Any push or pull which causes something to move or change its speed or direction; can be BALANCED or UNBALANCED;
A force that opposes or slows down motion; Caused by the physical contact between moving surfaces; The amount of depends upon the kinds of surfaces and the force pressing the surfaces together; Changes motion into heat.
First Law (Law of Inertia)
An object at rest stays at rest or an object in motion, stays in motion (in the same direction/at the same speed) unless acted upon by an unbalanced force
Second law (Law of Force and Acceleration)
The greater the force, the greater the acceleration, The greater the mass, the greater the force needed for the same acceleration. Calculated by: F = ma
Third law (Law of Action-Reaction)
For every action force, there is an equal and opposite reaction force. (Forces are always paired)
Negative charge; in electron cloud / orbiting around nucleus- determines reactivity of element; Almost zero mass: 1/1836 amu!
water movement on the surface of oceans caused by: Winds, Continental deflections, & the Coriolis Effect
Deep ocean currents
water movement of oceans caused by: Temperature differences, Salinity differences, and density
global conveyor belt
Movement of currents is constant and transfers heat from one part of the Earth to another via water.
