Answer:
potential energy is a stored energy or energy of position (gravitational).
Kinetic energy is a energy of motion.
Explanation:
in the formula K is for the kinetic and the P stand for the potential.
As per Definition of acceleration we know that rate of change in velocity of object is known as acceleration

so when we apply push on an object that push or applied force will change the velocity of object always
so correct answer must be
a.) changed the velocity
Answer:
An object at rest will stay at rest and an object in motion will stay in motion unless it is acted upon by an unbalanced/external force.
I think this is the answer:
<span>Matter can change its state because of the pressure and/or the temperature.</span>
