⚙️ Forces and Newton's Three Laws
This quiz explores Newton's three laws of motion and how forces affect objects in everyday situations. **What you'll learn:** - State and apply Newton's first law of motion - Understand how mass and acceleration relate through Newton's second law - Recognise action–reaction pairs in Newton's third law - Calculate force using $F = ma$ - Analyse forces in practical scenarios

- Question 5
When you push a wall, the wall pushes back on you with a force equal in magnitude but opposite in direction, according to Newton's third law.
- Question 6
A car of mass 1000 kg accelerates from rest to 20 m/s in 10 seconds on a straight road, with negligible friction. What is the net force acting on the car?
- Question 7
When a person jumps, they push downward on the ground with a force, and by Newton's third law, the ground pushes upward on the person with an ___ force.
- Question 8
A net force of zero acting on an object means the object is definitely stationary.
