Volume, Density, Torque and Impulse

Volume, Density, Torque and Impulse
A body’s volume is the amount of space that it occupies. Density
combines the mass of a body with the body volume. Density is defined
as mass per unit of volume. A rotary effect created by an eccentric force
is known as torque or moment of force. Torque, which may be thought
of as rotary force, is the angular equivalent of linear force. Impulse is
defined as product of force and the time over which the force acts.

Centre of Gravity, Weight and Pressure

Centre of Gravity, Weight and Pressure
A body’s centre of gravity, or centre of mass, is the point around which
the body’s weight is equally balanced, no matter how the body is
positioned. Weight is defined as the amount of gravitational force
exerted on a body. Pressure is defined as force distributed over a given
area.

Inertia, Mass and Force

Inertia, Mass and Force
Inertia means resistance to action or to change. Inertia is the tendency
of a body to maintain its current state of motion, whether motionless or
moving with a constant velocity. Mass is the quantity of matter
composing a body. Force can be thought of as a push or a pull on a
body. Each force is characterised by its magnitude, direction, and point
of application to a given body.
