| The hands of a clock relative to the numbers on a clock or the speed of a bicycle relative to the direction of travel. Which of the following most closely illustrates motion by relating it to a reference point? | The hands of a clock relative to the numbers on a clock
🗑
|
||||
| What are two factors that determine speed? | distance and time
🗑
|
||||
| What is the difference between speed and velocity? | One has direction, and the other does not
🗑
|
||||
| What best represents acceleration as presented on a graph? | velocity change vs. time
🗑
|
||||
| What is an object that appears to stay in place that helps you detect motion in another object? | a reference point
🗑
|
||||
| What do you need to know to calculate an object's acceleration? | starting velocity
🗑
|
||||
| How do you calculate average speed? | divide the total distance traveled by the total time
🗑
|
||||
| What is the difference between speed and velocity? | velocity has direction, while speed does not
🗑

| A hiker's velocity begins at 1.8 m/s uphill and changes to 1.5 m/s uphill. How do you know the hiker has a negative acceleration? | his speed decreased
🗑
|
||||
| What is an object that appears to stay in place that helps you detect motion in another object? | a reference point
🗑
|
||||
| What do you need to know to calculate an object's acceleration? | starting velocity, final velocity, and time it takes to change velocity
🗑
|
||||
| What would you call a building if you compared it with a moving student? | a reference point
🗑
|
||||
| When something changes position, what is it doing? | It is moving
🗑
|
||||
| What two things does speed depend on? | distance and time
🗑
|
||||
| What is the SI unit for speed? | m/s
🗑
|
||||
| What is motion? | Any change in position over time
🗑
|
||||
| What is the speed of an object in a particular direction? | velocity
🗑
|
||||
| Your speed is not changing, but your direction is changing. What are you still doing? | accelerating
🗑
|
||||
| What is the driver's velocity if a driver's acceleration is positive? | increasing
🗑
|
||||
| What distinguishes the measurement of speed from that of velocity and acceleration? | speed does not involve direction, but both velocity and acceleration do
🗑
|
||||
| What is centripetal acceleration? | acceleration that occurs in a circular motion
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
