Question: What Is The Retardation Of The Body?

Which quantity is retardation?

Retardation, or negative acceleration, having both magnitude and direction, is a vector quantity..

What is non uniform retardation?

non uniform retardation means when there is deacceleration in unequal time intervals…..

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).

Can an object moving in a certain direction with an acceleration in the perpendicular direction?

(b) an object moving in a certain direction with acceleration in the perpendicular direction. Answer: … The object can move in a certain path with a perpendicular acceleration, in the case of circular motion.

What is retardation example?

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. (

How do you find retardation?

∴ retardation =tu−v=1025−0ms−2=2. 5 ms−2.

What is the dimensional formula of retardation?

Answer. a= u – v/t it is formula of retardation.

How do you calculate angular retardation?

To calculate retardation use the standard formula V = U + at. Since V is lesser than U , the answer you get will be negative and hence “a “will be retardation. To calculate velocity change of displacement with respect to time.

In which condition retardation is possible?

If your child has an intellectual disability (ID), their brain hasn’t developed properly or has been injured in some way. Their brain may also not function within the normal range of both intellectual and adaptive functioning. In the past, medical professionals called this condition “mental retardation.”

What is retardation acceleration?

Retardation is just the opposite of acceleration or the decrease of velocity per unit of time. Acceleration can be positive(+),0,or negative(-). Negative of acceleration is known as retardation. Negative Acceleration is called Retardation, or Deceleration.

What is retardation Class 11?

Answer Verified. Hint: Retardation is another name for deceleration. Deceleration is a vector quantity that can act on a moving body such that it reduces the magnitude of the velocity (speed) of the body. So, we can say that deceleration is an acceleration that is directed opposite to the velocity vector of a body.

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.

How do you get uniform retardation?

Answer: 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

How do you find time?

To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.

What is the example of uniform velocity?

Uniform velocity: Covering Equal distance in equal interval of time. E.g: Rotational speed of Earth. Non – uniform velocity: Covering unequal distances in unequal interval of time. E.g: Driving a car in a traffic lane.

What is retardation and how does it affect the speed?

Retardation is the acceleration which acts opposite to the direction of the motion of the body which causes decrease in the velocity of the moving body. Thus it slows down the moving body. Acceleration is defined as change in velocity.

Is retardation positive or negative?

Retardation is nothing but a negative acceleration. The velocity of the body may either increase or decrease. The change in velocity is known as acceleration. If the velocity of the body increases, acceleration is said to be positive.

Is retardation and acceleration the same?

Acceleration of a body is defined as the rate of change of its velocity with time. … Retardation means negative acceleration. If the velocity of a body decreases,the acceleration is negative.

What is uniform retardation?

A body with uniform retardation means that it is decreasing , as retard means to reduce or decrease , at a constant rate with respect to time. Retardation is depicted by a negative slope and a negative value of acceleration, overall it’s just opposite of acceleration.

What is positive acceleration?

When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.
