​What is Motion Energy ?

​

Motion Energy is another word for Kinetic Energy.

​

​Motion Energy energy is the energy an object has because of its motion!

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 ​

Multiple Choice

Which ramp height would create the most amount of motion energy for a ball rolling down a ramp?

• One Block

• Two Block

• 3 Block

Open Ended

How do you know an object has motion energy? Explain your thinking in 3-5 sentences.

​

Multiple Choice

Which choice best describes "acceleration"?

• An object speeding up or getting faster.

• When an object is slowing down or getting slower.

• When an object is still or not in motion.

• When an object's speed remains the same

Multiple Choice

How do you test or calculate speed?

• With a Timer

• With a Calculator

• With a Scale

​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.​

​

​

Multiple Choice

Lindsay ran a mile in 7 min and Annabella ran a mile in 8 min who had more motion energy?

• Lindsay

• Annabella

​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.​

​

Multiple Choice

Which ramp height would create the most amount of motion energy for a ball rolling down a ramp?

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

​

​

Multiple Choice

When an object in motion is slowing down...

• the amount of motion energy is increasing or becoming more.

• the amount of motion energy is decreasing or becoming less.

• the amount of motion energy does not change.

Multiple Choice

The smoother the surface, the ____the friction, the _____the object will travel.

• The smoother the surface, the

  less the friction, the

  ​faster

  the object will travel.

• The smoother the surface, the

  more the friction, the

  ​faster

  the object will travel.

• The smoother the surface, the

  less the friction, the

  slower

  the object will travel.

• The smoother the surface, the

  more the friction, the

  slower

  the object will travel.

​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

​

​

​

Multiple Choice

Newton's Cradle is a model that shows....

• how heat energy turns into sound energy.

• howsound energy is changed into motion energy.

• how motion energy moves (or is transfered) from one object to another object.

​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!

Open Ended

Which surface would allow for a ball to roll farther, the smooth surface or the rough surface? Explain your thinking.

​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.

Multiple Select

Energy comes in many forms. Choose ALL the forms of energy from the list below.

• Motion

• Sound

• Heat

• Friction

• Light
