‘The outbreak of World War II in 1939 gave a new impetus to receiver development.’;

Momentumnoun

(physics) (of a body in motion) The tendency of a body to maintain its inertial motion; the product of its mass and velocity.

Impetusnoun

A force, either internal or external, that impels; an impulse.

Momentumnoun

The impetus, either of a body in motion, or of an idea or course of events. (i.e: a moment)

Impetusnoun

The force or energy associated with a moving body; a stimulus.

Momentumnoun

The quantity of motion in a moving body, being always proportioned to the quantity of matter multiplied by the velocity; impetus.

Impetusnoun

An activity in response to a stimulus.

Momentumnoun

Essential element, or constituent element.

Impetusnoun

A property possessed by a moving body in virtue of its weight and its motion; the force with which any body is driven or impelled; momentum.

Momentumnoun

A property of an activity or course of events, viewed as analogous to forward motion or to physical momentum (def. 1), such that the activity is believed to be able to continue moving forward without further application of force or effort; - often used to describe an increase in the acquisition of public support for a purpose; as, as, the petition drive gained momentum when it was mentioned in the newspapers.

Impetusnoun

Momentumnoun

an impelling force or strength;

‘the car's momentum carried it off the road’;

Impetusnoun

The altitude through which a heavy body must fall to acquire a velocity equal to that with which a ball is discharged from a piece.

Momentumnoun

the product of a body's mass and its velocity;

‘the momentum of the particles was deduced from meteoritic velocities’;

Impetusnoun

a force that moves something along

Momentum

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta) is the product of the mass and velocity of an object.

Impetusnoun

the act of applying force suddenly;

‘the impulse knocked him over’;
