When the mass of an object increases, the kinetic energy will increase, provided that its velocity remains constant. The kinetic energy (KE) of an object is given by the formula:
\[ KE = \frac{1}{2} mv^2 \]
where \( m \) is the mass and \( v \) is the velocity. If the mass \( m \) increases while the velocity \( v \) stays the same, the kinetic energy will increase since it is directly proportional to the mass.
However, if the mass increases while the velocity also changes (for example, if the object slows down), the overall effect on kinetic energy would depend on how much the mass and velocity change.
