acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing

Answer:
m
2
+n
2
–2mn
It is given that
m=–2 and n=2
Substituting the values we get
=(−2)
2
+2
2
–2(−2)(2)
By further calculation
=4+4–(−8)
So we get
=8+8
=16
