[Free Registration/Login Required] Learn about the relationship between position and velocity for a diver accelerating under the influence of gravity and air resistance. Measure velocity and position based on variables of the height of...

Animated simulation re-enacts Galileo's experiment of dropping objects off the Leaning Tower of Pisa.

This site provides a very interesting overview of our home planet, Earth. Content includes a focus on the atmosphere, the pull of gravity, and the active surface.

Article outlining the scientific history behind the evolution of theories about measuring time based on the movement of a pendulum, and about how gravity would impact a pendulum's movement depending on one's proximity to the Earth's...

This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, but you'll be taking advantage of modern video recording technology to make your measurements. The...

Background information on vectors and their use in describing motion in two dimensions. A comparison of Aristotle's and Galileo's perspectives on force and motion is given.

This site from NASA compares free falling motion to falling with air resistance. Discusses Galileo's experiment. Explains why we believe all objects free fall with the same acceleration.

Try this at-home science experiment to learn about acceleration due to gravity.

Design a catapult, blast a balloon into the air, and try to hit the target the first time. If you miss, adjust the velocity and angle to reach the desired trajectory.

In this document, we will try to answer a fundamental question of physical science, "Why do things start to move, slow down, speed up, stop moving or change direction?" In answering these core questions we can develop concepts that can...

A short account of Newton's life is provided (from birth to death) as is a somewhat detailed look at Newton's studies of gravity.

This site provides instructions for a demonstration illustrating the "mystical force called gravity that pulls everything on Earth downward."

A page describing rotational equilibrium and non-equilibrium situations. Includes graphics, equations, and many examples.
