Proper acceleration, the acceleration of a body relative to a free-fall condition, is measured by an instrument called an accelerometer. Newton's second law is normally applied in an inertial …

Acceleration is the rate at which they change their velocity. Acceleration is a vector quantity; that is, it has a direction associated with it. The direction of the acceleration depends upon which …

In everyday conversation, to accelerate means to speed up. The accelerator in a car can in fact cause it to speed up. The greater the acceleration, the greater the change in velocity over a …

Dec 5, 2025 · 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 …

Acceleration is the rate at which velocity changes. In symbols, average acceleration is a= Δv/Δt. The SI unit for acceleration is m/s². Acceleration is a vector, and thus has a …

Acceleration is the rate of change of velocity with time. An object accelerates whenever it speeds up, slows down, or changes direction.

And while this is certainly one case of acceleration, in physics, acceleration refers more broadly to any change in velocity —whether an object is speeding up, slowing down, or changing direction.

Acceleration is defined as the rate of change of velocity. Acceleration is inherently a vector quantity, and an object will have non-zero acceleration if its speed and/or direction is changing.
