Use the velocity-time table for a cart moving east. What is the cart's acceleration?
Use the velocity-time table for a cart on a north-south track. Taking north as positive, what is the cart's acceleration?
Use the table for a glider on an east-west track. Taking east as positive, what is the glider's acceleration?
Use the velocity-time table for a skateboarder moving east. What is the skateboarder's acceleration?
Use the table for an elevator. Taking upward as positive, what is the elevator's acceleration?
Use the table for a train moving east. Taking east as positive, what does the data show?
Use the table for a cyclist. Taking east as positive, what does the data show?
Use the table for a runner moving east. What does the data show about the runner's acceleration?
What does acceleration measure?
Which SI unit is used for acceleration?
Why is acceleration a vector quantity?
Which motion can involve acceleration even when speed stays constant?
In the formula a = (vf - vi)/Δt, what does vf - vi represent?
What does a negative acceleration mean when the positive direction is defined?
A lab report lists an acceleration as 3.0 m/s² east. What is 3.0 m/s²?
A car traveling east slows from 30 m/s to 12 m/s in 6.0 s. Take east as positive. What is its acceleration?
A runner starts from rest and reaches 8.0 m/s north in 4.0 s. What is the runner's average acceleration?
A bicycle moving west speeds up from 6.0 m/s to 18.0 m/s in 3.0 s. Take west as positive. What is its acceleration?
A cart moving east at 5.0 m/s has a constant acceleration of 2.0 m/s² east for 7.0 s. What is its final velocity?
A train moving east at 20 m/s has an acceleration of -1.5 m/s² for 8.0 s. Take east as positive. What is its final velocity?
A scooter starts from rest and reaches 24 m/s with a constant acceleration of 3.0 m/s². How long does this take?
A cart slows from 15 m/s to 3.0 m/s with a constant acceleration of -2.0 m/s². How much time passes?
A toy car has vi = -4.0 m/s and vf = +8.0 m/s over 3.0 s. Taking east as positive, what is its acceleration?
A dropped ball starts from rest. If upward is positive and a = -9.8 m/s², what is its velocity after 2.5 s?
A ball is thrown upward at 18 m/s. Ignoring air resistance, about how long until it reaches its highest point? Use a = -9.8 m/s².
A cart's velocity changes from -12 m/s to -3.0 m/s in 3.0 s. Taking east as positive, what is its acceleration?
A cart's velocity increases from 2.0 m/s to 14.0 m/s in 6.0 s along a straight track. What is its average acceleration?
A ball is thrown straight up. At the highest point, its velocity is momentarily zero. Ignoring air resistance and taking upward as positive, what is its acceleration?
A puck glides in a straight line at a constant velocity of 4.0 m/s east. What is its acceleration?
A car moves around a circular track at a constant speed. Which way does its acceleration point?
A cart moves west on a long track while its acceleration points east. If that acceleration stays constant, what happens to the cart's motion?
An object has negative velocity and negative acceleration on the same straight track. What happens to its speed?
Can an object moving at 25 m/s have zero acceleration?
A drone changes from moving north to moving east while keeping the same speed. What must be true?
On a velocity-time graph, a straight horizontal line represents what acceleration?
A cart's velocity changes by the same amount during each equal time interval. What kind of acceleration does the cart have?
During equal 1.0 s intervals, a runner's velocity increases by 1 m/s, then 2 m/s, then 3 m/s. What does this show?
A cart moves in the positive direction but has negative acceleration. What can you conclude about its speed?
A cart moves in the negative direction but has positive acceleration. What can you conclude about its speed?
