In this dynamic model the resulting force [math]F_R[/math] on an object on an inclined plane is obtained by adding the force arrows of gravitational force [math]F_G[/math] and normal force [math]F_N[/math]. Without friction, the magnitude of the resulting force on a cart can be measured depending on the angle of inclination [math]\alpha[/math] using a force meter. [br]To confirm the concept of adding forces, the mass of the cart [math]m[/math] and the angle of inclination must be set in the model corresponding to your setup. Compare results several times by varying mass and angle.
