Potential and Kinetic Energy for Kids

Potential and Kinetic Energy for Kids

Potential and Kinetic Energy. The law of conservation of energy. Energy cannot be created. Energy cannot be destroyed. It can only be converted from one form to another. The unit of energy is joules. The formula for potential energy is mgh, M is equal to Mass, g is equal to gravitational acceleration and h is equal to height. When we fall, potential energy starts getting converted to kinetic energy. Just before we land, all potential energy gets conveerted to kinetic energy. To calculate kinetic energy, kinetic energy is equal to 1 upon 2 into m into v square, where m is equal to mass and v is equal to velocity. Subscribe to our YouTube channel: Smart Learning for All.

Let l be the length of the pendulum, When the bob is slightly displaced and released, it oscillates about its equilibrium position. Please like our facebook page http://www.facebook.com/tutorvista

Time period of a pendulum depends on its length | Oscillation| Physics

String up a pendulum, move the bob to one side and let go to set the pendulum into oscillations. Use a stopwatch to measure the time the pendulum takes to complete ten oscillations. Diving this time by 10 gives us the period of the pendulum i.e. the time taken to undergo one oscillation. Decrease the pendulum's length and repeat the above to get the new time period. We see that as the length becomes shorter, the time period decreases. This shows us that the length of a pendulum and its time period are related

Work, Energy, and Power: Crash Course Physics #9

When you hear the word, "Work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics and today, Shini is going to walk us through it.

The Pendulum and Galileo

The Pendulum and Galileo

Purchase: http://hilaroad.com/video/ Galileo's investigation of the pendulum played a role in the evolution of science. He performed some of the first experiments while discovering the relationship among length, mass and displacement. If you are teaching the scientific method, the pendulum is a good project to start with. Galileo probably gained insight into many issues around motion from his investigation of the pendulum. The video also mentions issues with the church and academia.

THE SCIENCE BEHIND NEWTON'S CRADLE

THE SCIENCE BEHIND NEWTON'S CRADLE

Newton's Cradle explained through simple science! Written and edited by: Kevin Wei --- This video was a project for my high school physics class. It was awarded "honorable mention" in the 1st Annual Southern California American Association of Physics Teachers: Student Physics Video Contest (http://www.physicsvideos.net/contest2012.html). Kevin Wei http://kevwei.com Facebook: http://www.facebook.com/KevinWeiTV Inquiries: thekevinway at gmail Made with my good friend Juan David Lopez: http://www.youtube.com/KineCinemaMedia --- VIDEO TRANSCRIPT: You may have seen this gadget lying around in places like office cubicles. The Newton's Cradle is an apparatus which consists of several rocking metallic spheres. It is commonly seen as an executive toy -- a novelty item that is left on the desk of corporate executives and other office employees, yet serves absolutely no work-related purpose. Named after the physicist Sir Isaac Newton, it demonstrates the conservation of momentum and energy. If one ball is raised, what do you think will happen when it is released? First, let's look at some physics principles. Newton's Cradle is a prime example of an elastic collision. In an elastic collision, two objects collide and return to their original shapes with no loss of total kinetic energy, just like pool balls. The law of conservation of momentum states that the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects. What this basically means is that the momentum that one ball loses its equal to the momentum that the other one gains. Also, energy is conserved. As the first ball is raised, the system's gravitational potential energy increases. When it is released, the ball gains kinetic energy. At the bottom, also known as it's equilibrium point, it's energy becomes solely kinetic. As the ball swings past its equilibrium position, the kinetic energy decreases while the gravitational potential energy increases. In a vacuum, Newton's Cradle will ideally run forever due to the absence of fictional forces. Because of the conservation of energy and momentum, the distance here (show initial height) is almost the same as the resulting height here (show final height). As Newton has started, forces always exist on pairs. The initial force is ideally equal and opposite to its resulting force.

What is a Pulley? - Simple Machines | Mocomi Kids

What is a Pulley? - Simple Machines | Mocomi Kids

http://mocomi.com/ presents: What is a Pulley? Pulley is a simple machine and comprises of a wheel on a fixed axle, with a groove along the edges to guide a rope or cable. Pulleys are used to reduce the time and energy taken to lift heavy objects. Here, Load = the weight of an object Effort = the amount of force required to lift or move this object. When you put two or more wheels together, and run a rope around them, you have created a great lifting machine. As you add more pulleys, you increase your mechanical advantage and it becomes very easy to lift the same load. The trade-off is that as you increase the number of pulleys, you require a greater amount of rope to achieve the same result. Since you have decreased the effort needed to lift the load you have to apply the force for a longer period of time. Understand the mechanism of the simple machine, the pulley. Understand and learn about how these machines make work a lot more easier and less time consuming with the help of this animated learning module for kids.
