Question

define acceleration.​

Answer 1

$\large\sf{Answer:}$

• Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Answer 2

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. ... Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

Some good examples of acceleration related to daily life are:

When the car is speeding up.

When the car slows down.

When you fall off a bridge.

The car turning at the corner is an example of acceleration because the direction is changing. The quicker the turns, the greater the acceleration.
