Definition: For Today Class!
Newton First Law: The law that a particle not subjected to external forces remains at rest or moves with constant speed in a straight line.
Force: Push or Pull.
Inertia: The ability of an object to resist changes in its state of motion is a fundamental property of all matter
Weight: The force that gravity exerts on an object due to its mass [SI unit is the Newton]
Mass: the quantity of matter an object contains [SI unit is the kilogram]
Gravitational force: is an attraction between two objects because of their mass
Friction: A force opposing the relative motion of two objects that are in contact.
We started the class by watching video, the video that Mrs. K wants to show us last week. The title of the video is Newton’s 1st law by Paul Hewitt. Our task for the class today is to understand the video and Write down 7 interesting that you learned in the video. The summary of the video are about Inertia, force, gravitational force, mass, weight, velocity, and acceleration. Also, from the video they talk about the homework last week on the book Pg.37 # 1. After we done watching video we continue to talk about the free –body diagram for objects on an inclined surface (page 17 # 7 & 8).
Mrs.K wants us to answer the FF.
Page 40 (#8,9,10) the one that we skipped last Monday because we did not study the object on an inclined surface.
Page 41 (#1-8)
Page 42 (#9&10)
Lastly Mrs. K said that be prepare for our First lab tomorrow. Read the worksheet that she gave to us (Force and Acceleration).
