Study Guide 1. Define the following concepts: a. Position b. Displacement c. Distance d. Velocity e. Acceleration 2. A student walks north for 50 m then turns on the spot to walk 25 m east. What is the difference in magnitude between the total distance travelled and displacement? 3. The position-time graph of an object is given below. Position (m) 70 30 0 0 3 Time (s) Calculate the average speed of the object between 0 and 7 s. 4. Two locomotives approach each other on parallel tracks. Each has a speed of 155 km/h with respect to the ground. If they are initially 8.5 km apart, how long will it be before they reach each other? <-8.5 km- 155 km/h Um 155 km/h Velocity plans mel 5. The graph below shows the variation with time t of the velocity v of a body. 3t 4t Time (s) What is the average speed of the body between 0 and 4t? 6. State with Graph corresponds to A, B and C • A shows a constant velocity - there is no acceleration. This is known as uniform motion. .B shows the velocity changing at a constant rate. This is known as uniformly accelerated motion and the body has uniform acceleration. •C shows the velocity changing at a rate that is not constant. This is known as non- uniformly accelerated motion and the body has non-uniform acceleration. Time Velocity Time Velocity Time
