-- "Speed" is the rate at which distance changes.

-- "Velocity" is speed along with the direction of motion.

-- "Acceleration" is the rate at which velocity changes, including the direction of the change.

Speed is a scalar quantity that refers to how fast an object is moving. Speed can be thought of as the rate at which an object covers a distance.

While velocity is a vector quantity that refers to the rate at which an object changes its position. But when we calculate speed and velocity what we get is average not instantaneous.

Average Speed= Distance travelled

Time period

Average Velocity= Displacement

Speed: Distance moved per time unit (rate of change of position).

Velocity: Similar to speed, but velocity is a vector. In other words, the word "velocity" is used in physics, when the direction of movement is relevant.

Acceleration: Change of velocity per unit time (rate of change of velocity).

Both speed and velocity are measured in meters per second (or any other unit of length divided by a unit of time), while acceleration is measured in meters per second squared (or any other combination of units of distance / time / time).

Compare and contrast speed and acceleration?

Compare velocity from acceleration?

Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)


Can you Compare and contrast speed velocity and acceleration?

Velocity and acceleration are both used to describe motion and both are vector quantities. Each one is a measure of change over time. Velocity is equal to the change in position over time, while acceleration is equal to the change in velocity over time. Velocity can be determined by determining the slope of a position-time graph, while acceleration can be found by determining the slope of a velocity-time graph.


If an object is moving at a constant velocity what do you know about its acceleration?

"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.


Is it possible for a body to have acceleration when moving constant speed and constant velocity?

No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.


Is there an acceleration when an object traveling at constant velocity and why?

No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.


How is speed velocity and acceleration alike?

Acceleration is the derivative of velocity. In other words, acceleration is the rate at which the velocity is changing.


When a body has velocity no constant has acceleration or no?

Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.


Is it possible for a body to have an acceleration when moving with constant velocity?

No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.


What is the change in velocity over time?

acceleration a----->velocity=acceleration x time: v=a x t


How does acceleration and velocity differ?

Acceleration is the rate at which velocity is changing.


Does velocity differ from acceleration?

Acceleration is the rate of change of velocity.
