A) velocity
B) acceleration
C) kinetic energy
D) displacement
Correct Answer: C
Solution :
Key Idea: Speed is a scalar quantity, while velocity a vector quantity. When a body moves with speed \[v,\]the kinetic energy of body is \[K=\frac{1}{2}m{{v}^{2}}\] Since speed (magnitude of velocity) is constant throughout motion, so kinetic energy of body does not change. While velocity changes continuously, because of which acceleration and displacement also changes.You need to login to perform this action.
