Friction Experiments and Forces

The video tutorial covers three friction experiments. In the first experiment, a 93.2g cart is subjected to a maximum 2 Newton force using a spring scale. The second experiment repeats the first but with the cart's mass increased to 187.1g. The third experiment involves applying a vertical force to the original 93.2g cart. Each experiment is followed by questions that require analysis using Newton's laws.

What is the maximum force applied by the spring scale in Friction Experiment 1?

• 2 newtons

• 1 newton

• 4 newtons

• 3 newtons

In Friction Experiment 1, what is the mass of the cart?

• 50.0 grams

• 187.1 grams

• 93.2 grams

• 120.5 grams

How does Friction Experiment 2 differ from Experiment 1?

• The surface is changed

• The spring scale is replaced

• The force applied is different

• The cart's mass is increased

What is the mass of the cart in Friction Experiment 2?

• 93.2 grams

• 200.0 grams

• 150.0 grams

• 187.1 grams

In Friction Experiment 3, what type of force is applied to the cart?

• Diagonal force

• Vertical force

• No force

• Horizontal force

Which experiment uses a vertical force applied by the instructor?

• Experiment 1

• None of the experiments

• Experiment 2

• Experiment 3

What remains constant between Friction Experiment 1 and Experiment 3?

• The type of force applied

• The mass of the cart

• The surface material

• The spring scale used
