question #2
reference q.47176
what relationships in physics obey the kind of curve shown below, called a straight line or linear relationship? we also call this direct variation. (example: if a bike goes 1 m/s for 10 more seconds, it will drive 10 meters further.)

Explanation:

In Physics, many relationships are linear. For example, Hooke's law (force - displacement relationship for a spring, $F = kx$ where $F$ is the force, $k$ is the spring - constant and $x$ is the displacement), Ohm's law (voltage - current relationship in a resistor, $V=IR$ where $V$ is voltage, $I$ is current and $R$ is resistance), and the relationship between distance, speed and time ($d = vt$ where $d$ is distance, $v$ is speed and $t$ is time) as shown in the bike example. These all follow a straight - line or linear relationship on a graph.

Answer:

Hooke's law, Ohm's law, distance - speed - time relationship.
