Term | Definition |
---|---|
System | A group of individual parts or procedures that work together to accomplish a desired task. |
Components | All the different parts of a system. |
Work | the amount of effort spent when a force causes an object to move a distance. |
Force | A push or pull that acts on an object. |
Contact Force | forces that must touch the object that they push or pull. |
Friction | A force that opposes the relative motion of an object. |
Mass | The amount of matter in an object. |
Weight | The amount of force on an object due to gravity. |
Mechanical System | A group of physical parts that interact with each other. |
Energy | the ability to do work. |
Kinetic Energy | Then energy when an object moves |
Potential Energy | When an object stores its energy to do work later. |
Gravitational Potential Energy | The potential energy of an object that is able to fall |
Gravity | Is the attraction between two objects due to their mass. The amount of attraction depends upon the amount of each object’s mass and the distance between the two objects. |
Mechanical Advantage | The amount by which a machine can multiply an input force |
Ideal Mechanical Advantage | The mechanical advantage of a machine that has no friction |
Action-at-Distance | Forces that push or pull an object without touching it. Gravity, static electricity, and magnetism produce action-at-a-distance forces. |
Spring Scale | It can measure forces other than weight |
Machine | is any mechanical system that reduces the force required to accomplish work |
Input Force | The force that is applied to the machine |
Output Force | The force that the machine applies to the object |
