FORCE, WORK AND ENERGY POWER



FORCES Force is all that can to deform a body or change its state of rest or motion.
forces are represented by arrows indicating the direction and sense of force. They can also indicate its intensity. ACTIVITY

FORCES TYPES OF FORCES

According mode of action:

• Forces acting on contact: those that are applied directly on the body. • Remote
Forces are those which act from afar, as the electromagnetic force or gravity. According

duration:

• Shadow Forces operating a very short timespan. Cause a movement with constant velocity (constant)
• constant forces are operating continuously and produce a uniformly accelerated motion.

Unit:

The unit of force is the Newton in the international system of measures. Is the force with which the earth attracts an object of 102 g.



WEIGHT The weight of a body is the attractive force of gravity exerted on it.
Weight depends on the object's mass and gravity P = mG where G is the acceleration of gravity.
units is measured in weight is the Newton (N) and kilopond, which is the force with which the earth attracts an object of 1 kg of mass (Kp). 1kp = 9.8 N.
"ACTIVITIES ON THE WEIGHT"


THE PUSH

According to Archimedes' principle of a body immersed in a fluid experiences an upthrust equal to the weight of the fluid volume it displaces. E = VDG



Relationship object and fluid densities and fluid weight and push the subject.

EFFECTS OF FORCES

Upon movement

when forces acting on an object produce a change in its state of rest or motion.

When an object is moving and he does not act any forces the object continues with a uniform rectilinear motion.

When a force acts continuously on a body produces in him a uniformly accelerated motion. The expression of this effect: F = m

. to
a = F / m
m = F / a

The video can be seen as the astronaut moves when driving. If it were not attached by a cord to the ship, take an indefinite break it with a uniform linear motion.

ON THE DEFORMATION OF BODIES

solids can behave with respect to a force deformable or deformable solids.

deformable solids: They can be plastics if you do not recover their initial shape after a force acted on them or elastic if they recover their original shape.

non-deformable solids: they are not deformed by a force acting on them. If the force is greater than the resistance offered, the solid breaks.

FORCE, WORK AND ENERGY

job displacement is called suffered by a body when a force acts on it.

W = F. d

measurement unit or the work is July. July 1 is the displacement of a body 1 m on which it is applied a force of 1 N.

Energy is the ability of bodies to perform work. The unit of measurement is the joule.

A type of energy is mechanical energy. Kinetics distinguish due to the movement and the potential due to the altitude. A special type of potential energy is the stored elastic potential deforming elastic materials.
