Define velocity in science

Webmass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force. The unit of mass in the International System of Units (SI) is the … Webvelocity. ( vɪˈlɒsɪtɪ) n, pl -ties. 1. speed of motion, action, or operation; rapidity; swiftness. 2. (Units) physics a measure of the rate of motion of a body expressed as the rate of change of its position in a particular direction with time. It is measured in metres per second, miles per hour, etc. Symbol: u, v or w.
