Which entry from a force-table experiment is the measurement that cannot be complete without saying which way it acts?

In a track workout, which quantity describes the path length covered rather than the overall change in position?

On a straight track, east is chosen as positive. Which quantity can be positive or negative depending on the direction of motion?

A lab report lists 4.0 kg, 18 °C, 12 J, and 6.0 N east. Which entry describes a push or pull rather than just an amount?

Which quantity is a measure of how much matter an object has, not the gravitational pull on it?

East is chosen as positive. A cart rolls west at a steady 2.0 m/s. Which value correctly reports the cart's velocity?

A climber's data include total path length, energy used, elapsed time, and average acceleration. Which one must be stated with direction?

Which measurement is not tied to a direction even when the object turns during the motion?

Which lab quantity is the pull due to gravity on an object and therefore needs a direction for a full report?

A student writes a cart's displacement as 2.5 m. What else is needed to make the report complete?

Which SI unit is appropriate for an acceleration measurement?

A radar display gives a plane's speed as 240 m/s. What must be added to report the plane's velocity?

Which unit belongs with momentum in an SI physics calculation?

A force sensor report says only 15 N. What information is missing for a complete force measurement?
