Question

define Newton's second law of motion. find an expression for force​

Answer 1

Answer:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration.

hope it is helpful..

Answer 2

Answer:

the rate of change of momentumof a bodyis directly proportional to the applied force and takes place in tge directionin which the force acts.

Explanation:

f directly proportional to mv-mu/time taken

where f is force m is mass v is velocity or speed and u is uniform velocity or speed.

f =ma

force is equal to the peoduct of mass and acceleration
