Define Newton’s first law of motion.
- A body will remain/continue in a state of rest or uniform motion/velocity unless acted upon by external (or unbalanced) forces

Apply methods of minimizing and maximizing friction in a sport.
-
Maximize friction:
-
Specialized footwear with grip (spikes/studs/cleats)
1 mark -
Modified playing surface (astroturf/tarmac)
1 mark -
Use of gloves or talc to increase grip
1 mark -
Warming equipment (e.g. squash balls, tyres) OR increasing surface area (e.g. cyclist on velodrome)

Explain how Newton’s laws of motion apply in a team sport.
-
Newton's First Law: Object remains stationary unless external/unbalanced forces applied
1 mark - Example: Goalkeeper standing still before a penalty kick
-
Newton's First Law: Object maintains constant velocity unless external forces act
1 mark - Example: Player running at steady speed during sprint
-
Newton's Second Law: Greater force leads to greater acceleration of performer/equipment
1 mark - Example: Force applied when kicking a football
-
Newton's Third Law: Action-reaction pairs - as athlete pushes down, ground pushes up with equal force
1 mark - Example: Basketball player jumping for a rebound
