Energy Lesson

Energy

The ability to do work.

Work in science is the product of a force being applied to an object and the
distance over which the force is applied.

Work = Force (N) x Distance (m)

In other words, work results in the movement of an object in the same direction
that a force is applied.

Math Response

A force of 50 N is applied to an object to move it 3 meters. How much work is done on the object?

Types of Energy

Electrical

Mechanical

Chemical

Thermal

Electromagnetic

Sound

Nuclear

Multiple Choice

How many types of energy are there?

• 5

• 6

• 7

• 8

Mechanical Energy

The sum of potential and kinetic energy (KE + PE)

Potential energy is because of position or composition (stored energy).

PE = Mass x Gravity (9.8) X Height

Kinetic energy is energy due to motion of an object.

KE = 0.5 x mass x (velocity)2

Multiple Select

Mechanical energy is the sum of which 2 of the following types of energy?

• potential

• electrical

• kinetic

• thermal

Match

Match the following

• Mechanical

• Potential

• Kinetic

Sum of potential and kinetic

due to an object's position

due to the motion of an object

• Sum of potential and kinetic

• due to an object's position

• due to the motion of an object

Labelling

Label the following.​ ​

Drag labels to their correct position on the image

highest potential energy

highest kinetic energy

Electrical Energy

Results from the flow of electric charge (moving electrons)

Watt: a measurement of how quickly electrical energy is moved

Chemical Energy

Energy that is stored in the bonds between atoms.

This is a form of potential energy.

Only released when the bonds between atoms are broken.

Open Ended

Where is chemical energy stored?

Thermal Energy

The total energy of all of the moving particles in a substance.

A form of kinetic energy.

The faster the particles are moving, the more the thermal energy, which means a
higher temperature.

Multiple Choice

If the particles in an object are moving faster, the thermal energy is ____.

• lower

• higher

• zero

Electromagnetic Energy

Energy that travels in waves through space.

Multiple Select

Which of the following are types of electromagnetic energy?

• visible light

• radio waves

• gamma rays

• microwaves

Sound Energy

Energy that travels in waves, but unlike electromagnetic energy, it cannot travel
through empty space.

Open Ended

How are electromagnetic and sound energy different?

Nuclear Energy

Energy that is released during nuclear fusion or nuclear fission

Law of Conservation of Energy

Energy cannot be created or destroyed. It can travel from one place or object to another(transfer), and it can change form (transform).

Draw

Draw an energy transformation.
