β 14y agoThe "retardation" is more correctly referred to as "acceleration".
Since the car is slowing down, the acceleration is negative.
Its average value is
(change in speed) divided by (time for the change) = (5 - 10)/2
= -2.5 m/sec2.

β 14y agoThere are three type of electrical brakes that can be applied to motors. Regenerative Plugging in Dynamic "control braking" does not mean a correct description. Dynamic braking is better.
mechanical and hydraulic are two different power transmission medium. in mechanical brakes solid links or levers are used to achieve the required braking. in hydraulic brakes there are no links, here the braking is achieved by the hydraulic fluid, the hydraulic system in which the force applied at the brake pedal is multiplied several times to achieve the requied braking.
Parachute-aided braking
resistor grids were used in DC MOTORS during dynamic braking. in this method of braking a resistance ( variable) is connected across armature winding so as to dissipiate the energy. the energy thus dissipiated is used for braking of motors.
Yes. Energy generated during regenerative braking recharges the traction battery and is later used to power the car. The Prius also has friction brakes (disk/drum), which are used at very low speeds or for hard braking. And it's braking, not breaking.
The average braking force can be calculated by dividing the change in momentum by the time taken to come to a stop. This can be expressed as (final speed - initial speed) / time. Remember to convert the speed into appropriate units before performing the calculation.
friction acting btw the road surface and wheel depends upon the braking retardation of the vehicle. every surface has its own friction coefficient which represents the maximum value , however friction can act in range from 0 to that max value , and this value depends upon the braking retardation.

Braking reduces speed.
Retardation is the application of a force that produces negative accelleration. Synonyms would be braking, decelleration, damping, etc. Gravitational force operates downward (in a negative direction) so, in most frames of reference, gravity is a retarding force.
Braking in a moving vehicle is applying the brakes to slow or halt movement, usually by depressing a pedal. The braking distance is the distance between the time the brakes are applied and the time the vehicle comes to a complete stop.
Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop.
Braking is another term used for retardation or deceleration. It refers to the process of reducing the speed or velocity of an object or vehicle.
To calculate the braking force, we need to determine the deceleration first. Using the formula: final velocity = initial velocity + (acceleration * time), we find that the deceleration is 2.5 m/s^2. Then, using the formula: force = mass * acceleration, we get a braking force of 200 N.
To calculate braking force, you can use the formula: Braking force = mass x deceleration. First, determine the mass of the object that is braking. Then, calculate the deceleration by dividing the change in velocity by the time taken to come to a stop. Finally, multiply the mass by the deceleration to find the braking force.
to balance the braking force that is applied to the energy absorbers
The average braking force can be calculated using the formula: [ \text{Average braking force} = \frac{\text{Change in momentum}}{\text{Time taken}} ] First, calculate the initial momentum of the car: ( \text{initial momentum} = 1000, \text{kg} \times 10, \text{m/s} ). Next, calculate the final momentum of the car when it comes to a stop. The change in momentum is the difference between the initial and final momentum. Finally, divide the change in momentum by the time taken to brake (5 s) to find the average braking force in newtons.
