Average acceleration over a certain time period is the difference in velocity, divided by the time. In this case, (4-2)/W.
It is 2/W ms-2.
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
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.
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.

Acceleration
It is 0.1 metre per second-squared.
It is 0.1 metre per second-squared.
It is 0.1 metre per second-squared.
It is 0.1 metre per second-squared.
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
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.

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.
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.
Increase of velocity over a period of time is called acceleration.
Literally the definition of acceleration.
Acceleration is a change in velocity over a period of time.
