If you roll a bowling ball so it moves faster, what happens when it hits the pins?
A faster ball causes more change to occur than a ball that is moving slowly.
Kinetic Energy and Speed
The faster the ball goes, the more kinetic energy it has. This is true for all moving objects.
The Intimidator at Carowinds starts out with a 232-foot (71 m) lift hill that has a 211-foot (64 m) drop angled at 74 degrees. At the bottom of this drop, the train reaches its top speed of 80 miles per hour (129 km/h) and pulls up into the second, 178-foot (54 m) hill.
The seats of the Intimidator set high on the car. There is no belt or over the shoulder harness. Each seat gives a clear view forward and to the sides. This ride really scared Mr. Bradley.
The potential energy of an object is greater if it is higher above the floor.
Potential energy also depends on mass. The more mass an object has, the more potential energy it has.
Potential energy is the energy associated with an object’s height. When the girl was on the tower she only had a small amount of potential energy. When she jumped off the tower she had a lot more potential energy
A base jumper leaps backwards off the Menara Kuala Lumpur Tower, Malaysia, Wednesday, Oct. 28, 2009. This tower is a 915 feet high communication tower.
Nuclear power plants use the energy stored in the nucleus of an atom to generate electricity.
Every atomic nucleus contains energy— nuclear energy —that can be transformed into other forms of energy.
The thousands of mirrors combine to produce temperatures up to 3,000 °C (5,430 °F). 1,420 flat mirrors automatically track the sun and concentrate the light on a parabolic reflector. The reflector then concentrates the rays to produce 1000 kw energy.
When you buy home solar panels for your own use, government programs entitle buyers of solar panels and other similar devices to tax credits and even rebates.
