Force, Motion, and Energy

Force, Motion, and Energy

By Mrs. Dunson

Kinetic energy is the energy of motion.

​

There is more kinetic at the lowest point.​

Potential energy is energy that is stored.

​

There is more potential at the highest point.​

Calculating Speed

To calculate speed:

​

Speed= Distance/Time​

​

Multiple Choice

A man was training for a marathon. One afternoon he jogged 18 miles in 3 hours. Find the speed by calculating distance divided by time.

• 20 mph

• 15 mph

• 54 mph

• 6 mph

• Transfer of heat through direct touch

​

• Example: Ironing clothes​

​

Conduction

​

• ​Heat circulates through fluids (air or liquids)

​

• Examples: A hot air balloon rising​

​

Convection

​

• Heat is transferred through empty space (no medium) by waves

​

• Example: The sun warming the Earth​

​

Radiation
