Q:- Define Acceleration .
Answers
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:
acceleration
Step-by-step explanation:
The definition of acceleration is: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
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. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
In physics, the three types of acceleration are changes in speed, direction and both simultaneously. The word "velocity" is often used in place of speed
Unit of acceleration is the metre per second per second (m/s2). Definition. The snewton is that force which, when acting on a mass of one kilogramme, produces an acceleration of one metre per second per second
When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. In everyday English, the word acceleration is often used to describe a state of increasing speed. For many Americans, their only experience with acceleration comes from car ads.
