describe rotational speed. Hint: think of ant example! | Rotational speed (is sometimes called angular speed) is the number of rotational per unit of time. All parts of the wheel rotate about their axis in the same amount of time. (think of ant example!)

What is the centripetal force equation? calculate centripetal force | Fc= mv^2 / r
v^2 is the centripetal acceleration because F=ma, c equals Fc=maC (centrip. accel.) Ac= v^2/r Sample prob.: Calc. the tension in a 1-m long dog leash that whirls a 2-kg dog at 5 m/s in a horizontal circle.

give examples of centripetal force. | When you turn around the corner in your Lamborghini the sideways friction btwn. the tires and road creates a centripetal force that holds the car on a curved path.

explain why centrifugal force is “fictitious.” | Centrifugal force is fictitious because it is away from the center and the gravity is pushing outward.

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.
