Air Resistance and Friction Explained KS3

A comprehensive and enjoyable explanation of the causes and effects of air resistance and friction with animated PowerPoints which:

• demonstrate air resistance as resulting from collisions between the front of an object and air particles;
• demonstrate how friction is caused by collisions between “bumps” in sliding surfaces and slows them down and produces heat;
• demonstrate why streamlined bodies reduce air resistance to travel faster;
• provide a visual explanation of the relationship between acceleration due to gravity, sir resistance, steady speed and why parachutes work.

The three practicals investigate:

• the relationship between the force needed to move a shoe over different types of surface.
• the relationship between surface area of a parachute and air resistance
• do streamlined objects travel faster in water?

What’s Covered

• Friction is a force which opposes motion and is measured in newtons (N).
• Friction increases with the roughness of the surface.
• Friction is caused by collisions between “bumps”, sometimes microscopic, as surfaces slide over each other.
• Collisions slow things down and produce heat.
• How lubricants reduce friction
• Air resistance results from collisions between the front of an object and air particles.
• Steady speed.
• Air resistance wastes energy and slows moving objects

Suggested lesson plan showing choices possible between resources

This pack contains thirty-one resources and it is intended that the teacher uses them to build their own unique lesson to take account of student ability and time available. Literacy, oracy, self-assessment and peer assessment are all built in to the resources. These features are clearly marked on the comprehensive one-page flow chart lesson plan which shows where the logical choices between resources can be made.
