Practice for Quiz #4:

What is the correct formula for velocity?

• Force / Acceleration

• Displacement / Time

• Time / Displacement

• Acceleration / Force

The following data was collected. What does it mean when data cells are shaded gray (like the Velocity and Trend data shown below)? Table titled "Velocity of Toy Car using 1 Photogate" with columns: Position of Photogate from Dark Mark (m), Displacement of Flag through Photogate (m), Time Through Photogate (s), Velocity through Photogate (m/s).

• The data is measured

• The data needs is calculated and/or analyzed

• The data is incorrect (there is an error)

• The data is changing

The following data was collected. What would you type into cell D3 (column D, row 3) in order to calculate the Velocity (what is the code you would type)? Table showing: - Position of Photogate from Dark Mark (m) - Displacement of Flag through Photogate (m) - Time Through Photogate (s) - Velocity through Photogate (m/s) With values: 0.00, 0.010, 0.0089

• =B3/A3

• =A3/B3

• =C3/A3

• =C3/B3

• =B3/C3
