What type of motion is being shown here?
|
Constant velocity, away from the starting point
|
|
|
What type of motion is being shown here.?
|
Constant velocity, but back to the starting point ( negative slope = returning to origin)
|
|
|
What type of motion is being shown here?
|
Stopped. Object is staying at the same position as time ticks by.
|
|
|
Which one of the lines -- a, b, or c -- has the highest constant velocity?
|
a, because it has the largest slope.
|
|
|
What motion is the object undergoing as time ticks by?
|
Constant velocity away; stopped; constant velocity return to origin
|
|
|
What motion is the object undergoing as time ticks by?
|
Accelerate away; stop; return to origin (neg. slope) at constant velocity.
|
|
|
What motion is occurring here?
|
Deceleration while moving away from origin, much like a ball thrown in the air as it reaches its peak.
|
|
|
What motion is occurring here?
|
Accelerating while moving back to the orgin, much like an upwardly thrown ball falling from its peak.
|
|
|
What motion is occurring here?
|
Decelerating while returning back to the origin, like a car coming to a stop at home.
|
|
|
What motion is occurring here?
|
Constant velocity (or zero acceleration) & is + or moving away from origin since it's in the 1st quadrant.
|
|
|
What motion is occurring here?
|
Acceleration, & since it's below the x-axis, it's moving in the negative direction.
|
|
|
What motion is occurring here?
|
Deceleration in the positive direction since it is in the first quadrant.
|
Dec (-) with (+) direction gives a (-) slope.
|

constant velocity
|
|
|
|
The steeper the slope on a Position -time (d-t) graph, the. ______ the velocity
|
faster
|
|
|
|
A horizontal line on a Position-time (d-t) graph means that the object is....
|
stopped
|
|
|
|
A horizontal line on a Velocity-time graph means the object has ____ acceleration or ______ velocity.
|
zero
constant |
|
|
|
_______ is how far an object moves without regard to the direction it goes.
|
Distance
|
|
|
|
______ is how far an object has been moved from where it started. Direction is important.
|
Displacement
|
|
|
|
_____ is how much an object speeds up or slows down.
|
acceleration
|
|
|
|
_____ is how far an object goes in a period of time. Direction matters.
|
Velocity
|

|
Slowing down (-) while moving backward (-) is _____ acceleration
|
positive
|
|
|
|
Speeding up (+) while moving backward (-) is _____ acceleration
|
negative
