Newton's Laws Investigation
🔬 Part 1: Understanding Newton's Laws
1. Newton's First Law states that an object at rest will stay at rest unless acted upon by:
Gravity
An unbalanced force
Friction
Its own weight
2. Which equation represents Newton's Second Law?
F = ma
F = m + a
F = m ÷ a
F = a - m
3. Newton's Third Law can be summarized as:
Objects in motion stay in motion
Force equals mass times acceleration
For every action, there is an equal and opposite reaction
Friction always opposes motion
4. Which of the following are examples of forces? (Check all that apply)
Pushing a shopping cart
Gravity pulling an apple down
Wind blowing leaves
The color red
📊 Part 2: Applying the Laws
5. A 10 kg object is pushed with a force of 20 N. What is its acceleration? Show your work:
6. Explain why you feel pushed back into your seat when a car accelerates forward. Which of Newton's laws does this demonstrate?
7. A hockey puck slides across the ice and eventually stops. Fill in the blanks:
The puck stops because of _____________ acting against its motion. This demonstrates Newton's _____________ Law because the puck was acted upon by an _____________ force.
8. Draw a free-body diagram showing the forces acting on a book sitting on a table:
🚀 Part 3: Real-World Connections
9. When you walk, you push backward on the ground with your foot. Explain what happens next using Newton's Third Law:
10. Design a simple experiment to test Newton's First Law using everyday materials. Describe your setup and what you would observe:
11. Choose ONE of Newton's Laws and explain how it applies to your favorite sport or activity:
