Question

You perform an experiment in which you measure the distance traveled by a projectile fired with different initial velocities. Which piece of technology is appropriate for gathering the experimental data you need?
A. Scale
B. Computer
C. Tape measure
D. Thermometer

Answer 1

The correct answer is C. Tape measure

Explanation:

In an experiment, the technology or instrument that is appropriate for gathering experimental data mainly depends on the factors or variables to be studied. In this way, a scale would be useful for gathering information related to mass; a thermometer for gathering information related to temperature; a computer for analyzing numerical information or large amounts of information and a tape measure in the case of gathering information about distance. This implies if you are measuring the distance of a projective with different initial velocities the best is to use a tape measure as this measures distance in millimeter, centimeters, and meters and therefore it is useful to know in numbers the difference of each projectile.

Answer 2

During the motion of projectile we know that the distance traveled by the object is in the range of meter

So the object will move to certain distance at different velocity which we have to measure by a device which has range of distance from 0 meter to several meters

So the correct device to measure it is

$C. Tape Measure$
