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

What is the formula for speed and acceleration?
formula for speed is distance traveled over time taken to cover distance acceleration is given by change in velocity per unit time
Are velocity and acceleration both rates of change?
yes, velocity is a change in distance with time, and acceleration is a change in velocity with 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.
Why is acceleration a factor in force and not velocity?
Acceleration is the change of velocity over time so it is actually intimately related to velocity.
Is acceleration the change of distance over time?
No, acceleration is the change in speed over time.
Acceleration is the change in distance over time True or false?
False. Acceleration is a change of speed or direction over time.
What is the formula for speed and acceleration?
formula for speed is distance traveled over time taken to cover distance acceleration is given by change in velocity per unit time
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 are two words that describe the rate of motion of an object at a given point in time?
Velocity is the change of distance over change in time (distance/unit time) and Acceleration is the change in velocity/unit 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 .
What is the change in velocity over time?
acceleration a----->velocity=acceleration x time: v=a x t
What is the difference between Velocity and Acceleration of an object?
Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.
How do you find time when given distance and acceleration?
Distance = (1/2 of acceleration) x (time squared)You can change this around to solve it for acceleration or time.(Time squared) = (distance)/(half of acceleration)Time = the square root of [ (2 x distance)/(acceleration) ]Be careful . . .This is only true if the distance and the speed are both zero when the time begins.
What is the formula for solving acceleration?
acceleration = twice the distance over time, or the derivative of velocity with respect to time
Is acceleration the slope of a line on a distance time graph?
No. The slope of the distance-time graph is the change in distance per unit of time - otherwise known as speed. Acceleration is the slope of the speed time graph.
What is acceleration a change in over time?
Velocity.
