ENERGY- Is the ability to do work. WORK - Is performed when a force is applied through a distance You can tell something has moved when it has changed _POSITION_. To calculate speed, you must know _TIME_ and _DISTANCE_. FRICTION_ -A force between objects that slows an object down. ACCELERATION_ -A change in speed or direction. INERTIA_ -A tendency to stay at rest or in motion until an outside force acts upon an object. FORCE__ -Any push or pull that causes and object to move. GRAVITY_ Pull between two objects. WEIGHT_ Measure of gravity In order to describe velocity, you need to know _SPEED_ and _DIRECTION_. The six types of simple machines are: _SCREW, LEVER, WHEEL AND AXLE, WEDGE, INCLINED PLANE, PULLEY_ MACHINE_- Anything that makes work easier. LOAD_ - Object being moved by a machine. EFFORT_ How much force you use to move something. NEWTON_ - Unit used to measure force. Forces used in a simple machine are _PUSH_ and _PULL_. FRICTION_ Force that slows motion The six forms of energy are: _ELECTRICAL, THERMAL, CHEMICAL, MECHANICAL, LIGHT, SOUND_ POTENTIAL_ energy is stored energy. KINETIC_ Energy of motion Forces that are equal in size and are opposite in direction are called BALANCED FORCES_.
