vj_simulate: Vertical Jump Simulation

In mladenjovanovic/vjsim: Vertical Jump Simulator

Description

Simulates vertical jump using Runge-Kutta method

Usage

vj_simulate(
  mass = 75,
  weight = mass * gravity_const,
  push_off_distance = 0.4,
  gravity_const = 9.81,
  time_step = 0.001,
  save_trace = TRUE,
  fgen_func = fgen_get_output,
  iter = FALSE,
  max_iter = 1000,
  ...
)

Arguments

mass	Numeric value. Default is 75kg
weight	Numeric value. Default is mass * gravity_const
push_off_distance	Numeric value. Default is 0.4m
gravity_const	Numeric value. Default is 9.81
time_step	Numeric value. Time step used in simulation. Default is 0.001
save_trace	Logical. Default is TRUE
fgen_func	Function used to represent Force Generator. Default is fgen_get_output.
iter	Logical. Default is FALSE
max_iter	Numeric value. Default value 1000
...	Forwarded to fgen_func

Value

List object with summary data frame and trace data frame

Examples

vertical_jump <- vj_simulate(
  mass = 85,
  push_off_distance = 0.4,
  time_step = 0.001
)

round(t(vertical_jump$summary), 3)

plot(
  x = vertical_jump$trace$distance,
  y = vertical_jump$trace$velocity,
  type = "l"
)

plot(
  x = vertical_jump$trace$time,
  y = vertical_jump$trace$ground_reaction_force,
  type = "l"
)

plot(
  x = vertical_jump$trace$distance,
  y = vertical_jump$trace$ground_reaction_force,
  type = "l"
)
