Kinetic energy is a scalar and has the same units as work (i.e. [[Joule]]).  

Kinetic energy is a scalar and has the same units as work (i.e. [[Joule]]).  

Note that if the mass of an object is increased, the increase in kinetic energy increases linearly; if the velocity of an object is increased, the increase in kinetic energy increases exponentially. E.g., doubling the mass of an object doubles its kinetic energy; doubling its velocity quadruples its kinetic energy.  

Note that if the mass of an object is increased, the increase in kinetic energy increases linearly; if the velocity of an object is increased, the increase in kinetic energy increases quadratically. For example, doubling the mass of an object doubles its kinetic energy; doubling its velocity quadruples its kinetic energy.
