No. It is the change in velocity (not speed) during a given interval of time. It can be an increase or a decrease although a decrease is also called a deceleration.
The distinction between velocity and speed can best be illustrated by an object going round in a circle at a constant speed. It is changing direction all the time so that its velocity is constantly changing. It is constantly accelerating even though it is travelling at constant speed.
"acceleration"
Acceleration. Deceleration is a decrease of speed during a given interval of time.
positive acceleration
false
The shift of velocity per unit of given time is called acceleration. The types of acceleration are negative acceleration and positive acceleration.
No, it's only the acceleration. By (-)ve acceleration ,it means retardation or deceleration..
No, it's only the acceleration. By (-)ve acceleration ,it means retardation or deceleration..
acceleration
It may or may not be true: it depends on the direction in which the acceleration is being measured.
Reteradation will be half of acceleration
It will increase mass.
It is said to be accelerated
