Speed And Velocity
What I think velocity means in my own words is the speed of an object or person in a given direction. The variable is always v and the units are meters per second. What I think speed means is the rate of an object or person that is able to move or operate, the act of moving rapidly. The difference between speed and velocity is that speed is just something/someone moving and velocity is the same thing but in a given direction.
Example of Average Velocity: Jackson ran from 4 meters to 16 meters in a road within 8 seconds. What was his average velocity?
16-4=? (finial initial subtracted by starting initial)
12 meters/8 seconds (using average formula)
final answer: 1.5 meters/second
Example of instantaneous velocity: I threw a pencil from 0 meters to 6 meters at 3 seconds. What is my instantaneous velocity?
Instantaneous velocity wouldn't have a 3 second time period. It's during that exact moment in time, like when you look at your speedometer - that is the speed you are going that instant.
