Define retardation and give an example of a body having this motion.
Answers
Answer:
The negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative. Retardation is the rate of decrease in velocity. For example - A car stopping in front of a red light
Answer:
A force is any physical force that changes (or tends to change) the size, shape, or state of rest or motion of the body.
Explanation:
Explanation
Retardation is the opposite of acceleration. The body's velocity can either increase or decrease. Acceleration is the measurement of a change in velocity. Acceleration is said to be positive when the body's velocity increases. The acceleration is also said to be negative if the velocity decreases.
The train slows as it approaches the station; in this case, we can say the train is retarding. Acceleration with a negative sign is referred to as retardation. Alternatively, a negative acceleration value indicates that a body's velocity is decreasing.
Final answer
The term "retardation" refers to a body's velocity decreasing over time. A negative acceleration is retardation. A train approaching a station, for example, must be retarded in order to stop.
Hope this answer helps then pls mark me as brainlist
