question 8
which one of the following choices is an example of a conservative force?
motor propulsion force
gravitational force
tension
static frictional force
normal force

Explanation:

A conservative force is a force where the work done in moving a particle between two points is independent of the path taken. Gravitational force is a classic example of a conservative force. Motor propulsion force is non - conservative as it depends on the path (related to energy consumption for movement). Tension can be non - conservative in some complex systems (e.g., when there is energy loss due to stretching and relaxation in non - ideal cases). Static frictional force is non - conservative as the work done against it depends on the path. Normal force usually does no work in the traditional sense (when the displacement is perpendicular to the force), but when it does work (in non - ideal scenarios), it is non - conservative.

Answer:

gravitational force
