Answer:
Both speed and mass causes the kinetic energy to change.
Explanation:
The energy an object because of its motion is called as Kinetic energy. A object that moves be it horizontal or vertical direction possess kinetic energy. Some forms of kinetic energy are rotational, vibrational, translational. The kinetic energy(K) of the object depends on two components i.e., the mass (m) of the object involved and its speed(v)
The relation between the mass, speed of the object can be represented as
[tex]\text{Kinetic energy}=\frac{1}{2}$ mass $\times$velocity$^{2}$[/tex]
Kinetic energy$=\frac{1}{2} m \times v^{2}$
Thus when there is a increase in the mass and speed, the kinetic energy will also increase
