Answer:

the rate of change of velocity with time is called acceleration.

it can also be defined as the increase in velocity per second.

The S.I. unit of acceleration is meter per second square or ms−2.

formula; a = Δv / Δt

where a is acceleration,

Δv is the change in velocity,

and Δt is the amount of time it took for that change to occur.

Explain why the force of muscle twitch can vary?

padilas [110]

Answer

Frequency of stimulus can change the force of muscle twitch.

Explanation

Twitch is tension produced by the contraction of a small muscle or it is muscle fasciculation. Its strength depends on the stimulation frequency. If the frequency is higher then temporal summation takes place and produce higher tension in the muscle. If the frequency is weak then less tension is produced in the muscle. This force also depends on the cross-sectional area of muscle.
