Why do physical objects move? by Julia Frankowicz III A
Bodies move towards each other.
The smooth surface, in contrast to the hard one, makes it easier for an object to move…
In physics, force is defined as the rate of change of the momentum of the body.
Experiment with air-cushion
Experiment with glass vacuum tube.
Force is an influence that causes an object to accelerate. In this case, the sum of all forces acting on the body caused its rotation.
The Principle of Inertia is a fundamental principle of classical physics.
