Outcomes

1.4 recall and use the relationship between acceleration, velocity and time:<math>acceleration = change in velocity / time taken</math><math>a = (v - u)/ t</math>

Electrical Force - balloons for electrostatics, rice in a plastic bottle charging polythene rods and using watch glass show repulsion
Frictional- slope with different objects (car, glass block and wooden block) where they change and measure the angle + hovercraft
Magnetic - 2x bar magnets, iron filing in a boiling tube, horse shoe magnets attached to two vehicles with ability to reverse them.
Upthrust - pieces of wood in water, different sized paper boat with paper clips to add, transparent water bath
Strain/Spring force- spring and masses, rubber bands, squashy ball
Gravitational – different masses on a Newton Scale, planetry model
Applied Force – Push or Pull and Thrust – pulling brick with Newton meter, stones on a tray and water jug, stream of peas to drop onto a balance, balloon with a small tube and placed over a large retort stand + balloon pump
Air resistance force/drag– ball bearing dropping through oil, model of dolphin, dropping ball and feather
Tension Force- ball and string, tyrolean traverse with barbie attached
Normal Force- block and strong card

A tank with water in it will be heavy and so is only to be moved by the technician; please refer to the Manual handling section of the Laboratory Lessons Health and Safety Risk Assessment
When using springs, goggles must be worn
The main risk is from the vacuum pump and apparatus. The specific risk assessment must be read before using the apparatus.
