The correct equation for an object's kinetic energy is KE=1/2mv^2.
To understand how to get this equation, let's break it down:
1. The symbol KE represents the kinetic energy of an object.
2. The factor 1/2 is a constant that comes from the mathematical derivation of kinetic energy.
3. The symbol m represents the mass of the object. The greater the mass, the greater the kinetic energy.
4. The symbol v represents the velocity (or speed) of the object. The greater the velocity, the greater the kinetic energy.
5. The exponent 2 (v^2) indicates that the velocity is squared in the equation. This means that the effect of velocity on kinetic energy is nonlinear - doubling the velocity will result in a fourfold increase in kinetic energy.
So, the equation KE=1/2mv^2 represents the relationship between an object's mass, velocity, and its kinetic energy.
