All objects will acceleration due to gravity. On the Earth, close to the surface objects accelerate at 9.8 ms-2 . Now you’ve finished the electricity & energy unit, try some past paper questions from old credit & intermediate 2 exam papers. Given that it takes 8 minutes for light to get from the sun, how far is it away is it from the Earth? Here are some videos on balanced and unbalanced forces affecting the motion of objects. The first clip examines the forces on a cyclist as she cycles round a velodrome. The activity of a source drops from 448 kBq to 3.5 kBq in 17.5 years. Calculate the half life of the source.

This short video shows a night-time re-entry over Mexico, with the orbiter on its way to land at the Kennedy Space Centre. There are no engines running, all that heat is being produced by re-entry to the atmosphere.A geostationary satellite is not actually stationary. By rotating at the same rate as the Earth, the satellite always appears to sit in the same point in our sky. This is quite handy, since it would be a nuisance if we had to move dish aerials to follow the location of a satellite broadcasting our TV signals.

Can you use the kinetic theory of gases to describe the pressure-temperature, pressure-volume or volume-temperature relationships? If you are having difficulties with this, try reading this blog post.There are useful set of series and parallel resistor activities here. Use the next button or follow links in the left sidebar to progress through the topic. Weight is the force of gravity acting on an object pulling it towards the centre of the Earth or any other large mass. Weight is a force and so is measured in Newtons. The weight of an object varies depending on where you are (which planet etc and how far you are from it’s surface, the further away from the surface the smaller is your weight).. Inertia is the property of an object which makes it hard to get an object to move, or to stop a moving object. Inertia varies with mass, so the bigger your mass the bigger your inertia..
