MOTION IN A STRAIGHT LINE

A distance vs. time graph shows an object's

• frame of reference
• speed
• acceleration
• favorite food

All motion is described as relative because

• how do you ever really know if something is in motion
• motion means different things to different people
• everything in the universe is constantly in motion, so it depends on your frame of reference

Kinematic equations links all of these things together

• time, space, and speed

• motion, acceleration, and force

• time, position, velocity, and acceleration

• force, acceleration, rate, and Roxann

 The graph shows Ashley riding her bike to Maria's house. 
What is occurring from point A to point B?

• they are traveling at a constant speed
• they are decreasing in speed
• they stopped to take a break
