Forces

Gravity

We explored that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object.

 

We considered what weight is, and how the impact caused by falling objects can vary, depending on their size, shape, mass and the height they fall from.

Air Resistance

We identified and explained the effects of air resistance. We learnt how air resistance affects moving objects and planned an investigation to explore this further.

Friction

We carried out an experiment to find out which surface causes the most friction and makes it most difficult to move an object.

Water Resistance

Next, we identified and explained the effects of water resistance. By carrying out 'The Sinking Plasticine Experiment', we found out that water resistance slows an object moving through water. 

Mechanisms

We found out that some mechanisms, including levers, pulleys and gears, allow a smaller force to have a greater effect.
