The document summarizes key concepts in physics including work, kinetic energy, potential energy, power, and simple machines. It defines these terms and provides the relevant equations. For simple machines, it describes the inclined plane, wedge, screw, lever, pulley, and wheel and axle - outlining what each is and how it functions.

3. WORK

4. WORK
 Product of the force applied to a body and the
displacement of the body in the direction of the applied
force.

5. In symbols:
where:
W = work
F = force
d = displacement

6.  If the force applied makes an angle with the direction of
motion, the equation used is:
where:
θ = is the angle
between F and d

8. KINETIC ENERGY
 Is the energy in motion
In symbols:
where:
KE= kinetic energy
m= mass
v= velocity

9. POTENTIAL ENERGY
Is the stored energy of position

10. GRAVITATIONAL POTENTIAL ENERGY
 The potential energy of a body as a result of its vertical
displacement
In symbols:
GPE = mgh
Where:
m= mass
g= is the acceleration due to gravity
h= height

11. POWER

12. POWER
 Power is the rate at which energy is
transferred, used, or transformed.
In symbols:
where:
P = power
W= work
t = ocity

13. SIMPLE
MACHINES

14. SIMPLE MACHINES
 Is a mechanical device that multiplies, and
changes the direction or magnitude of a force. In
general, they can be defined as the simplest
mechanisms that provide mechanical advantage.

15.  These simple machines fall into two classes: (I.) the
inclined plane, wedge, screw characterized by
the vector resolution of forces and movement along
a line, and (II.) the lever, pulley, and wheel and axle
are characterized by the equilibrium of torques and
movement around a pivot.

16. INCLINED PLANE
 An inclined plane is a straight ramp and is used for
moving loads up and down the hill
 It is a flat surface that lies at an angle relative to
level ground used to form a ramp to raise and lower
a load.

18. WEDGE
 A wedge is a triangular shaped round tool and is
used to separate two objects or portions of an
object, lift an object, or hold an object in place.
 It functions by converting a force applied to its blunt
end into forces perpendicular (normal) to its inclined
surfaces

20. SCREW
 A screw is a mechanism that
converts rotational motion to linear motion, and
a torque (rotational force) to a linear force.
 The most common form consists of a cylindrical
shaft with helical grooves or ridges
called threads around the outside.

22. LEVER
 A lever is constructed from a beam attached to
ground by a hinge, or fulcrum.
 A lever amplifies an input force to provide a greater
output force, which is said to provide leverage.

24. PULLEY
 A pulley is a wheel on an axle that is designed to
support movement of a cable or belt along its
circumference. Pulleys are used in a variety of
ways to lift loads, apply forces, and to transmit
power.

26. WHEEL AND AXLE
 A wheel and axle is a simple machine made up of
two circular objects of different size. The axle (a
small wheel) is attached to the center of a larger
wheel. All wheels need an axle. The wheel and axle
must move together to be a simple machine. A
wheel and axle lifts or moves loads.
