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.You need to login to perform this action.
