Name:__________________________ Period:______ Date:_____________________ Physics – Speed, Velocity, and Acceleration Worksheet (DO NOT WRITE ON WORKSHEET) 1. Match the word with the definition: Speed _____ a. A numerical value alone. Velocity _____ b. The magnitude of the velocity vector. Magnitude ______ c. How much ground an object has covered during its motion. Distance _____ d. The distance and direction of an object from a fixed reference point. e. Speed and direction. Displacement _____ 2. What two controls on a car cause a change in speed? What control causes only a change in velocity? 3. Give the standard units for the following: speed, velocity, distance, displacement, time, and acceleration. 4. What does the symbol ∆ mean? 5. Anne and Steve walk eastward with a speed of 0.98 m/s. If it takes them 34 minutes to walk to the store, how far have they walked? 6. If Dannika rides south on her bicycle in a straight line for 15 minutes with an average speed of 12.5 km/h, how far has she ridden? 7. Sydney drives her car with an average velocity of 48.0 km/h to the west. How long will it take her to drive 144 km on a straight highway? 8. A bus travels 280 km north along a straight path with an average velocity of 88 km/h to the north. The bus stops for 24 minutes, then it travels 210 km north with an average velocity of 75 km/h to the north. a. How long does the total trip last? b. What is the average velocity for the total trip? 9. A car is at a red light. When the light turns green, the car increases its velocity from rest to 31 m/s in 14.7s. What is the car’s acceleration? 10. As a bus comes to a sudden stop to avoid hitting a pedestrian, it accelerates uniformly at -4.21 m/s2 as it slows from 9.0 m/s to 0 m/s. Find the time interval of acceleration for the bus. 11. A car with an initial speed of 23.7 km/h accelerates at a uniform rate of 0.92 m/s2 for 3.6 s. Find the final speed and displacement of the car during this time. 12. A car traveling initially at +7.0 m/s accelerates uniformly at the rate of +0.80 m/s2 for a distance of 245m.
