To the stationary observer the ball follows a straight-line path, so there is no problem squaring this trajectory with zero net force.

So straight-line (geodesic) paths have a much higher probability in the sum-over-histones.

The straight-line path is therefore the longest path in Minkowski space.

To travel through a shortcut, you set a straight-line path toward the point at the center of the sphere.

That air build-up on one side causes an increase in pressure, and that's what forces the ball away from a straight-line path.

She drew bright, straight-line paths across the starmap with her fingertip.

Declines don't follow a straight-line path.

Small gas bursts altered its straight-line path to curve around the close horizon.

Gravity causes the dart to fall away from this straight-line path, making a trajectory that is in fact a parabola.

Practical rangekeepers had to assume that targets were moving in a straight-line path at a constant speed, to keep complexity to acceptable limits.
