PocketLab Bungee Jumper

Submitted by PocketLab on Fri, 06/02/2017 - 16:38

Exploration

A bungee jumper leaps from a tall structure and falls toward the ground. The bungee cord begins to stretch and transfers the kinetic energy of the fall into elastic potential energy, slowing the jumper to a stop.The cord then pulls him/her back up as the elastic potential energy turns back into kinetic energy. The jumper then oscillates up and down until their energy is completely dissipated.

Simple Pendulum Motion

Submitted by PocketLab on Fri, 06/02/2017 - 16:34

Exploration

A simple pendulum consists of a mass, m, hanging from a string of length, L, and fixed at a pivot point, P. When displaced from equilibrium and to an initial angle (amplitude, θ) and released, the motion will be regular and repeat. This is an example of periodic motion.

Exploration

In the Magnetic Minesweeper Lab, you will recreate the classic computer game Minesweeper in real life! Using PocketLab’s magnetometer, you will try to discover hidden mines and mark their locations on a grid. You can do this lab with two people to create a Minesweeper competition. One partner hides mines in different grid locations while the other partner tries to locate the mines to not get blown up!

How does distance affect the strength of a magnetic field?

Exploration

Can you throw a baseball without touching it? No, your hand needs to push the baseball forward as your throw it. Objects often interact like this, through contact. The baseball will then stop moving after contacting the ground or a catcher’s mitt. But can two objects interact when they aren’t in contact, when they are instead, at a distance from each other? Using PocketLab, you can explore how this might be possible.

Magnetic Field in a Slinky

Exploration

Until the late 1800’s, electricity and magnetism were regarded as separate forces. A number of scientists, including Michael Faraday and James Clerk Maxwell, made important discoveries which led to our current understanding of electricity and magnetism. The interaction between positive and negative charges is, in fact, one force, the electromagnetic force, which results in both electrical currents and magnetic fields.

Projectile Motion of an Object

Submitted by PocketLab on Thu, 06/01/2017 - 19:22

Exploration

When an object is in free fall, the only force acting on the object is gravity. In general terms, an object moving upward is not considered “falling,” however, if gravity is the only force acting on the object (air resistance being negligible) then the object is in fact in a state of free fall. The projectile motion of an object is the trajectory of an object in free fall near Earth’s surface after being thrown or launched in the air. The curved path of the projectile is under the effect of gravity only after being launched.

Introduction to Free Falling Objects

Exploration

Galileo Galilei is often considered one of the founders of modern science. This is because he investigated questions through experimentation and observations. One of his most famous experiments involved dropping cannonballs of different mass to determine whether they would accelerate to the ground at different rates.

Energy Transfer: Kinetic Energy to Thermal Energy

Submitted by PocketLab on Thu, 06/01/2017 - 19:09

Exploration

The law of conservation of energy states that the total energy of an isolated system remains constant. Over time, all energy is conserved. It is neither created nor destroyed-instead it transfers from one form to another. When shaking a jar of sand, what happens to the temperature of the sand? Explore how this relates to the law of conservation of energy.
