Question

S=ut+1/2at2 Newton third law​

Answer 1

Answer:

This is a kinematic equation to show the position s(t)s(t) at time tt. There is constant acceleration aa.

s(t)=v0t+12at2s(t)=v0t+12at2

d2sdtt=s¨=ad2sdtt=s¨=a constant

Newton’s Second Law: F⃗ =Σma⃗ F→=Σma→

Newton’s Second Law states that a non-zero force causes an object to change velocity, i.e speed and direction.

The kinematic equation s(t)s(t) is a consequence of Newton’s Second Law. The constant acceleration a≠0a≠0 means the object’s movement is not a straight line.

F=md2sdtt=maF=md2sdtt=ma constant
