Hi Chloe, you are working wonders with Alex's self confidence regarding her physics. She finds the structure of your lessons excellent and your explanations easy to understand. She says that you are way better than the physics teachers at school! We're very happy. Many thanks Diane

Why limit yourself to someone who lives nearby, when you can choose from tutors across the UK?

By removing time spent travelling, you make tuition more convenient, flexible and affordable

We've combined live video with a shared whiteboard, so you can work through problems together

All your Online Lessons are recorded. Make the most out of your live session, then play it back after

Usually we cover both subject knowledge and exam technique, although that can change depending on each individual student. Then we go through diagrams, and they ask questions, and we go from there.

Lots of students say that the classes are too big in school, or that they don't have time to ask teachers after Online Lessons. In my Online Lessons, we take time to explore things in a little in a bit more detail.

I always look up the board my students are taking so the Online Lessons are really relevant. Then we go through past papers or set texts, whatever the student finds helpful.

I use the shared whiteboard. We make diagrams together and label them, and often the student prints it off because they know it's right and they completely understand it.

After tutoring one girl went and told all her friends the new explanation I gave her. And she was so excited about what she wrote in the exam she emailed me immediately afterwards.

There was one girl who had her exam on Monday. She wanted tuition on Friday, Saturday and Sunday beforehand. It was very intense, but she said the exam went well.

Newton’s law of gravitation states that the force of attraction between two objects due to their masses is proportional to the product of the two objects and inversely proportional to the distance between the objects squared.

The electromotive force and the potential difference in a circuit are very similar concepts as they are both names for energy per unit charge within a circuit and they both use the same unit, Volts. The difference between the two is that the electromotive force is the voltage, the energy per unit charge, provided by an electrical source, while the potential difference is simply the difference in voltage between two points within the circuit.

The kinetic energy of the electron will be equal to the energy what the electric field gives to it.1/2*m*v^{2}=V*QFrom thisv=sqrt(2*V*Q/m)

De Broglie wavelength:lambda=h/p=h/(mv) We know that h is the planck constant, V=300V Q is the charge of an electron and m is the mass of it.

If we substitute these into the equations above we get lambda=7*10^{-11}m

Ice, in it's solid form, is at a maximum temperature of zero degrees Celsius. You might expect that a small volume of Ice might cool say a 25 degree drink to somewhere halfway between 0 and 25. This is not observed, because Ice, in addition to absorbing heat as it gets warmer, absorbs heat energy when it changes phase from solid to liquid. This is known as the specific latent heat of fusion, which is defined as: The amount of energy required to change the state of a substance from solid to liquid at a constant temperature, which for water is 334000 Joules per Kilogram. During this entire process the Ice remains at 0 degrees, and the surrounding water is kept just above this temperature until all the Ice has melted, provided there was a sufficient amount of Ice to cool the entire drink to just above zero before it had all melted.

Separately, Ice is very effective at cooling drinks quickly because convection currents are set up in the container, and quickly the entire drink becomes the same temperature.

To determine the kinetic energy of the car, we need to use the formula for kinetic energy. The formula is KE=(1/2)mv^(2) where m is the mass of the object (in kg) and v is the speed of the object (in meters per second, which is often written as (m/s)).

In the case we are looking at, our object is the car, the mass, m = 1500kg and the speed, v = 7m/s. Plugging these values into the formula for kinetic energy and using our calculator we get the following:

KE = (1/2)mv^(2) = (1/2)*1500*(7^(2)) = 36750J

With so much material to cover, GCSE and A-Level Physics can be a real challenge. Our tutors understand that very well, because they remember taking the same exams themselves. They have recent, first-hand experience of the syllabus and exam technique. They excelled in their own exams and are now studying at leading UK universities, perfectly placed to help you.

In one-to-one sessions in our online classroom your Physics tutor will create a fun and productive learning environment.They'll use diagrams, graphs and illustrations to bring the subject to life. With personal help from a Physics tutor, you'll feel prepared, confident and ready for your exams.
