What needs to be known about an object in order to determine its kinetic energy.

P.S Please help I need to answer this question for my pendulum experiment.

Answer:

Mass and velocity (or motion).

Step-by-step explanation:

KE=(1/2)mv^2.

The kinetic energy of an object is the amount of work (expended energy) that's required to move (or more accurately, to accelerate) the object to a specific velocity. So, if you know the mass of the object, and you know it's current velocity, you can determine it's kinetic energy with the formula above.
