Kinetic energy is the energy of movement and is a function of the mass of an object and its speed: \(KE = {1 \over 2}mv^2\) where m is mass in kilograms, v is speed in meters per second, and KE is in joules. The most impactful quantity to kinetic energy is velocity as an increase in mass increases KE linearly while an increase in speed increases KE exponentially.
Which of these is the formula for kinetic energy?
\(KE = {1 \over 2}mv^2\) |
|
\(KE = mgh\) |
|
\(KE = {m \over v^2 }\) |
|
\(KE = {1 \over 2}mh^2\) |
