acceleration is the rate at which what happens

If the speedometer of a car reads a constant speed of 40 km/h, can you say that the car has a constant velocity Acceleration is the rate at which what happens?.

The final mathematical quantity discussed in Lesson 1 is acceleration. An often confused quantity, acceleration has a meaning much different than the meaning associated with it by sports announcers and other individuals. The definition of acceleration is:. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration has to do with changing how fast an object is moving.

We are all familiar with the fact that a car speeds up when we put our foot down on the accelerator. The rate of change of the velocity of a particle with respect to time is called its acceleration. If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration. Since we are using metres and seconds as our basic units, we will measure acceleration in metres per second per second. Over the first three seconds, the particle's speed is decreasing the particle is slowing down. At three seconds, the particle is momentarily at rest. After three seconds, the velocity is still decreasing, but the speed is increasing the particle is going faster and faster.

In physics , acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law. Accelerations are vector quantities they have magnitude and direction and add according to the parallelogram law. For example, when a car starts from a standstill zero velocity, in an inertial frame of reference and travels in a straight line at increasing speeds, it is accelerating in the direction of travel. If the car turns, an acceleration occurs toward the new direction.



Speed, Velocity, and Acceleration

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. - Distinguish the difference between how to plot a velocity graph and how to plot an acceleration graph. In physics, acceleration is the rate at which the velocity of a body changes with time.
