Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Acceleration is
A
increasing speed
B
decreasing speed
C
changing direction
D
all of the above
Explanation: 

Detailed explanation-1: -Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction-or change both.

Detailed explanation-2: -Acceleration (a) is the change in velocity (v) over the change in time (t), represented by the equation a = v/t. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).

Detailed explanation-3: -Mainly, Uniform acceleration, non-uniform acceleration, and average acceleration are the three types of accelerated motions. The term uniform acceleration refers to a motion wherein an object travels in a straight line with an increase in velocity at equal intervals of time.
