Average acceleration over a certain time period is the difference in velocity, divided by the time. In this case, (4-2)/W.

Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?

Assuming that acceleration is constant during that time, just divide the change in speed by the time.


What are the effects of acceleration due to gravity on the time period of a pendulum?

The period of a pendulum (in seconds) is 2(pi)√(L/g), where L is the length and g is the acceleration due to gravity. As acceleration due to gravity increases, the period decreases, so the smaller the acceleration due to gravity, the longer the period of the pendulum.


What type of acceleration does a trapezium on a velocity time graph represents?

A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.


If a trucks brakes are applied for 2 seconds giving it acceleration of -3.1 ms2 what will the trucks new speed be in ms?

No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.

Acceleration is defined as a change in velocity over time. if a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds what is her acceleration?

The runner's acceleration is 0.1 m/s^2. This is calculated by taking the change in velocity (4 m/s - 2 m/s = 2 m/s) and dividing by the time taken (20 seconds).

What is its average acceleration over the first 5.1s of its motion?

To find the average acceleration over the first 5.1 seconds of motion, divide the change in velocity over that time period by the time taken. Calculate the final velocity minus the initial velocity over 5.1 seconds to find the average acceleration.


Acceleration is defined as a change in velocity over time. if a runner increases velocity from 2 ms to 4 ma over a period of 20 seconds what is her acceleration?

The idea is that you should: a) Calculate the change in velocity. b) Divide this change by the time. This gives you the average acceleration over the 20 seconds, in this case.


The increase of velocity over a period of time is?

Acceleration is the rate of change of velocity over time. So, if velocity is increasing over a period of time, there is acceleration present.

Acceleration is what?

ACCELERATION- A measure of the rate at which a defined amount of matter increases/decreases its velocity, measured in change in velocity over a period of time.=========================Answer #2:Acceleration is any change in the speed or direction of motion.


How is acceleration calcuated?

Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.
