Check all that apply: C] With the larger time interval it would be important to consider relativistic effects. O The distance moved in the short time interval is small compared to the distance from the star to the planet, so the force is neariy constant in the momentum update equation. C] The momentum change in the short time interval is small compared to the momentum, so the velocity in the position update equation is nearly constant. ____________________________________________________________________ C
