Parallelogram of Forces Quiz

What is the purpose of constructing a parallelogram of forces?

• To calculate the speed of an object

• To work out the resultant force of two forces

• To measure the distance traveled by an object

• To determine the weight of an object

In the first example, what was the length of the resultant force line in centimeters?

• 10

• 15

• 11.5

• 7.5

What is the scale used to convert centimeters to Newtons in the first example?

• 1 centimeter = 7 Newtons

• 1 centimeter = 2 Newtons

• 1 centimeter = 10 Newtons

• 1 centimeter = 5 Newtons

In the second example, what was the value of the force in Newtons?

• 20

• 13

• 15

• 10

What is the correct process for constructing a parallelogram of forces?

• Shift one line across, shift one line up, connect it, and use the scale to work out the magnitude

• Shift one line down, shift one line across, and measure the length of the line

• Connect both ends of the diagrams, drop a line between them, and measure the length

• Shift one line up, shift one line across, and draw a line between them
