1. 6th Grade: energy, motion, force, and work
Topic 1 Lesson 1
6th Grade: energy, motion, force, and work

2. Vocab Energy – the ability to do work or cause change
Motion – an object’s position changes relative to another object
Force – a push or pull
Work – when the force exerted is in the same direction as the motion
Power – the rate at which work is done
Maximum – the most or highest point

3. Guiding Questions How is energy related to motion and force?
What are the relationships among energy, motion, force, and work?

4. Energy How does energy relate to motion?
How does energy relate to force?

5. Energy, Motion, Force, and Work
How are these concepts related?

6. Motorcycles (Page 4 & 5)
Answer the questions for the “Connect It!”

7. Motorcycles (Page 4 & 5) Answer the questions for the “Connect It!”
How is the motorcycle using mechanical energy? Chemical, thermal, light, and sound?

8. Work Work (Joule) = Force (Newton) x Distance (Meter)
The unit for Work is a Joule
Joule = Newton x Meter

9. Practice in Notebook! Show your work! Work(J)=Force(N) x Distance(m)
1. How much work is done
by a person who uses a
force of 27.5N to move
a grocery buggy 12.3m?
2. How much work is done by a person who pushes a lawnmower with a force of 50N at a distance of 450m?
3. 55,000J of work is done
to move a rock 25m.
How much force was
applied?

10. Power Power (Watt) = Work (Joule) / Time (Second)
The unit for Power is a Watt
Watt = Joule / Second

11. Model it! Power Work Force Motion Energy needed for motion
Force acting upon an object can change motion
Power
Work
Force
Motion
Energy needed for motion
Energy used to exert force
Power= Energy Transferred/Time
Energy is transferred during work
If work is sdone, there is motion
Power=Force x Distance/Time
ENERGY
Power= Work/Time
