Give an example of a variable force. Write the formula for Hooke's law.
(N/A) $1$. Example of a variable force: The gravitational force between two objects as their distance changes,or the spring force $F = -kx$ where the force depends on the displacement $x$.
$2$. Formula for Hooke's law: $F = -kx$,where $F$ is the restoring force,$k$ is the spring constant,and $x$ is the displacement from the equilibrium position.
