Physiology: Structure and Movement

Force Platform

Measure the forces of human activity - jumping, stepping, pushing, and hitting. Students will see how much force they exert -- and is exerted on them -- in every day behavior. Learn more

Human Arm Model

Demonstrate for your class the forces at work inside the human arm. PASCO's Human Arm Model is both a mechanical model and a PASPORT Sensor - observe the action and see the data in real-time. Learn more

Show your students the forces involved in their everyday activity.

The PASPORT Force Platform is the perfect way to measure forces generated by students actions -- stepping, jumping, pushing, and hitting.

Students jump from the Force Platform and they can observe the force exerted, or measure the hang time of their jump. See the force generated during a push-up.

Typical uses of the Force Platform

• Determine "hang time" by jumping up from the platform, then landing on it
• Measure impulse and maximum force when jumping
• Use two Force Platforms to investigate Newton's 3rd Law as two students push against each other
• Measure the normal force on a person riding in an elevator
• Use a Motion Sensor and a bouncing ball to compare the impulse and change in momentum as the ball collides with the platform

Here's what you need:

• PASPORT Force Platform (PS-2141)

Explore the forces exerted on the human body in everyday situations, sports, and large-scale physics experiments. Large surface area (35 cm x 35 cm) -- no need to be timid with this product, it is designed for jumping!

Optional Equipment:

• Handle Set (PS-2548)

You can do quite a bit of measurement with the Force Platform as is, but when you add this Handle Set, you get even more flexibility. Push against a wall or even have two students push against each other using two Force Platforms -- a great demonstration of Newton's Third Law.

Simulate the muscles and motion of an actual human arm.

The Human Arm Model simulates the muscles and motion of an actual human arm. Full range of motion including throwing, curling and extension can be measured.

• Capture muscle tension, shoulder and elbow joint movement data
• Measure force and angle simultaneously
• Link tricep and bicep muscle action to arm motion

Here's what you need:

• Human Arm Model (PS-2611)

The Human Arm Model simulates the muscles and motion of an actual human arm. The Arm can perform many types of motion such as extending and lifting an object, curling, or throwing a ball overhand. Different arm muscles are activated depending on which pulleys are selected. Static force measurements can also be made to see how the muscle tension changes at various arm positions.

• PASPORT Force Sensor (PS-2104) (need 2)

The study of force is critical to many science explorations. An accurate and rugged sensor will ensure your students get the most out of their force experiments. Our Force Sensor is so strong that even if a student attempted to lift a person, the sensing element wouldn't be damaged.

• Xplorer GLX (PS-2002)

Provides convenient and powerful data collection and analysis --even without a computer. Includes 2 temperature sensors, voltage sensor, built-in speaker and sound sensor. Data collection is completely portable -- in a lab or in the field. And data is easily transferred via USB Flash Drive for lab write-ups at home or in the computer lab.

Optional Equipment:

• Large C-Clamps (SE-7285) (6-pack).

Attach the Human Arm Model to a table.
