Assignment 2 Analysis of Effects on Friction

In this assignment, carry out an investigation into the factors affecting static and kinetic friction. You will collect data using the Physics Aviary simulation and then use that data to record observations and answer the following analysis questions. Use the website below for the simulation https://www.thephysicsaviary.com/Physics/Programs/Labs/ForceFriction/index.html

.

Purpose: To analyze the effects of surface area, mass, and material on the force of friction

Hypothesis: (fill this in and include embedded citations)

( Put together an hypothesis based on your own research into how different masses with the same material affect friction).

Procedure: Follow the instructions as you progress through the virtual lab. Record the data in the table below.

Observations: Data table (complete the experiment with 4 different masses in approximately even intervals).

Material/Object characteristics	Mass (kg)	Normal Force (N)	Force of Static Friction (N)	Force of Kinetic Friction (N)	Coefficient of Kinetic Friction (rounded to two decimal places)	Coefficient of Static Friction (rounded to two decimal places)

Sample Calculations: (show all calculations for one entire row) (2 marks)

Graph: Copy and paste or snip one graph below. Write 3-4 sentences explaining what the graph is showing.

Diagrams: Draw free body diagrams to show the forces acting on one concrete block for the following scenarios: (4)

Not moving and not being pulled by the spring.

Not moving and being pulled by the spring and static friction was at its maximum.

Accelerating and being pulled by a force larger than the force required to move it in uniform motion.

Being pulled by a sufficient force to maintain uniform motion.

All forces require labels and appropriate values in Newtons.
