ENERGY

Question 1

What is energy

Answer 1

The ability to do work

Question 2

What is energy measured in?

Answer 2

Joules or kilojoules

Question 3

What are the two types of energy?

Answer 3

Kinetic and potential

Question 4

What is kinetic energy?

Answer 4

Kinetic enrgy is the energy of movement. It involves movement of particles or objects.

Question 5

What are the different forms of kinetic energy?

Answer 5

Sound energy
Light energy
electrical energy
Gravitational energy
Internal (thermal/heat)

Question 6

What is potential energy?

Answer 6

This is energy stored in substances. Potential energy depends on the position of the object

Question 7

What are the different forms of potential energy?

Answer 7

Gravitational energy
Strain energy
Chemical energy

Question 8

Describe Sound energy

Answer 8

Sound energy is produced when an object vibrates, causing particles in the surrounding medium to move. These vibrations travel in waves and our ears pick up these waves and intepret them into sound

Question 9

Describe light energy

Answer 9

Light energy is a type of electromagnetic energy that travels in waves and we can detect with our eyes. When light hits an object, it can be reflected, absorbed, or transmitted. The energy from light can produce heat, cuase chemical reactons, or create electricty

Question 10

Describe internal energy

Answer 10

Internal energy is the total energy stored in a substance due to the movement and arrangement of its particles. The particles posses a certain amount of energy, which allows them to move. When a substance is heated, this movement increases

Question 11

Describe Electrical energy

Answer 11

Electical energy is the energy caused by the movemnt of electric charges through a conductor. Electrical energy needs a circut. It can be stored or produced.

Question 12

Describe Gravitiational Potential energy

Answer 12

Gravitational Potential Energy (G.P.E) is the energy an object has because of its height above the ground. The higher it is, the more energy it has due to gravity

Question 13

Describe Strain energy

Answer 13

Strain enrgy is the energy an object has when its stretched, compressed, bent, or twisted. Some materials can easily be compressed, bent or twisted but spring back into shape once the force acting on them is removed. When a elastic material’s shape has changed, they store energy in a form that will allow them to return to their original state

Question 14

Describe Chemical Potential Energy

Answer 14

Chemical Potential enrgy is the enrgy stored in the chemical bonds of a substance
