11 Questions
What is the primary function of a physical system?
To perform a specific function using physical parts
What is the main difference between a physical system and a social system?
Physical systems rely on physical parts, while social systems are made up of people or living things
What is the purpose of components in a system?
Components are the parts required by the system to perform a specific function
What is an example of a system that is often overlooked?
A social system, such as a group of people working together
What is the ultimate goal of a system, regardless of its type?
To perform a specific task or function
Describe the key difference between contact forces and action-at-a-distance forces.
Contact forces must touch the object that they push or pull, whereas action-at-a-distance forces can push or pull an object without touching it.
Explain the concept of friction and its effect on the motion of an object.
Friction is a force that opposes the relative motion of an object, causing it to slow down or stop. It depends on the surface and object properties.
What is the force of gravity, and how does it depend on the mass of objects and the distance between them?
Gravity is the attraction between two objects due to their mass, and its strength depends on the mass of each object and the distance between them.
How does the force of gravity (Fg) on an object near the surface of Earth depend on its mass, and what is the unit of measurement?
Fg = mg, where m is the mass of the object in kg, and g is the acceleration due to gravity (9.8 N/kg) on Earth.
What is the weight of a 50 kg student on Earth, and how is it calculated?
The weight of a 50 kg student on Earth is 490 N, calculated using Fg = mg = 50 kg x 9.8 N/kg.
Provide an example of a contact force and an action-at-a-distance force, and explain how they differ.
Hitting a baseball with a bat (contact force) versus the attraction between two objects due to gravity (action-at-a-distance force). The key difference is that contact forces require physical touch, while action-at-a-distance forces do not.
