Properties of a Wave with Simple Harmonic Motion

Submitted by PocketLab on Thu, 06/01/2017 - 19:41

Exploration

Simple Harmonic Motion is a periodic or oscillating motion where the forces of the movement cause a particular motion to continually repeat. The back and forth of a pendulum, like in an old grandfather clock, the ticking of a classic metronome, or the up and down movement a bungee jumper can all be examples of harmonic motion.
Using PocketLab you can investigate how to mathematically model harmonic motion through two classic examples, a swinging pendulum and a mass-spring system.

Magnetic Minesweeper

Submitted by PocketLab on Thu, 06/01/2017 - 19:37

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.

Potential Energy to Kinetic Energy Experiment: Gravity

Energy Transfer Experiment: Gravitational Potential Energy to Kinetic Energy

Does a falling object have potential energy or kinetic energy or both? 

In other potential energy experiments, we demonstrated the  Law of Conservation of Energy: energy can neither be created nor destroyed, but instead, it changes from one form to another. 

Let's take a look at the role of gravity in energy transfer.

Energy Transfer: Elastic Potential Energy to Kinetic Energy

Submitted by PocketLab on Thu, 06/01/2017 - 18:41

Exploration

The law of conservation of energy tells us that energy can neither be created nor destroyed. Instead it changes from one form of energy to another. Potential energy is energy that is stored in an object. Potential energy can transfer into other forms of energy, like kinetic energy. Kinetic energy is energy in an object because of its motion.

Understanding Newton's Laws with Atwood's Machine

Submitted by PocketLab on Thu, 06/01/2017 - 18:37

Exploration

Acceleration of an object is dependent upon two variables – the net force acting on the object and the mass of the object. Using a Full-Atwood’s Machine you will explore the relationship between these variables to understand Newton’s Second Law of Motion.
