Measurement is the process of finding the length, size, or quantity of a substance. ... A physical quantity (like length) has to be measured with respect to some fixed quantity. A fixed quantity with respect to which a physical quantity is measured is called a unit. A unit is used as a standard of measurement.
The consequent acceleration, in, is caused by doubling the net force, F, acting on the same object.ms^-2 is going to 2a.
What is net force?
The vector sum of the forces exerted on a particle or body is known as the net force. As with all actual forces combined, its corresponding torque, or net force, forms the resultant force and affects the object's rotational motion. A torque-free resultant force may be defined by a system of forces.
