Kinematics: Speed and Velocity Quiz
Quiz Overview
Description
Speed is the rate of motion, or the rate of change in position. It is a scalar expressed in terms of distance moved per unit time. This is the formula for speed:
Speed = distance/time
Units include miles per hour (mph), km/hr, m/s
Example: What is the speed of a car that is traveling 10 miles every 5 minutes?
Distance: 10 miles. Time: 5 minutes.
Speed = 10 mi/5 min = 2 mi/min
The car travels two miles every minute.
Speed is the magnitude component of velocity. Velocity is a vector, which means it has both speed and direction. The formula for velocity is the same as speed, except it includes a direction component.
For the following quiz, you will need a pencil, scratch paper and a calculator. Read each question carefully and select the best answer from the choices.
