Hello There!
-Energy Is The Ability To Do Work-
Energy comes into different forms but they can all be placed in two different categories. These categories are "potential" which means stored energy and energy of position and "kinetic" which is the energy of motion.
POTENTIAL ENERGY <em>Stored energy and the energy of position</em>
CHEMICAL ENERGY <em>Energy in the bonds of atoms and molecules</em>
MECHANICAL ENERGY <em>Energy stored in objects by tension</em>
NUCLEAR ENERGY <em>Energy stored in the nucleus of an atom</em>
GRAVITATIONAL <em>Energy that is stored in an object's height</em>
ELECTRICAL ENERGY <em>Delivered by tiny charged particles called electrons</em>
KINETIC ENERY <em>The energy of motion</em>
THERMAL ENERGY <em>The vibration and movement of atoms and molecules in substances.</em>
RADIANT ENERGY<em> </em><em>Electromagnetic energy that travels in waves</em>
D.
Most are poor conductors of electricity.
<span>F = ma
</span>Ff = μ*Fn
<span>Fn = Fw
</span>Fw = mg
<span>So we have: </span>
<span>Ff = μmg </span>
<span>And </span>
<span>Ff = ma </span>
<span>So... </span>
<span>μmg = ma </span><span> </span>
<span>μg = a </span>
<span>And we can solve for the acceleration: </span>
<span>(0.15)(9.81 m/s²) = a </span>
<span>a = 1.47 m/s² </span>
Answer:
2 and 3
Explanation:
because that's how kinetic and potential energy work
Answer:
The mass of the body is 50 kg.
Explanation:
We have,
Force acting on a body is 100 N
Acceleration of the body is 2 m/s²
It is required to find the mass of the body. The force acting on a body is given by :
F = ma
So, the mass of the body is 50 kg.
