Vernier Motion Detector
Order code: MD-BTD
VERNIER MOTION DETECTOR
For use in: Physics, Physical Science.
The Motion Detector functions like the automatic range finder on a Polaroid camera. This sonar device emits ultrasonic pulses and waits for an echo. The time it takes for the reflected pulses to return is used to calculate distance, velocity and acceleration. The range is 0.4 to 6 meters. Our Motion Detector has a pivoting head, rubber feet and a clamp for mounting. In addition, the cable is removable, so you can convert the Motion Detector for use on a different lab interface by using the relevant cable.
Specifications:
Using a ball toss and the Motion Detector to measure the acceleration due to gravity.
Frequency of the ultrasound: 49.4 kHz
Resolution: 1.1 mm
Typical Accuracy: ± 2 mm
Range: 0.15 to 6.0 meters
Power: about 51mA @ 5 V DC while running
Size: approximately 146mm x 38mm x 57mm
Weight: approximately 283g

This product is used in teaching these Australian Curriculum codes:
ACSSU190 - Physical Sciences - Energy Conservation - Energy conservation in a system can be explained by describing energy transfers and transformations
ACSSU229 - Physical Sciences - Forces and Motion - The motion of objects can be described and predicted using the laws of physics
ACSPH066 - Linear Motion and Waves - Linear motion and force - Collisions may be elastic and inelastic; kinetic energy is conserved in elastic collisions
ACSPH065 - Linear Motion and Waves - Linear motion and force - Energy is conserved in isolated systems and is transferred from one object to another when a force is applied over a distance; this causes work to be done and changes to kinetic and/or potential energy of objects
ACSPH064 - Linear Motion and Waves - Linear motion and force - Momentum is a property of moving objects; it is conserved in a closed system and may be transferred from one object to another when a force acts over a time interval
ACSPH063 - Linear Motion and Waves - Linear motion and force - Newton’s Three Laws of Motion describe the relationship between the force or forces acting on an object, modelled as a point mass, and the motion of the object due to the application of the force or forces
ACSPH061 - Linear Motion and Waves - Linear motion and force - Representations, including graphs and vectors, and/or equations of motion, can be used qualitatively and quantitatively to describe and predict linear motion
ACSPH060 - Linear Motion and Waves - Linear motion and force - Uniformly accelerated motion is described in terms of relationships between measurable scalar and vector quantities, including displacement, speed, velocity and acceleration
ACSPH062 - Linear Motion and Waves - Linear motion and force - Vertical motion is analysed by assuming the acceleration due to gravity is constant near Earth’s surface
ACSSU033 - Physical Sciences - Forces and Moving - A push or a pull affects how an object moves or changes shape
ACSSU117 - Physical Sciences - Forces and Machines - Change to an object’s motion is caused by unbalanced forces, including Earth’s gravitational attraction, acting on the object
