simulate point mass car acceleration in matlab

To simulate point mass car acceleration in MATLAB, you need to develop a mathematical model of the car that takes into account the forces acting on the car such as friction, gravity, and others. Here's a simple script that simulate the point mass car acceleration:

main.m
% Set up initial conditions
mass = 1000;            % kg 
throttle = 100;         % N
rolling_resistance = 10 % N
air_resistance = 20     % N
g = 9.81;               % m/s^2
F = throttle - rolling_resistance - air_resistance;
v(1) = 0;
x(1) = 0;
t(1) = 0;
dt = 0.1;

% Simulation loop 
for i=2:100
    % Calculate acceleration
    a = F / mass;
    
    % Calculate velocity and position 
    v(i) = v(i-1) + a * dt;
    x(i) = x(i-1) + v(i) * dt;
    t(i) = t(i-1) + dt;
end

% Plot results
plot(t, x);
xlabel('Time [s]');
ylabel('Position [m]');

The script simulate the acceleration of the car by calculating the acceleration using the formula a = F / mass, where F is the total force acting on the car, and mass is the mass of the car. The script then iteratively calculates the velocity and position of the car using the formula v(i) = v(i-1) + a * dt and x(i) = x(i-1) + v(i) * dt, respectively. Finally, the script plots the position of the car as a function of time.

Note that this is a simple model of car acceleration and does not take into account many factors such as engine power or aerodynamics.
