Elena held a rock weighing 1 N in her hand. The rock has no velocity. KE________?

Chemistry
1 answer:
nignag [31]3 years ago
5 0

KE = 0

<h3>Further explanation  </h3>

Energy is the ability to do work  

Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:  

\large{\boxed{\bold{KE=\frac{1}{2}mv^2}}}

So for two objects that have the same speed, the greater the mass of the object, the greater the kinetic energy  

The stone in hand is in a motionless state (at rest) so that its velocity (v) = 0, so it has no kinetic energy

But this stone can have <em>potential energy that is gained due to its height</em>
