1.1 Introduction to forces

# Video Resource FanBike.mp4

What is a force?

# Practical

Demo :

• White boards
• Rope (for tug of war)

Round robin -

• Magnet and tied down paperclip
• something floating
• Mass on a string
• Heavy mass on a table

Experiment

• 15x Newton meters mixed 10N nd 100N

Students wander around identifying the force pairs - naming them. They then draw a force diagram

Risk assessment:

• No risk

Risk assessment:

• None- but keep an eye on heavy mass and pupils

# Target:

• Identify some forces acting on objects in everyday situations

• Identify an interaction pair

• Use a newtonmeter to make predictions about sizes of forces

• Explain what forces do

• Describe what is meant by an interaction pair

• Make predictions about forces in familiar situations

• Explain the differences between contact and non-contact forces

• Explain which pairs of forces are acting on an object

• Make predictions about pairs of forces acting in unfamiliar

situations
