.

Force and motion: module 10: what is momentum?

Momentum is the amount of motion of a moving object.  An example would be a train going 2,000 m/h has a very large amount of momentum.

Equation:  mass x velocity

Force and motion: module 9: what is acceleration?

Acceleration is a sudden change in an object's velocity.  An example would be a horse galloping at a velocity of 45 m/h west then quickly switched to 55 m/h north.

Equation: final velocity - initial velocity/time

Force and motion: module 9: what is speed?

Speed is how fast an object is moving.  An example would be a car going 43 m/h.

Equation:  distance/time

Force and motion: module 9: what is velocity?

Velocity is speed with direction; an example would be a train going north at 65 m/h.

Equation: distance/time north

Force and motion: module 10: what is inertia?

Inertia is Newton's first law.  It states that if an object is going a certain velocity, it will not change unless an outside force forces it to change.  An example would be if a bike is laying on the ground, and a little girl stands up the bike and starts riding away.  The velocity of the bike changed by an outside force.

If you're using Exploring Creation with Physical Science by Dr. Jay L. Wile and reading module 9-11, you should read our blog!  In our blog we will be focusing on: inertia, velocity, speed, acceleration, momentum, free fall, force, friction, and Newton's laws.
