Forces are interactions that cause changes in motion from "summary" of Physics 11 by British Columbia. Schools Department. Curriculum Development Branch
Forces play a crucial role in the world of physics. They are interactions that can lead to changes in an object's motion. This means that forces can cause objects to speed up, slow down, change direction, or even remain at rest. In essence, forces are what make things move. When discussing forces, it is important to understand that they can come in different forms. For example, there are contact forces, such as friction or tension, which occur when two objects are in direct physical contact with each other. On the other hand, there are also non-contact forces, such as gravity or magnetic forces, which can act on objects without any physical contact. Furthermore, forces are typically described using a set of specific characteristics. These include the direction in which the force acts, the magnitude or strength of the force, and the point of application of the force. By considering these characteristics, we can better understand how forces interact with objects and cause changes in their motion. One important concept related to forces is Newton's Laws of Motion. These laws provide a framework for understanding how forces influence the motion of objects. For example, Newton's First Law states that an object will remain at rest or in uniform motion unless acted upon by an external force. This law highlights the idea that forces are necessary to change an object's state of motion.- Forces are essential components in the study of physics. They are interactions that can lead to changes in an object's motion, whether it be speeding up, slowing down, changing direction, or remaining at rest. By considering the different forms of forces, their characteristics, and Newton's Laws of Motion, we can gain a deeper understanding of how forces shape the world around us.
