Question

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

Answer 1

KE = 0

Further explanation

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=(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 potential energy that is gained due to its height
