In this and the next activities, we will study why and how objects move.
Describing moving objects mathematically was done a long time ago by the
famous natural philosopher, Isaac Newton, who based some of his studies on
the works of Galileo Galilei, another natural philosopher. (Nowadays, we
refer to the natural philosophers as scientists.)
Newton discovered three laws followed by moving objects. We will take
up these laws one by one.

Newton’s First Law of Motion: The Law of Inertia
An object that is at rest will not move unless an unbalanced force
acts on it. An object that is in uniform motion will tend to remain in such
motion unless an unbalanced force acts on it.
Application:
1. When riding in a moving vehicle and it suddenly stops, the passengers feel
themselves bending forward as if continuing with the motion. Draw an
illustration of this situation.
2. Tell what will happen to a rolling ball on the floor if the floor is infinitely
smooth, there is no wall, and nobody stops the ball.
