the height of the track to the cart’s acceleration? The data shows that sinӨ‚ which is dependent on the height‚ is getting higher as acceleration is increasing. This implicates that when object is at higher altitude‚ its acceleration is faster. 2. From the data obtained‚ how is time‚ t related to the inclination of the track? Explain why? Time and position of velocity are interrelated to each other and the height and gravitational pull affects the acceleration of a moving and a free falling object

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. The vectors appear to have both direct and inverse relationships with each other. When I move the ball one direction‚ both of the vectors move the

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
