One of the particles found in an atom.

A measurement of the amount of power an electrical current has.

What charge does an electron have?

Look at the picture! The mass of the package is 36 kg. Calculate the increase in the gravitational potential energy (g.p.e.) of the package when it is raised through a vertical height of 2.4 m.

A rifle fires a bullet of mass 0.020 kg vertically upwards through the air. As it leaves the rifle, the speed of the bullet is 350m/ s. Calculate the kinetic energy of the bullet as it leaves the rifle!

The models of train has a mass of 2.5 kg, it stopped by compressing a spring in the buffer. After the train has stopped, the energy stored in the spring is 0.48 J. Calculate the initial speed v of the train.

An energy source formed from the decomposition of dead organisms.

Complete the equation for the final pressure p2 of the gas when the gas is compressed at a constant temperature. p2 =

A gas is stored in a sealed container of constant volume. The temperature of the gas increases. This causes the pressure of the gas to increase. What happens to the kinetic energy of the gas molecules during this pressure increase?

A cup contains hot liquid. Some of the liquid evaporates. What happens to the mass and what happens to the weight of the liquid in the cup?

A resource that exists in finite amounts on our planet and cannot be replenished

What energy source production method produces the most air pollution?

A material whose atoms do not transfer, or “share,” electrons easily.
