Unit 3

Energy

100

This is the SI unit for energy.

What are joules?

200

This is the equation for gravitational potential energy.

What is mgh?

300

If mass equals 2kg and height is 4m, this is the gravitational potential energy. Assume gravity is 9.81m/s².

What is 78.48 joules?

400

This is the kinetic energy if force is 6N, acceleration is 3m/s², and velocity 2m/s.

What is 4 joules?

500

If the total initial potential energy was 480 joules, the initial kinetic energy was zero joules, the final potential energy is 280 joules, and the mass is 4kg, this is the final velocity.

What is 10m/s?

Work

100

This is the SI unit for work.

What are joules?

200

This is the force on an object if the displacement is 8m and the work done is 40 joules.

What is 5N?

300

This is the work-kinetic energy theorem.

What is W=ΔKE?

400

Someone pulls on an object at an angle of 36 degrees from the horizontal with a force of 25N. This is the work done if the box was displaced by 8m. Assume friction is negligible.

What is 161.8 joules?

500

If the velocity of an object changes from 2m/s to 8m/s, this is the amount of work done. The mass is 2kg.

What is 28 joules?

Equations

100

1/2mv²

What is the kinetic energy formula?

200

1/2kx²

What is the equation for potential energy from a spring?

300

Fdcosθ

What is the equation for Work?

400

This is the solution to 1/2mv²_f-1/2mv²_i

What is work?

500

1/2mv²_i+1/2kx²_i+mgh_i=1/2mv²_f+1/2kx²_f+mgh_f

What is the Conservation of Energy Equation?

Power

100

This is the SI unit for power.

What is a watt?

200

These are the equations for power.

What are P=W/t and P=Fv?

300

If power is equal to 200 watts and time is equal to 60 seconds, this is the value for work.

What is 12,000 joules?

400

If mass is 2kg, distance is 10m, and time is 5 seconds, this is the power.

What is 1.6 watts?

[P=Fv ->P=mav -> P=m(d/t²)(d/t)]

500

This is the definition of power.

What is the rate at which work is done?

Pokémon

100

This is Ash's starter and the cover pokémon for pokémon yellow.

What is Pikachu?

200

These are the generation six starter pokémon.

What are Froakie, Fennekin, and Chespin?

300

In generation four, this pokémon had no weaknesses.

What is Sableye?

400

To evolve this pokémon, you must hold your console upside down.

What is Inkay?

500

This pokémon's featured episode had to be taken down due to children experiencing seizures.

What is Porygon?
