### 8. Newton's Second Law: Physics Lab

After watching this lesson, you will be able to explain Newton's 2nd Law and use real-life evidence to show that the basic ideas behind the equation are correct. A short quiz will follow.

### 9. The Effect of Friction on Accelerating Objects: Physics Lab

After watching this video, you will be able to explain why friction exists when two surfaces move alongside each other. We'll also conduct investigations to compare the amount of friction created by different materials. A short quiz will follow.

### 10. Newton's Third Law: Physics Lab

After watching this lesson and completing the lab, you will be able to explain what Newton's 3rd Law is, and use an equation to show why two forces can be equal and opposite, and still lead to two objects moving in different ways. A short quiz will follow.

### 11. Conservation of Momentum: Physics Lab

After completing this lab, you will be able to explain what conservation of momentum is and conduct an experiment to demonstrate conservation of momentum. You can also take the short quiz to test your knowledge.

### 12. Energy Conversions Using Inclined Planes: Physics Lab

After completing this lab, you will be able to explain what conservation of energy is and use it to calculate how much energy is lost to friction when an object goes down a ramp. A short quiz will follow.

### 13. Centripetal Motion: Physics Lab

After watching this video, you will be able to explain what centripetal motion is, provide an example of centripetal forces, and use the equation for centripetal force in a real-life scenario to calculate the tension in a string. A short quiz will follow.

### 14. Rotational Inertia: Physics Lab

After completing this lab, you will be able to explain what rotational inertia is and take data to calculate the rotational inertia of a flywheel. A short quiz will follow.

### 15. Universal Gravitation: Physics Lab

Universal gravitation is the link that keeps the universe from falling in on itself. In this lesson, we see how it works and discuss how to use the formula of universal gravitation to find out differing weights.

### 16. Stable Orbital Motion of a Satellite: Physics Lab

In this lab, you're going to learn about satellites in stable orbital motion. You will set up an experiment to simulate the orbit of a satellite and explore the shapes this orbit can take.
