The Physics Around Us by Brendan Mcguire https://padlet.com/bmcguir1/996on650yah An in depth look at the physics we experience everyday en-us 2019-01-29 01:01:42 UTC 2019-02-05 01:17:22 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Planets.png What we will learn bmcguir1 https://padlet.com/bmcguir1/996on650yah/wish/325206852 In this course we will be utilizing physics in order to calculate and understand events that occur around us every day. This could be anything from why we fall back to the Earth when we jump, or why its easier to move an object up a ramp over simply picking it up.]]> 2019-01-29 01:09:02 UTC https://padlet.com/bmcguir1/996on650yah/wish/325206852 bmcguir1 https://padlet.com/bmcguir1/996on650yah/wish/325207864 Please feel free to post your answers to the questions I posed here, as well as any questions you have for me about these questions or anything Physics related.]]> 2019-01-29 01:13:15 UTC https://padlet.com/bmcguir1/996on650yah/wish/325207864 What is Physics in one dimension bmcguir1 https://padlet.com/bmcguir1/996on650yah/wish/325208035 When I talk about Physics in one dimension what i mean is that an object is moving in a straight line with no deviation from this path. It is going one way and that is the only path that it is taking.
Here is a little visual to help illustrate this idea.]]> 2019-01-29 01:14:11 UTC https://padlet.com/bmcguir1/996on650yah/wish/325208035 Equations to help bmcguir1 https://padlet.com/bmcguir1/996on650yah/wish/325208961 As with most sciences we will be using some equations to make our calculations and the ones I want you to use for this sections problems are:
  • Dx=vxt for horizontal distance
  • vy=vyo-gt for vertical velocity
For these equations D is distance, v is velocity with the subscript showing the direction, t is time, and g is gravity which is 9.8 m/s2 .

1. If I throw a ball straight up at 10 m/s, how fast will it be going 1 second later?
2. A car is rolling along a flat street, assuming no friction, going 20 m/s, how far will the car travel after 60 seconds?
3. If I drop a rock into a well how fast will the rock be going 3 seconds later right before it hits the water]]> 2019-01-29 01:25:17 UTC https://padlet.com/bmcguir1/996on650yah/wish/325209900 Focus for this class bmcguir1 https://padlet.com/bmcguir1/996on650yah/wish/325210021 For our first class we will be starting our Kinematics topic by starting with motion in one direction. This will allow us to analyze the important foundation for the more complex topics to get a strong base for future classes to build on.]]> 2019-01-29 01:26:06 UTC https://padlet.com/bmcguir1/996on650yah/wish/325210021
