The Accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or dynamic - caused by moving or vibrating the Accelerometer.

There are 2 accelerometer sensors, a Low g 3-Axis type and a High g 2-Axis (Order No. 3201).

This Accelerometer records to a maximum of 20 g making it suitable for small accelerations such as change of g investigations e.g. free fall, golf swings.

This Accelerometer has 19 ranges and can record

• Acceleration along a single axis using a particular axis range i.e. X, Y or Z.
• Resultant Force – the sum of the force in all component accelerations (X, Y and Z).
• Vibration by sensing the amount of dynamic acceleration
• Angle (Inclinometer) by measuring the amount of static acceleration due to gravity to find the angle the device is tilted at with respect to the earth.

(The High g 2-Axis type will record accelerations along 2 single axes (X and Y) to a maximum of 40 g and the resultant force of 2 axes to a maximum of 50 g,).

Both Accelerometers can show the acceleration as multiples of g or as ms^-2.

The Accelerometer is supplied with a kit that allows the sensor to be attached to the top of a Dynamics cart.

Use the Low g 3-Axis Accelerometer to study:

• Bungee jump
• Pendulum
• Changes in acceleration in a golf swing
• Explanation of free fall
• Explanation of opposing forces e.g. resistive forces countering force of mass on a surface
• Tilt of an object
• Earthquake simulation e.g. test how long your model of a tower stays upright
