What do you mean by retardation Class 7?

Retardation can be defined as the decrease in the velocity per second. Since negative acceleration is retardation, its S.I. unit is the same as acceleration. i.e., metre per second square ms−2.

What is a simple definition of acceleration?

4 days ago
acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down.

What is the SI unit of acceleration and retardation?

Si unit of retardation is same as that of acceleration as m/s2.

What is the formula of retardation?

a = Change in velocity/Time taken So, you can get a negative acceleration value in the case of v

Retardation means deceleration or the negativity to speed. The formula of retardation is V – U/ T where V is the final position U is the initial motion and T is the time taken by object. Retardation means negative acceleration.

How do you calculate velocity and acceleration?

To calculate acceleration, divide the change in velocity by the total time. Acceleration values are expressed in units of velocity per time, including meters per second squared. Acceleration is a vector quantity and is defined as the rate at which an object changes its velocity.

What is the formula for velocity and acceleration?

The formula for acceleration is given as a = (v2 – v1) / (t2 – t1), where “a” denotes the acceleration, “v2” indicates the final velocity, “v1” represents the initial velocity and “t2 – t1” is the time interval between the final and initial velocities.

What is the difference between speed and velocity and acceleration?

The difference between velocity and acceleration can be drawn clearly on the following grounds: The velocity of an object refers to the speed in a specific direction. Velocity is nothing but the rate of change of displacement. Velocity determines the speed of the moving object along with the direction of motion.
