Science

• ENERGY - is very important in doing work.
• BALANCE - is very essential in the field of sports such as basketball, swimming, badminton and boxing.
• STATIC - is a branch of mechanics that deals with the study of objects at rest or in static equilibrium.
• FORCE WEIGHT FW - the force acting on the body, which is the weight of the body.
• NORMAL FORCE FX - which is upward reaction force exerted by the table.
• STATIC EQUILIBRIUM - it is a condition in which all forces acting on the body are balanced.
• CENTER OF GRAVITY - an object is the point at which the weight is evenly dispered and all sides are in balanced.
• BALANCING METHOD - the method used in determining the center of gravity.
• GEOMETRICAL METHOD - the center of gravity for regular bodies such as spheres, cubes, cylinders, and ring is determined using the method.
• PLUMB LINE METHOD - is used to determine the center of gravity for irregular-shaped bodies.
• STATES OF EQUILIBRIUM - if we want the object at rest to be stable, we have to consider its condition for the object not to slip or tilt easily.
• STABLE EQULIBRIUM - means that, with small displacement of the body from the state, forces or moments of forces emerge which tend to return the body to its original position.
• UNSTABLE EQUILIBRIUM -means that, with a small displacement of the body from its original position, force emerge which tends to caused the object to move to a different position.
• NEUTRAL EQULIBRIUM - even with small displacement, the body remains in equilibrium.
• DISADVANTAGES OF TAKING DOWN THE CENTER OF GRAVITY OF THE VEHICLE

  • INCREASED BOTTOMING OUT
  • UNEVENESS IN THE TIRE WEAR
  • CONFLICT WITH OTHER SYSTEMS AND COMPONENTS
• MMDA - Metropolitan Manila Development Authority
• normal fault -the block above the fault moves down relative to the block below the fault.
• reverse fault - the block above the fault moves up relative to the block below the fault
• strike-slip fault - the movement of the blocks along a fault is horizontal.
• left lateral - the block on the far side of the fault moves to the left.
• right lateral - the direction of the movement is rightward.
• big one - is an earthquake expected to occur with a magnitude of 7.2 or stronger.
• focus or hypocenter - the phase within the earth where the rock first breaks and sends out earthquake a seismic waves
• seismic waves - are shock waves created at the hypocenter of the earthquake
• epicenter - the point on the ground's surface directly above the focus.
• earthquake - the shaking or trembling of the earth caused bby the pieces of the crust of the earth that suddenly shifted.
• trench - the deep depression in the ocean basin.
• subduction - the process when two oceanic plates collide, the denser plates dives under the other.
• divergent boundary - occurs when adjacent tectonic plates move away from each other.
• transform boundary - where the two plates slide against each other in a side ways motion.
• covergent boundary - when two plates move toward each other.
• plate boundaries - are found at the edge of the lithospheric plates
• thermal convection - the transfer of heat through fluid motion.
• mantle - the thick, mostly solid layer of the earth between the crust and the core.
• ridge push - a force that comes from the heat expelled by the magma that expands the lithosphere and asthenosphere
• slab pull - the force that sinking edge of the plate exerts on the rest of the plate
• plate boundary volcanoes - most of the world's active volcanoes are located along
• Alfred Wegener - a german meteorologist who proposed the Theory of Continental Drift
• Harry H. Hess - He proposed the seafloor spreading
• 1912 - the year when the theory of continental drift proposed
