acceleration is the change in speed in a certain amount of time
eg
a car goes from 4km/h to 10km/h in 3 seconds, what is its acceleration?
10km/h - 4km/h=6
6/3 secounds=2
acceleration is 2km/h
acceleration= change in speed/time

No, acceleration is the rate of change of velocity over time, not distance. It measures how quickly an object's velocity is changing, either in magnitude, direction, or both.

What is the formula for speed and acceleration?
The formula for speed is speed = distance / time, where speed is measured in m/s or km/h. The formula for acceleration is acceleration = change in velocity / time taken, where acceleration is measured in m/sĀ².
To find the acceleration of an object moving in a straight line you must calculate the charge in distance during unit of time?
To find the acceleration of an object moving in a straight line, you must calculate the change in velocity during a unit of time. Acceleration is the rate of change of velocity over time, not distance. It is given by the formula acceleration = (final velocity - initial velocity) / time.
Are velocity and acceleration both rates of change?
Yes, velocity is the rate of change of an object's displacement over time, while acceleration is the rate of change of an object's velocity over time. Velocity indicates how fast an object's position changes, while acceleration describes how the velocity of an object changes over time.
When will you say a body is in uniform acceleration non uniform acceleration?
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
When will you say a body is in uniform acceleration and non-acceleration?
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.
Is acceleration the change of distance over time?
No, acceleration is the change in speed over time.
How does the unit of time enter twice in the unit of acceleration?
Acceleration is the rate of change of velocity over time. Since velocity is distance over time, acceleration becomes distance over time squared. This is why time enters twice in the unit of acceleration as distance per time squared.
Acceleration is the change in distance over time True or false?
False. Acceleration is the rate of change of velocity over time. It measures how quickly an object's velocity is changing, not its distance.
What is the formula for solving acceleration?
The formula for acceleration is acceleration (a) = change in velocity (Īv) / time taken (Īt). This means that acceleration can be calculated by dividing the change in velocity by the time taken for that change to occur.
What is the formula for speed and acceleration?
The formula for speed is speed = distance / time, where speed is measured in m/s or km/h. The formula for acceleration is acceleration = change in velocity / time taken, where acceleration is measured in m/sĀ².
How is a speed graph different from an acceleration graph?
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
What is the equation for average speed and acceleration?
Average speed = Distance travelled/time to travel the distance . Average acceleration = Change of speed/time for the change .
How is average velocity different from acceleration?
Average velocity measures the displacement of an object over time, while acceleration measures the rate of change of an object's velocity over time. In other words, average velocity looks at the overall change in position, while acceleration focuses on how quickly that change in position is occurring.
Why do we measure acceleration in squared seconds as opposed to just seconds?
Acceleration measures the rate of change of velocity over time. The squared seconds unit is used because acceleration is the change in velocity per unit time, so it is expressed as distance per time squared. This allows us to quantify how quickly the velocity of an object is changing over time.
What is the relationship between acceleration velocity time and distance?
Velocity is the derivative of position with respect to time (v = dx/dt). Acceleration is the derivative of velocity with respect to time (a = dv/dt) and therefore the second derivative of position with respect to time (a = d2v/dt2). A derivative basically refers to the "rate of change" - graphically, it is the slope on a curve.
