Function Documentation

zsl_phy_work_kin()

int zsl_phy_work_kin	(	zsl_real_t	k1,
		zsl_real_t	k2,
		zsl_real_t *	w
	)

Calculates the work required to change the kinetic energy of an object from 'k1' to 'k2'.

Parameters

k1	Initial kinetic energy of the object in joules.
k2	Final kinetic energy of the object in joules.
w	Pointer to the output work in joules.

Returns

0 if everything executed properly, error code on failure.

zsl_phy_work_module()

int zsl_phy_work_module	(	zsl_real_t	f,
		zsl_real_t	d,
		zsl_real_t *	w
	)

Calculates the module of the work done by a force (f) along a distance (d).

Parameters

f	Applied force in newtons.
d	Distance in meters.
w	Pointer to the output work in joules. Will be set to NAN if either the force or the distance are negative.

Returns

0 if everything executed properly, error code on failure.

zsl_phy_work_x()

int zsl_phy_work_x	(	zsl_real_t	f,
		zsl_real_t	d,
		zsl_real_t	theta,
		zsl_real_t *	w
	)

Calculates the horizontal component of the work done by a force (f) along a distance (d).

Parameters

f	Applied force in newtons.
d	Distance in meters.
theta	The angle between the force and distance vectors.
w	Pointer to the output work in the x-axis in joules. Will be set to NAN if either the force or the distance are negative.

Returns

0 if everything executed properly, error code on failure.

zsl_phy_work_y()

int zsl_phy_work_y	(	zsl_real_t	f,
		zsl_real_t	d,
		zsl_real_t	theta,
		zsl_real_t *	w
	)

Calculates the vertical component of the work done by a force (f) along a distance (d).

Parameters

f	Applied force in newtons.
d	Distance in meters.
theta	The angle between the force and distance vectors.
w	Pointer to the output work in the y-axis in joules. Will be set to NAN if either the force or the distance are negative.

Returns

0 if everything executed properly, error code on failure.
