Graphing Motion
The type of graph that shows how an object's position changes over time
What is a position vs. time graph?
The total length of path traveled by an object
What is distance?
What is speed?
The rate of change of velocity
What is acceleration?
The displacement of an object if v = 20 m/s and t = 5 s
What is 100 meters
The slope of a [v vs. t] graph
What is acceleration?
The vector quantity that represents the straight-line distance from start to finish
What is displacement?
The quantity that includes direction and magnitude
What is velocity
The type of acceleration when an object slows down
What is deceleration (negative acceleration)
The acceleration of a car starting from rest reaching a speed of 30 m/s in 6 seconds
What is 5 m/s2
The area under a [v vs. t] graph's line
What is displacement?
When distance and displacement are the same
What is when an object moves in a straight line in one direction?
When changing direction, speed stays the same but velocity
What is changes? (velocity relies on direction)
Acceleration when moving at a constant velocity
What is ZERO
The final speed of a runner starting from rest, accelerating at a rate of 2 m/s2 after 4 seconds
What is 18 m/s
When a position vs. time graph shows a straight line with a positive slope
What is constant positive velocity?
Your displacement when you walk 10 meters East then 10 meters West.
What is ZERO?
The difference between instantaneous and average velocity
What is instantaneous is at a certain point, and average measures over a certain time
The value of the acceleration of an object falling near Earth
What is -9.81 m/s2
The height of a building if an object is dropped from rest, reaches a velocity of -30 m/s, and falls at a rate of -9.81 m/s2
45.9 meters tall
The average acceleration found from a [v vs. t] graph using two points
What is: (v2-v1)/(t2-t1)
What is: Slope formula
The formula used to find the total displacement
What is Δx = xf - xi
When an object moves at a constant speed in a circular motion
What is velocity changes
The value of the acceleration in the x-direction of an object kicked horizontally off of a building
What is ax = 0 m/s2
The horizontal distance that a golf ball travels when hit with a velocity 25 m/s at an angle 60 degrees above the horizontal. Hint: Find components, find the hang time, then find dx
What is dx = 55.3 m
