SPH3UO 1A) Uniform Motion: Position-Time Graphs Kinematics Unit: Graph Analysis Package I for Uniform Motion Page 1 of 4 PART A: Complete the following statements using the following words: forward 1. The position-time graph for an object with a backward constant zero slope (used 2 times) 2 . The velocity is a straight line with constant slope. of the position-time graph for an object moving at a constant velocity gives the value of the velocity. 3. On a position- time graph . a positive slope represents a a zero slope represents a velocity. velocity, and a negative slope represents a velocity 4. The average velocity between two points on a position-time graph : the of the straight line joining the two points. PART B: Answer questions 1 to 4 below in the space provided. 200 C The following graph shows the motion of an 15 B inspector on a refrigerator assembly line. E Position zero is the start of the assembly Position d(m[from start]) 100 line. Use positive to represent directions 50 away from, and negative to represent directions toward , the start. 0 0 40 60 80 100 120 140 160 180 200 1. How far is the inspector from the starting point after: (c) 80 s (b ) 40 s (a) 20 s (c) 125 m 2. When is the inspector at the following positions: (b) 150 m (a) 50 m E 3. What is the inspector's velocity during each of the lettered intervals? D A (iv) average speed (iii) average velocity 4. For the entire trip what is the inspector's: (ii) distance (1) displacement 5.
