The concept of forces was understood by ancient civilizations, but the modern scientific study of forces is often attributed to Sir Isaac newton, particularly through his laws of motion. Newton's work laid the foundation for our understanding of the role forces play in the physical world.
Henri Becquerel was the first to discover radiation in 1896 while he was studying phosphorescent materials.
When running downhill, the main forces acting on a person are gravity, which propels the person downward, and air resistance, which opposes the person's forward motion. The person's muscles contract to control their speed and maintain balance.
The person will remain stationary because the forces cancel each other out, resulting in no net force on the person.
When a person sits in a chair, the main forces acting on them are the gravitational force pulling them downward towards the Earth and the normal force exerted by the chair pushing them upward to counteract gravity. Frictional forces between the person and the chair also play a role in keeping them seated comfortably.
Isaac Newton is credited with being the first scientist to discover that white light is actually composed of a spectrum of colors. He achieved this by passing white light through a prism, which separated it into its component colors, creating a rainbow spectrum.
