Question

The kinetic of an object is directly proportional to ______
a) twice of its mass
b) half of its velocity
c) the square of its mass
d) the square of its velocity

Answer 1

Answer:

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

Answer 2

correct answer is option a)
