A
newton
is defined as the amount of force required to
accelerate
an object with mass equal to one kilogram at a rate of one meter per second squared.
The SI unit of force is the
Newton
(N).
Force can be calculated using
F = ma
, where m is the
mass
of the object being acted upon by the force and a is its acceleration.
The SI unit of pressure is
Pascal
(
Pa
).
Pressure can be calculated using the formula P = F/A, where P is
pressure
, F is
force
, and A is area.
Newtons
are used to measure
forces
that act on objects.
Atmospheric
pressure is measured by
barometers.
Forces acting on an object cause it to change
direction
or
speed.
Pressure
is defined as the
ratio
between the applied force on a surface and that surface's area.
Newtons are used to measure
forces
, while pascals are used to measure
pressures.
Pascals
are used to measure
pressures
acting on surfaces.
An example of a situation involving both force and
pressure
is when a
balloon
is inflated with air or gas.
In physics, there are two types of motion -
translational
motion and
rotational
motion.
There are two types of forces -
contact
forces and
non-contact
forces.
An example of a situation involving both force and
pressure
is when a
balloon
is inflated with air or gas.
Forces have both
magnitude
and direction, while pressures only have
magnitude.
When a balloon is filled with
air
, it exerts a force on the walls of the container due to the
pressure
inside the balloon.
Friction is a type of contact force that
opposes motion
between two surfaces.
Absolute
pressure refers to the total amount of pressure acting on an object, including both gauge and
atmospheric
pressures.
Kinetic friction
occurs when one surface moves over another.
Static friction occurs when there is no relative
movement
between two surfaces.
Gauge pressure
measures how much air or gas is inside an enclosed space compared to
atmospheric pressure.
Boyle's Law states that at constant temperature, the volume of a given mass of confined gas varies
inversely
with the
absolute
pressure applied to it.
Force
is defined as the product of mass times
acceleration.
Gravity
is defined as the
attractive
force exerted by one body upon another due to their masses.
Weight is defined as the
gravitational
pull on an object with
mass.
