vector or scalar quantities. Of particular interest‚ the forces‚ which operate on a flying aircraft‚ the weight‚ thrust‚ and aerodynamic forces‚ are all vector quantities. The resulting motion of the aircraft in terms of displacement‚ velocity‚ and acceleration are also vector quantities. These quantities can be determined by application of Newton’s laws for vectors. The scalar quantities include most of the thermodynamic state variables involved with the propulsion system‚ such as the density‚ pressure

5. acceleration – change in speed over time (vector quantity) TWO types; a. Linear acceleration – speed up or slow down b. Centripetal acceleration – change direction B. Centripetal acceleration (ac) – acceleration changes due to change in direction. 1. Centripetal means center seeking 2. ac is always directed toward the center of the curved path (circle) 3. If an object is moving in a circle it will always have a centripetal acceleration 4. ac

It then moves at constant velocity for another 20.0 min before it slow down and finally stopped in another 10.0 min. Find (a) acceleration during the first 15 min‚ (b) the deceleration during the last 10 min of its motion‚ (c) the distance traveled during the last minute‚ and the (d) total displacement.

Reading Assignment #1: Vector Analysis Textbook Sections that I read: 2.1-3 Important Concepts: An interaction between two objects can be described and measured in terms of two forces. The force is a push or either a pull. There are two types of forces. #1 is a long range force and this force does not require the objects involved to be touching each other. An example of this is when you are holding a magnet away from a refrigerator and you are able to feel the magnetic pull. #2 is a contact force

quantity that refers to "how much ground an object has covered" during its motion. * Displacement: Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object’s overall change in position. * Acceleration: Change in speed per time. Distance-time Graphs: Uniform Speed: In uniform speed‚ Uniform Velocity means the object on the graph is moving equal distances in equal time. This is why the sloped line (gradient) is a straight line.
