Final Review

HOW DO WE KNOW AN OBJECT HAS MOTION ENERGY ?​

​

We know an object has motion energy if it is making sound , light , head or we can observe motion !

​

We know an object has motion energy ​

​

​Runners are try to finish running the race as fast as possible!

​

Runners who run a mile in the LEAST amount of time have more motion energy than runners who take longer to run the same distance.​

​

​

​Height directly effects speed !

​

Increasing the height of a ramp increases the incline of the ramp, which in turn increases the speed at which an object goes down the ramp.​

​

​When an object slows down the motion energy of the object will decrease.

​

​

​Newton's Cradle is a model that shows the conservation of energy and momentum, both of which involve mass.

​

The impact of one ball will move another ball

​

​

​

​The surface that is SMOOTH would allow a ball to roll the furthest because the SMOOTH surface has less friction. 

Surfaces with more friction slow objects down more than smooth surfaces so the rough surface would not allow the ball to roll far!

​FORMS OF ENERGY

​

​

​Energy exists in many different forms, such as heat, light, sound, and movement. It cannot be made or destroyed, just changed from one type of energy to another.
