9-20 Unit 3 Force of Weight Activity

Last updated almost 3 years ago
25 questions
We Will: investigate the difference between mass and weight as it relates to Newton’s Laws of Motion
I Will: finish Tow Mater and gather data for this activity, finishing it in class today as time allows.

Weight can increase without changing the mass of an object?

1

An objects mass can change without changing the amount of matter in the substance

1

Which of the following apply to the law of conservaiton of matter

1

Weight is...

1

Mass is...

Take a moment to think about your observations of weight you have experienced in the world. The first step of the scientific method is to observe the world around you.
Question for thought: What is the relationship between mass and weight?
2

Hypothesis. Read over your lab procedures for today. Design a testable hypothesis to the question above using an if/then format.

1

When you hook a mass to a spring scale what happens to the spring

1

What does the length of the spring indicate about the mass hanging from it?

1

What is the SI unit for mass?

1

What is the unit for Force?

1

What is the symbol for Force

Procedure: (12 minutes)
Complete the following instructions. Masses can be used individually or combined.
  1. Record the mass on the data table.
  2. Hook the mass or combination of masses onto a red spring scale. Do not exceed 1000g. Record the mass on the google sheet data table.
  3. Read the Force in Newton's side of the spring scale. Record the Force exerted on the spring scale in Newtons in the google sheet data table.
  4. Repeat for a total of 5 different masses
Data Analysis: Using your gathered data, graph the Force acting on the spring scale on the y-axis vs the mass on the x-axis.
Link to google sheet to create your data table and graph.

What units are used for the x axis of the graph?

3

Newtons can also be written as kg m/s2 (see image).

If Newtons are divided by mass (kg), what is the resulting unit.

3

What is the slope of the line graph? use correct units

Match the following

Draggable itemCorresponding Item
Unit of Force
N
Unit of mass

Unit of Acceleration
m/s2
3

If the mass is not moving then the only downward force acting on the mass is

4

based on your data, the acceleration of gravity acting on your mass equals (Hint: You've already calculated this)

3

Can the mass of an object change based on where in the universe the object is located. Why or why not?
