Answer on Question #61615-Physics-Mechanics-Relativity

In an experiment involving the spiral spring, $F$ is the restoring force and $x$ the extension of the spring. The equation $f = -kx$ gives the relationship between $F$ and $X$ . The graph of $f / n$ against $x / cm$

A. passes through the origin

B. has an intercept on the vertical axis

C. has an intercept on the horizontal axis

Answer

The extension of an elastic object is directly proportional to the force applied to it:

$$F = k \cdot e$$

F is the force in newtons, N,

k is the 'spring constant' in newtons per metre, N/m,

e is the extension in metres, m.

The graph of force against extension produces a straight line that passes through the origin. The gradient of the line is the spring constant, k. The greater the value of k, the stiffer the spring.

Answer: A. passes through the origin.
