Oct 13, 2025 by wbrum.org 98 views

Introduction

In this experiment, we aim to calculate the applied force of washers on a car. To achieve this, we need to convert the mass of the washers from grams to kilograms and then use the formula for force to determine the applied force. This experiment is a great way to apply the principles of physics to real-world scenarios.

Materials

Washers of different sizes
A car or a surface to apply the force
A scale or balance to measure the mass of the washers
A calculator or computer to perform calculations

Procedure

Record the mass of one, two, three, and four washers in grams using a scale or balance.
Convert the mass of each washer from grams to kilograms using the conversion factor 1 kg = 1000 g.
Record the calculations in Table D.

Calculations

To convert the mass of each washer from grams to kilograms, we will use the following formula:

mass (in kg) = mass (in g) / 1000

We will perform this calculation for each washer and record the results in Table D.

Calculations for Each Washer

Washer 1

Mass (in g) = 10.5 g Mass (in kg) = 10.5 g / 1000 = 0.0105 kg

Washer 2

Mass (in g) = 21.0 g Mass (in kg) = 21.0 g / 1000 = 0.0210 kg

Washer 3

Mass (in g) = 32.5 g Mass (in kg) = 32.5 g / 1000 = 0.0325 kg

Washer 4

Mass (in g) = 44.0 g Mass (in kg) = 44.0 g / 1000 = 0.0440 kg

Table D: Mass of Washers in Kilograms (Updated)

Number of Washers	Mass (in g)	Mass (in kg)
1	10.5	0.0105
2	21.0	0.0210
3	32.5	0.0325
4	44.0	0.0440

Calculating the Applied Force

To calculate the applied force, we need to use the formula:

force (in N) = mass (in kg) x acceleration (in m/s^2)

Since we are applying the force to a car, we can assume a constant acceleration of 9.8 m/s^2 (the acceleration due to gravity).

We will calculate the applied force for each washer and record the results in Table E.

Number of Washers	Mass (in kg)	Applied Force (in N)
1	0.0105
2	0.0210
3	0.0325

Calculations for Each Washer

Washer 1

Mass (in kg) = 0.0105 kg Applied Force (in N) = 0.0105 kg x 9.8 m/s^2 = 0.103 N

Washer 2

Mass (in kg) = 0.0210 kg Applied Force (in N) = 0.0210 kg x 9.8 m/s^2 = 0.206 N

Washer 3

Mass (in kg) = 0.0325 kg Applied Force (in N) = 0.0325 kg x 9.8 m/s^2 = 0.319 N

Washer 4

Mass (in kg) = 0.0440 kg Applied Force (in N) = 0.0440 kg x 9.8 m/s^2 = 0.432 N

1	0.0105	0.103
2	0.0210	0.206
3	0.0325	0.319
4	0.0440	0.432

In this experiment, we calculated the applied force of washers on a car by converting the mass of each washer from grams to kilograms and using the formula for force. We recorded the results in Table E and found that the applied force increases with the number of washers.
