Poetry uses forms and conventions to suggest differential interpretation to words, or to evoke emotive responses. Devices such as assonance, alliteration, onomatopoeia and rhythm are sometimes used to achieve musical or incantatory effects.
The average speed of an object tells you the (average) rate at which it covers distance. If a car's average speed is 65 miles per hour, this means that the car's position will change (on the average) by 65 miles each hour.
Speed is the distance an object travels per unit of time. Speed can be expressed as kilometers per hour (km/hr), meters per second (m/s), and so on. In most cases, objects donât travel at a constant speed. Therefore, the average speed is used to describe the motion. s = speed, t = time, and d = distance. Acceleration is the rate at which an objectâs speed changes. Acceleration can be expressed as meters per second per second (m/s/s or m/s2). Forces such as gravity, air resistance, and friction can cause an object to decelerate (decrease speed over time).
