a rate of motion determined by dividing the total distance traveled by the total travel time
the steepness of a line on a graph, equal to its vertical change divided by its horizontal change
the study of large scale movement and deformation of the earth's outer layers in terms of rigid plates over a partly molten layer of the upper mantle
The overall force on an object when all the individual forces acting on it are added together
the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
conservation of momentum
Momentum of a system remains constant when there are no net external forces acting on it.
a continuous amorphous substance that tends to flow and to conform to the outline of its container: a liquid or a gas
the buoyant force on an object is equal to the weight of the fluid displaced by the object
a system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area
any mechanical or electrical device that transmits or modifies energy to perform or assist in the performance of human tasks

the amount of heat required to raise the temperature of 1g of a substance 1 degree Celsius
a device that uses outside energy source to transfer thermal energy from a cool area to a warm area
an instrument for showing directions, consisting of a needle or compass card that points to the north magnetic pole, which is near the North Pole.
continuous stream of high-energy particles released into space in all direction from the sun's corona
the region around a charged object where the object's electric force interacts with other charged objects
A source of stored chemical energy for electric currents, having a positive (+) and a negative (-) terminal.
