A rollerblader's velocity is negative and their acceleration is positive. Which of these statements describes the rollerblader's motion? Choose the correct answer.
The rollerblader is speeding up
The rollerblader is slowing down
The rollerblader is remaining at rest
The rollerblader is traveling at constant speed
What quantity can you find by looking at the slope of a position vs time graph? Choose the correct answer.
Acceleration
Displacement
Average Velocity
Speed
C-E-R means: _____, _____, _____
(enter your answer all lowercase, separated by a comma and a space in between each word)
(a)
When does an object have an acceleration?
When it has a speed
When it changes velocity over time
When it moves to the right
When it remains still
The stage choreography for a play requires an actor to walk 9 steps to the right, 4 steps to the left, and then 4 to the right to be standing over the trapdoor. What is the actor's distance traveled and their displacement?
17 steps; +9 steps
9 steps; +4 steps
9 steps; -4 steps
8 steps; +9 steps
Is an object moving north at a constant velocity of 2 meters per second accelerating?
no: when an object has constant velocity, its speed and direction are not changing. Therefore, the object is not accelerating.
no: when an object has a constant speed, regardless of the direction it's going, it's not accelerating.
yes: when an object has constant velocity, it is accelerating.
yes: the object is accelerating because it is moving north
A person walking down a hallway, a moving train car, and a rolling bowling ball are examples of ___________.
one-dimensional horizontal motion
one-dimensional vertical motion
two-dimensional horizontal motion
two-dimensional vertical motion
What is the equation to calculate velocity?
displacement over time
distance over time
velocity over time
acceleration over time
Determine whether the question asks you to find an average velocity, not an instantaneous velocity. Select all that apply to asking about an average velocity scenario.
How fast must you bike to get somewhere in half an hour?
What is the fastest you can run?
What is the minimum speed for takeoff?
How fast did he run the first 5 miles of the marathon?
The unit of linear acceleration is
sm
s2 m
s2 rad
