Question

energy is constantly changing between potential and kinetic. which of the following is true of kinetic energy? an object has kinetic energy when it is holding still, but poised in a position to move. an object has kinetic energy when it is in motion. the slower an object is moving, the more kinetic energy the object has.

Explanation:

Kinetic energy is the energy of motion. The formula for kinetic energy is \(KE=\frac{1}{2}mv^{2}\), where \(m\) is mass and \(v\) is velocity. If an object is holding still (\(v = 0\)), \(KE=0\). As velocity (\(v\)) increases, kinetic energy increases (since \(KE\) is proportional to \(v^{2}\)). So, an object has kinetic energy when it is in motion.

Answer:

An object has kinetic energy when it is in motion.
