What is acceleration?

Answer

Acceleration is the increase in the rate or speed of something. It can also be described as the increase of motion or action. In physics, specifically kinematics, acceleration is the change in velocity over time.

Acceleration There are a few. The most famous is a = F/m , where F is the net force applied to a mass, m . Acceleration is also the change in velocity, (Delta-V), divided by the change

Ask.com Answer for: what is a acceleration
Acceleration is the rate at which an object changes its speed or velocity. The formula for finding acceleration is (Vf - Vi)/T, where Vf is the final velocity, Vi is the initial velocity and T is the time elapsed.
Acceleration is defined as the rate at which an object changes its velocity. It is a vector quantity whose SI unit is metres per second. Acceleration can either be positive or negative and it is caused by altering the speed or direction of an object.
Acceleration is described as an increasing rate of change or velocity of an object. It is measured in metres per second (m/s). It is a topic in physics that usually refers to the optimum speed a car can reach in relation to changes in variables such as time and distance.
