inclined plane

The authors released a heap of the seeds down an inclined plane while a camera recorded their descent to analyze their speed and the dynamics of their movement.

But Galileo saw a deeper truth in the inclined plane experiments.

Lift with some danged pulley system involving fulcrums and levers and inclined planes, or, better yet, just hire some dumb lunk.

His observations of a swinging pendulum, and of balls rolling down inclined planes, are classic examples.

Some were the remains of an inclined plane, or funicular, which was built where a slope was too steep for the early locomotives to travel up and down safely.
