What is Acceleration? - Definition and Formula The average acceleration of an object can be calculated using the following equation: a = (vf - vi) / (tf - ti) where, a = average acceleration, vf = final velocity, vi = initial velocity, tf = final time and ti = initial time. In other words, acceleration equals the change in velocity divided by the change in time.

Mass The mass of an object determines its acceleration in the presence of an applied force. This phenomenon is called inertia. According to Newton's second law of motion, if a body of fixed mass m is subjected to a single force F, its acceleration a is given by F / m.

How is acceleration defined? A mathematical definition for acceleration is the velocity rate of change (its derivative). In the real world is easy to concretize the idea if you think in a car moving. If you accelerate/break, the speed will change positively/negatively. In the physical world, acceleration is the effect of applying forces in bodies.

How is acceleration defined? The velocity is changing over the course of time. In fact, the velocity is changing by a constant amount - 10 m/s - in each second of time. Anytime an object's velocity is changing, the object is said to be accelerating; it has an acceleration.

Acceleration In each case, the acceleration of the object is in the positive direction. In Example A, the object is moving in the positive direction (i.e., has a positive velocity) and is speeding up. When an object is speeding up, the acceleration is in the same direction as the velocity.

Acceleration Since acceleration is a velocity change over a time, the units on acceleration are velocity units divided by time units - thus (m/s)/s or (mi/hr)/s. The (m/s)/s unit can be mathematically simplified to m/s2.

Physics for Kids How to Measure Acceleration. The standard unit of measurement for acceleration is meters per second squared or m/s 2. You can calculate this from the above formula where velocity is meters per second and time is in seconds. Acceleration is a Vector. In physics acceleration not only has a magnitude (which is the m/s 2 number we discussed above), but also has a direction. This makes acceleration a vector. Force and Acceleration. Newton's second law of motion states that the force on an object equals the mass times the acceleration. This is written in the following equation: We can use this formula to also figure out the acceleration if we know the mass and force on an object.

- ACCELERATION- A measure of the rate at which a  defined amount of matter   increases/decreases its velocity. Measured in change in velocity  over a period of   time.… Acceleration is directly proportional to force. It will  increase/decrease linearly   with an increase/decrease in force if mass remains constant.

What does acceleration mean? Technically this is the formula for average acceleration since it is defined over a finite interval of time. For instantaneous acceleration, you would need to find the rate of change at a particular moment in time, which often requires calculus. Luckily for us, most introductory, algebra-based physics examples consider cases where acceleration is constant, in which case the rate of change over any interval is the same as the rate of change at any moment.

The Acceleration of Gravity It is known as the acceleration of gravity - the acceleration for any object moving under the sole influence of gravity. A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it - the symbol g.

The Acceleration of Gravity Recall from an earlier lesson that acceleration is the rate at which an object changes its velocity. It is the ratio of velocity change to time between any two points in an object's path. To accelerate at 9.8 m/s/s means to change the velocity by 9.8 m/s each second.

The Acceleration of Gravity: Definition & Formula The Acceleration Due to Gravity. The magnitude of the acceleration due to gravity, denoted with a lower case g, is 9.8 m/s^2. This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s. So, after one second, the object is traveling 9.8 m/s.
