Lesson 3 — 1.2 Balanced forces

Lessonplan
Lesson plan
Opening — 5 min
- Lesson plan
- Goals
- Tug of war — which side applied more force? what effect did that have?

Class phase — 15
- Balanced and unbalanced forces
• Examples — force the students to come up with examples
• Effects — let the students fill in the table of balanced and unbalanced with stationary and moving.

Solo phase — 20 min
- Fill in the table
- Start the homework

Closing — 10 min
- discuss the table
- What have you learned + goals
- Next lesson – homework
Learning goals
• Explain the difference between balanced and unbalanced forces
• Describe the effect of balanced forces
• Describe the effect of unbalanced forces

The forces on an object are 
balanced.
How does this effect its motion when...

  • It is stationary?

  • it is moving at a constant speed?

Slide 23 - Diapositive

Cet élément n'a pas d'instructions

Balanced Forces
When an object is...
  • stationary –> It stays stationary

  • Moving –> travels at a constant speed.

Slide 24 - Diapositive

Cet élément n'a pas d'instructions

The forces on an object are unbalanced.
How does this effect its motion when...

  • it is stationary?

  • it is moving at a constant speed?

Slide 25 - Diapositive

Cet élément n'a pas d'instructions

Unbalanced forces
When an object is...
  • stationary –> It starts moving

  • Moving –> accelerates or decelerates
