Why do things float? (Physics (11-14) eBook)
In this simple investigation, a block of solid material is lowered into water. The force the block exerts on the Force sensor when it is suspended in air is compared to the force it exerts on the sensor when suspended at different depths in water

Upthrust and floating (Physics (11-14) eBook)
When it was first proposed to build ships out of iron many people laughed at the idea, common experience told them iron sinks and wood floats. This was why ships were made of wood. Most students will still think along these lines. Here is a way of addressing the conflict.

Stretching materials using a distance and force sensor (Physics (11-14) eBook)
Students are asked to hang mass onto materials and measure the extension caused by the stretching force. In this version, the stretching force is measured directly by a Force sensor in newtons (N)

Measure the friction that stops and object moving. Basic method that could be adapted to other investigations.

Forces, levers and moments (Physics (11-14) eBook)
In these two experiments, we are looking at the turning effect produced when a force acts around a pivot. During the course of the investigations the students will also be introduced to the idea of the ‘moment of a force’ and how to calculate it.

Levers, balance and mechanical advantage (Physics (11-14) eBook)
In these two experiments, we are looking at the turning effect produced when a force acts around a pivot. During the course of the investigations the students will also be introduced to the idea of the ‘moment of a force’ and how to calculate mechanical advantage.

Centripetal force in a pendulum. (Physics (14-18) Motion & Forces eBook)
This experiment measures the centripetal force acting on the bob of a pendulum, and the speed of the bob. The force in the pendulum is measured continuously, and the speed of the bob is measured as it passes through the mid point of the oscillation.

Forces acting on a floating object (Physics (14-18) Motion & Forces eBook)
When it was first proposed to build ships out of iron many people laughed at the idea, common experience told them iron sinks and wood floats. Measure the forces in floating to explain why iron can float! 

How does upthrust change as object sinks? (Physics (14-18) Motion & Forces eBook)
1. The upthrust increases as the object sinks further into the liquid. 2. The upthrust is proportional to the depth (h) immersed. 3. Upthrust is equal to the weight of liquid displaced – Archimedes Principle. 

Upthrust and density (Physics (14-18) Motion & Forces eBook)
The upthrust depends on the density of the liquid, the more dense the liquid the greater the force should be required to sink an object into the liquid. Why is it easier to swim in salty water or the dead sea?
