Question

write five differences between work and energy

Answer 1

WORK:
1. Work the transfering of an energy's amount via a force through a distance via the direction of the force
2. SI unit if work is Joule (j)
3. work is equal to the product of force and displacement [work (w) = force(f) * displacement (s)]
4. work is a scalar quantity
5. example- a student lifting a bagpack full of books upon his/her shoulder

ENERGY:
1. energy is the alk difined as the abilty of push or pull by exertion in a certain path or distance
2. SI unit if energy id Joule (j)
3. kienetic energy = 1/2mv^2 and potential energy = mgh
4. energy is a scalar quantity
5. example- a dog barking is a type of sound energy

Answer 2

Answer:

Work:

• Work measures the transfer of energy which involved in moving an object by action of an external force.
• Work is calculated by using formula:

       Work = Force × distance

• The components of the force are parallel to the component of  displacement.
• If the applied force is in the same direction of the displacement then work will be positive and if in the opposite direction of the displacement then work will be negative.

Energy:

• Energy concerns with the capacity of an object to do work. Energy describes to the ability of a physical system to undergo work.
• Depending upon the types of energy, there are various equations foe energy.
• Energy is the result of the work performed by an object or system.
• Energy is a scalar quantity.
• Energy also consists types such as kinetic, potential, mechanical and electrical energy.
