Cobra DigiCart Basic Set

Function and Applications

The Cobra DigiCart Basic Set is a portable physics laboratory for carrying out 8 experiments on various topics in dynamics. The set includes a measuring cart, a track and basic accessories. Three sensors are integrated into the measuring cart. The measured values are transmitted to end devices via wireless data transmission using the Bluetooth 4 standard. Usable with tablets and desktop PCs in combination with the free DigiCartAPP or the free measureAPP on all common operating systems.

Benefits

The DigiCart is a portable physics laboratory with two measuring carts, a track and basic accessories:

• Minimal preparation time: Digital experiment descriptions are available for all experiments.
• Easy execution: Using the free DigiCartAPP, experiments can be carried out and evaluated in just a few clicks.
• Flexibility: Connect the measuring cart to the free measureAPP and perform your own experiments.
• Make concepts tangible: Measurable but often invisible physical quantities are visualized in real time.
• Low-friction rollers for unaltered measurements.

Carry out experiments on a wide range of topics in dynamics:

• Kinematics
• Newton’s laws
• Inclined plane
• Momentum

Teach the fundamentals of the following concepts:

• Velocity
• Momentum
• Force
• Acceleration
• Energy

Using the integrated sensors, a wide range of physical quantities can be investigated in real time:

• Force
• Acceleration
• Position
• Velocity
