Motion. An object is in motion if its distance from another object is changing, or it changes position relative to a reference point.

Motion. Motion terms and their definitions: position:distance and direction from a reference point motion:change of position over a time interval example:

Chapter 1: Matter in Motion  Motion= a change in position over time  Reference point= an object that stays in place and shows us that something is moving.

Linear Kinematics - Speed

Speed –– the rate of motion vavg - average speed (m/s, f/s, mph, km/hr) x - distance (m, cm, feet, miles, km) t, - elapsed time (seconds, minutes, hours)

Whiteboards: Speed 1-6

A runner covers 100 m in 13.48 s What is their speed solution 7.42 m/s

A person running 8.30 m/s covers what distance in 113 s? solution 937.9 m

What time does it take a baseball going 132 f/s to go 82 feet? solution 0.6212 s

How far does a car going 26.82 m/s go in 60 seconds solution 1609.2 m

A car going 26.82 m/s takes how much time to go 3,200 m? (3.2 km) solution 119.3 s
