refers to the size or strength of the force
magnitude
direction
point of application
line of action
– points to where the object goes.
point of application
line of action
direction
magnitude
the location of where the force is applied.
point of application
line of action
direction
magnitude
– forces where objects touch or contact with each other
contact forces
friction
normal
– is the force acting against or opposite an object in contact with
which makes the movement of the object slow down.
normal
friction
applied
contact forces
is the force that acts perpendicular to the surface of the object in
contact with
normal
friction
applied
– is the force applied to an object.
tension
gravitational
noncontact forces
forces where objects do not touch or contact with each other.
contact forces
non contact forces
magnetic
is the force of attraction between two objects.
gravitational
magnetic
balance forces
are forces exerted on a field of attraction or repulsion as in the
case of magnets and other magnetic materials.
magnetic
balance forces
non balance forces
Forces that are equal in magnitude but opposite in direction are called
unbalanced forces
friction
gravity
balance forces
Forces that cause a change in the motion of an object are
net force
unbalance forces
balance forces
e is the sum of all forces acting on an object.
resultant force
gravity
flexibility
what is the first law of motion?
gravitational force
law of interaction
law of inertia
law of acceleration
what is the second law of motion
law of inertia
law of acceleration
law of interaction
what is the third law of motion
law of acceleration
law of inertia
law of interaction
The tendency of an object to maintain its
state of rest or of uniform velocity in a straight line is called
interaction
inertia
acceleration
speed
The energy that the body gains or losses with respect
to its position is called
potential energy
kinetic energy
gravitational energy
magnetic energy
The energy of a moving object is called
kinetic energy
gravitational energy
potential energy
magnetic energy
other name for kinetic energy
energy of speed
energy of motion
energy of attraction
is the ability of a material to return to its original form after a
certain amount of force has been applied to it.
elasticity
malleability
sound wave
solidify
is an intrinsic property that is determined by the amount of mass
per area of space or volume of the material.
elasticity
density
temperature
vibration
usually described as the turning back of the wave as it hits a barrier.
reflection
reverberation
echo sounding
refers to multiple
reflections or echoes in a certain place.
reverberation
echo sounding
sound reflection
This is used by
scientists to map the seafloor and to determine the depth of the ocean or sea.
echo sounding
reverberation
vibration
is a kind of
refraction which provided us colors of light. This phenomenon is observed when
white light passes through a prism.
dispersion
prism
frequency
is a transparent optical element with flat and polished surfaces that
disperses light.
prism
dispersion
spectrum
the SI unit of heat
Joule
celsius
fahrenheit
introduced the third
temperature scale which is called kelvin.

is the rate of flow of electric charges from one point to
another in a circuit.
electric current
frequency
coulomb
Electric current is measured by
Amperes

what is the standard unit of electric charge
coulomb
amperes
power
The work needed
per unit charge to move between two points is called
voltage
amperes
coulomb
is the opposition to the flow of current by the
conducting wire.
electrical resistance
conduction
convection
current resistant
A closed loop through which current can flow is called
electric circuit
wires
connectors
transformers
is a device that maintains a constant amount of voltage.
Common voltage sources used at home are battery, generator, wall socket, and
electric outlet
