Question

Define a) speed b) momentum c) 1 dyne​

Answer 1

Answer:

a) Speed: Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.

b) Momentum: Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.

c) 1 dyne: Dyne, unit of force in the centimetre-gram-second system of physical units, equal to the force that would give a free mass of one gram an acceleration of one centimetre per second per second. One dyne equals 0.00001 newton.
