1 Standard I can determine what causes objects to speed up, slow down  or change direction Entry Task Update table of contents Pg. 13 – Explanation Focus Chart Pg. 43 Forces and Energy Turn in notebook rubric Learning Target How do forces relate to energy? At home Complete study guide – test on Wednesday

2 34 35 Modeling Forces: First attempt
Modeling Forces: Final Understanding Redraw your system adding all the forces as it goes down the ram and finally comes to a stop 34 35

3 Modeling Forces: Final Understanding

4 How do forces relate to energy?
Energy – Something stuff has that enables it to do work Work – When a force is applied over a distance Force – A push or pull when two objects interact

5 42 43

6 Forces and Energy… KE KE KE Max GPE 0-KE GPE Forces
-Effort force – TRANSFORMS KE to GPE -Gravity- TRANSFORMS GPE to KE KE GPE - Impact force - TRANSFERS KE to Sand Forces TRANSFER or TRANSFORM Energy - Friction - TRANSFORMS KE to TE (thermal) KE KE

7 TRANSFER or TRANSFORM Energy
Forces and Energy… Forces TRANSFER or TRANSFORM Energy -Effort force- TRANSFORMS KE to GPE The ball will roll until all KE is transformed to TE -Resultant force- TRANSFORMS GPE to KE -Friction- TRANSFORMS KE to TE and SE Give students 2- three minutes to draw car and discuss the forces acting on the car. Have students share their ideas. Then reveal the answer (This still should be review) Motion 0-KE 0- GPE 0-KE 0- GPE Motion

8 TRANSFER or TRANSFORM Energy
Forces and Energy… -Friction- TRANSFORMS KE to TE and SE -Gravity- TRANSFORMS GPE to KE -Forces- TRANSFER or TRANSFORM Energy

9 TRANSFER or TRANSFORM Energy
Forces and Energy… Forces TRANSFER or TRANSFORM Energy -Thrust- TRANSERS KE TO PLANE -Gravity TRANSFORMS GPE TO KE -Thrust- TRANSERS KE TO PLANE And KE to Sound -Lift- TRANSFORMS KE TO GPE -Friction- TRANSFORMS KE to TE
