Science: Work

Includes; Work, Force, Energy,ect.

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
