The rise of Galileo and his fall from grace. Copernicus conjectured that the Earth spins on its axis and orbits around the sun. Considering its implications, a rather dangerous assumption that prompted rather risky questions: Why do objects fall to Earth rather than hurtle off into space? And in this heretical scheme of things in which the Earth wasn't at the center, where was God? Risking more than his favored status in Rome, Galileo helped to answer such questions with the law of inertia.

Join Nanna in her mad lab as she demonstrated and explains inertia. Inertia, simply put, is changing the speed and direction of an object. Nana uses a large jar, plastic plate, cardboard box and a bar of soap in her demonstration. Run time 05:27

If you spin a raw egg and then stop it, it will start spinning again without you having to touch it. A boiled egg, on the other hand, stops and doesnt' move. This short video is a good explanation of the concept of inertia (01:10).

This NASA video segment explores how Newton's first law of motion applies to aerospace. An instructor at NASA's National Test Pilot School defines the law of inertia and then explains how the seatbelt in a jet provides an outside force to stop the inertia of the pilot. The instructor also discusses inertia experienced by humans while riding in the test vehicles for space travel (03:24).

Inertia refers to resistance to change or movement, so that
the bigger the inertia, the bigger the force needed to be applied to the
object. Lear more about inertia as a resistance to changes of movement with information from a science teacher in this video.

Gravitational force is the constant force of attraction between the masses of two objects. The attraction between all objects and the Earth is called gravity. Weight is caused by gravity: it is the measurement of gravity's force (or pull) on an object's mass. Learn more about gravity with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.

Anytime there is a change in motion, force is the responsible party. It has to overcome inertia to act on an object. Inertia keeps an object either sitting still or moving at a constant speed. Learn more about force and motion with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.

This video shows the three laws of motion developed by Sir Isaac Newton and is done with excellent graphics.
The first law of motion, inertia, is when an object will not move or else move in a straight line unless an unbalanced force acts on it. The second law of motion states that force is the product of mass and acceleration; acceleration fo an object depends on the mass and magnitude of the force. (force=massxacceleration) The third law of motion is the law of action and reaction. In every action there is an equal and opposite action such as in rockets (04:24).

Inertia means that an object in motion will stay in motion in the same direction, or will stay at rest, unless another force acts upon it. For an object to change direction or stop moving, something has to overcome inertia. Learn more about inertia with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.
