### 4 Multiple Choice Questions

1. round the answer so that it has the same number of significant figures as the measurement with the fewest significant figures
2. A physical measurement that does not contain directional information
3. The time rate of change of an object's velocity

a=change V/change t

The slope of a velocity versus time curve is the acceleration.
4. the time-rate at which a body changes its position; defined as displacement divided by the time of travel

V=Change in x/Change t

### 4 True/False Questions

1. Vector quantityA physical measurement that contains directional information

2. Average VelocityThe velocity of an object over an extended period of time

The slope of a position versus time curve is the velocity

3. Significant figures Rulesa digit within a number is significant if:
I. It is non-zero
II.It is a zero between two significant figures or
III. It is a zero at the end of the number and to the right of the decimal point
