⚙️ Newton's Three Laws of Motion
This quiz explores the fundamental principles of motion and forces that explain how objects move and interact. Test your understanding of inertia, acceleration, and action-reaction pairs. **What you'll learn:** - Explain Newton's First Law and the concept of inertia - Apply Newton's Second Law using force, mass, and acceleration - Identify action-reaction pairs in everyday situations - Predict motion outcomes using Newton's laws - Analyze forces and motion in real-world scenarios

- Question 1
Newton's First Law states that an object at rest will remain at rest unless acted upon by an unbalanced force.
- Question 2
A car maintains a constant speed of 60 km/h on a straight road. What is the net force acting on the car?
- Question 3
Newton's Second Law can be expressed as , where is the net force in Newtons, is mass in kilograms, and is acceleration in ___.
- Question 4
A heavier object requires more force than a lighter object to achieve the same acceleration.
- Question 5
Which pair represents an action-reaction pair according to Newton's Third Law?
- Question 6
If a net force of 20 N is applied to an object with a mass of 4 kg, the acceleration will be ___ m/s².
- Question 7
Arrange these steps in the correct order to analyze a motion problem using Newton's laws.
- Question 8
A cyclist and bicycle have a combined mass of 80 kg. The cyclist applies a force of 160 N to accelerate forward. Assuming negligible friction, what is the acceleration of the cyclist and bicycle system?
- Question 9
When a swimmer pushes backward against the water, the water pushes the swimmer forward with a smaller force because the swimmer is less massive than the water.
- Question 10
Two objects, A and B, experience the same net force. Object A has twice the mass of object B. How does the acceleration of A compare to that of B?
