Sample Physics questions
- Talk about Physics in the news (Pembroke, Oxford)
- Estimate the mass of rubber from car tyres left/deposited on UK roads each year (Pembroke, Oxford)
- Work out the radius of the Earth if a building has no shadow and another which is 300km away and 20m high has a 1m shadown. (Pembroke, Oxford)
- Draw a graph for velocity against height for a ball thrown vertically upwards into the air... and derive an expression for the gradient. (Pembroke, Oxford)
- Pictures of graphs were shown - and then inspect the equations (for y = e^-x^2) then x = e^-(y-1)^2 then y = x + e^-x^2 (Pembroke, Oxford)
- What would happen if we removed one leg from the Eiffel Tower (Pembroke, Oxford)
- What would happen to the Earth's rotational speed when the polar ice-cap melts? (Pembroke, Oxford)
- Work out an expression/ratio for how long the day will be...
- If you have a negatively charged ring (with a constant charge) with a radius r, what is the electric field like in the middle? (Lincoln, Oxford)
- Assume you have a charged particle in the middle... as the particle moves perpendicularly outwards from the plane of the ring. Work out an expression for force in terms of r and x...
- Estimate the number of thorium atoms in the walls of a room. If the room has intermal dimensions of 20m x 10m x 10m and the walls are 1m thick. The walls are concrete and the thorium is 5 parts per million. (Lincoln, Oxford)
- A space rocket has 2 parts, the cabin and fuel tanker. It burns fuel at a constant rate, R. (Lincoln, Oxford)
- make an expression for mass in terms of time
- make an expression for force
- make an expression for acceleration
- make an expression for displacement from the starting position (assuming that it starts with a velocity of 0)
