Retardation is the decrease in velocity per second.

Its SI unit is metre/second2 (m/s2)..

What is retardation give example?

Negative acceleration is called ‘retardation’ or ‘deceleration’. For example, when a stone is thrown upwards, it is under retardation. Similarly, when a bus approaches a bus-stop, its motion gets retarded. In both the cases mentioned above the acceleration decreases.

How do you find retardation?

So formula will be the same as that of acceleration. Where v = final velocity, u= initial velocity & t= time taken to change the velocities. So in case of v

What is deceleration formula?

The Formula for Deceleration It is denoted by –a, where a is acceleration. If starting velocity, final velocity and time taken are given, then Deceleration Formula is given by, a = v − u t \frac{v-u}{t} tv−u.

What is the SL unit of retardation?

Retardation means change in velocity per unit time is negative . e.g retardation is also a acceleration but negative sign . hence, si unit of retardation is equal to Si unit of acceleration . SI of retardation = m/s²

What is the retardation?

Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.

What is the SI unit of deceleration?

SI unit of deceleration is m/s2. … An object moving with a velocity of 40m/s is brought to rest in 8 seconds by a constant deceleration.

What is the example of uniform retardation?

Example of uniform retardation: If a car moving with a velocity ‘v’ is brought to rest by applying brakes, then such a motion is an example of uniform retardation.

What is unit of speed?

The speed of an object is how far the object travels in one unit of time. The formula for speed is: speed = distance time. The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph).

What is the example of uniform acceleration?

One of the common examples of uniformly accelerated motion is freely falling bodies. The only acceleration which is acting on the body is g (acceleration due to gravity).
