⚖️ Part 1: Newton's Laws - Multiple Choice

1. Newton's First Law states that an object will remain at rest or in uniform motion unless:

It gets tired

Acted upon by an external force

It reaches maximum speed

Time runs out

2. Which equation represents Newton's Second Law?

F = m + a

F = ma

F = m ÷ a

F = a - m

3. Newton's Third Law is often summarised as:

Objects in motion stay in motion

Force equals mass times acceleration

For every action, there is an equal and opposite reaction

Energy cannot be created or destroyed

🧮 Part 2: Force Calculations

4. Calculate the force needed to accelerate a 5 kg toy car at 2 m/s². Show your working.

5. A 10 kg object experiences a force of 50 N. Calculate its acceleration.

6. What mass would need a force of 100 N to accelerate at 4 m/s²?

🌍 Part 3: Real-World Applications

7. Which of the following are examples of Newton's Third Law? (Check all that apply)

Walking on the ground

A rocket launching into space

Swimming in a pool

A ball rolling down a hill

Pushing against a wall

8. Explain why a passenger in a car moves forward when the car suddenly stops. Use Newton's First Law in your answer.

9. Draw a diagram showing the forces acting on a toy car being pushed across a table. Label the forces.

🚀 Part 4: Space and Motion

10. Fill in the blanks about rocket motion:

When a rocket launches, hot gases are expelled _____________ from the rocket engines. According to Newton's _____________ Law, this creates an equal and opposite force that pushes the rocket _____________. The greater the _____________ of gas expelled, the greater the force pushing the rocket upward.

11. Match Newton's Laws with their descriptions:

1. First Law

2. Second Law

3. Third Law

A. F = ma

B. Action and reaction

C. Law of inertia
