Speed is a scalar quantity. This means that its value stands on its own without a direction. Something similar to speed is velocity. Velocity has the same number as speed, but also includes a direction. For example, I might be driving at a speed of 60 miles per hour, whereas my velocity is 60 miles per hour, west. This type of quantity-one that includes a direction-is called a vector quantity. Acceleration, like velocity, is a vector quantity. If I continue driving at the same speed but I follow a curve in the road that changes my direction, I might then be driving 60 miles per hour, north. Since my speed remained 60 miles per hour, the number corresponding to my acceleration was zero before and is zero after. However, the change in direction means that acceleration has changed.
What else can I help you with?
Is acceleration the fastest kind of speed?
Acceleration is a measure of how quickly the speed of an object changes over time, not the speed itself. Speed refers to the rate at which an object covers distance, while acceleration refers to how the speed of the object changes. So, acceleration is not a kind of speed, but rather a measure of how speed changes.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
When an object changes speed does its acceleration change?
Yes, when an object changes speed, its acceleration changes. Acceleration is a measure of how quickly the speed of an object changes over time. So, if the speed changes, the acceleration of the object will also change.
When either a linear or angular speed is changing with time the difference in speed per unit time is called the?
The rate at which speed changes with respect to time is called acceleration. It can refer to changes in linear speed (velocity) or angular speed. Positive acceleration indicates an increase in speed, while negative acceleration (deceleration) indicates a decrease in speed.
What happens to the speed of an object that is accelerating?
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
How can one determine speed using acceleration?
To determine speed using acceleration, you can use the formula: speed initial speed (acceleration x time). This formula takes into account the initial speed of an object and how much the speed changes over time due to acceleration. By plugging in the values for acceleration and time, you can calculate the speed of the object at any given moment.
Are satellites an example of acceleration as it orbits around the earth?
Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

What is the change of speed over time?
The change of speed over time is known as acceleration. It is the rate at which an object's velocity (speed and direction) changes with time. Positive acceleration indicates speeding up, negative acceleration indicates slowing down, and zero acceleration indicates a constant velocity.
The relationship of speed and acceleration?
Acceleration is the time rate of change of speed. Acceleration = speed/time.
What is the rate at which the speed of an object changes?
The change in an objects velocity is called acceleration. The formula is:a = F/m where a is acceleration, m is the mass, and F is the force acting on the object.
How do distance-time and speed-time graphs help explain an object's motion?
Distance-time graphs show how distance changes over time, where the slope represents speed; steeper slopes indicate faster motion. Speed-time graphs display how speed changes over time, with the slope representing acceleration; a steep slope indicates rapid changes in speed. Both graphs provide a visual representation of an object's motion, helping to analyze its speed, acceleration, and distance traveled.
Compare and contrast speed and acceleration?
-- "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.
