Function Documentation

zsl_phy_mom_change()

int zsl_phy_mom_change	(	zsl_real_t	m,
		zsl_real_t	vi,
		zsl_real_t	vf,
		zsl_real_t *	p
	)

Calculates the gain or loss in momentum of an object based on its mass (m) and its initial (vi) and final (vf) velocities.

Parameters

m	Mass of the object in kilograms.
vi	Inital velocity in meters per second.
vf	Final velocity in meters per second.
p	Pointer to the output difference in momentum in kilograms and meters per second. Will be set to NAN if the mass is negative.

Returns

0 if everything executed properly, error code on failure.

zsl_phy_mom_elas()

int zsl_phy_mom_elas	(	zsl_real_t	m1,
		zsl_real_t	vi1,
		zsl_real_t	vf1,
		zsl_real_t	m2,
		zsl_real_t	vi2,
		zsl_real_t *	vf2
	)

Calculates the final velocity of an object after an elastic collision with another object given the final velocity of the other object and the masses and initial velocities of both objects.

Parameters

m1	Mass of the first object in kilograms.
vi1	Inital velocity of the first object in meters per second.
vf1	Final velocity of the first object in meters per second.
m2	Mass of the second object in kilograms.
vi2	Inital velocity of the second object in meters per second.
vf2	Pointer to the final velocity of the second object in meters per second. Will be set to NAN if any of the masses is negative or if the mass of the second object is zero.

Returns

0 if everything executed properly, error code on failure.

zsl_phy_mom_imp()

int zsl_phy_mom_imp	(	zsl_real_t	f,
		zsl_real_t	time,
		zsl_real_t *	imp
	)

Calculates the impulse given by a constant force acting during a certain period of time.

Parameters

f	Force applied in newtons.
time	Time in seconds.
imp	Pointer to the output impulse in newtons and seconds. Will be set to NAN if the time is negative.

Returns

0 if everything executed properly, error code on failure.

zsl_phy_mom_inelas()

int zsl_phy_mom_inelas	(	zsl_real_t	m1,
		zsl_real_t	vi1,
		zsl_real_t	m2,
		zsl_real_t	vi2,
		zsl_real_t *	vf
	)

Calculates the final velocity of the merged object after a perfect inelastic collision between two objects occur, given the masses and initial velocities of both the initial objects.

Parameters

m1	Mass of the first initial object in kilograms.
vi1	Inital velocity of the first object in meters per second.
m2	Mass of the second initial object in kilograms.
vi2	Inital velocity of the second object in meters per second.
vf	Pointer to the final velocity of the merged object in meters per second. Will be set to NAN if any of the masses is negative or if the sum of both masses is zero.

Returns

0 if everything executed properly, error code on failure.

zsl_phy_mom_mom()

int zsl_phy_mom_mom	(	zsl_real_t	m,
		zsl_real_t	v,
		zsl_real_t *	p
	)

Calculates the linear momentum in kilograms and meters per second of an object based on its mass (m) and velocity (v).

Parameters

m	Mass of the object in kilograms.
v	Velocity in meters per second.
p	Pointer to the output linear momentum in kilograms and meters per second. Will be set to NAN if the mass of the object is negative.

Returns

0 if everything executed properly, error code on failure.
