GCSE Springs Core Practical ETE

How do you calculate force (weight) from a mass?

• Mass in grams x 10

• Mass in kilograms x 10

• Mass in grams x 100

• Mass in kilograms x 100

How do you calculate the extension of the spring?

• The stretched length - the unstretched length

• The stretched length + the unstretched length

• The stretched length x the unstretched length

• The stretched length ÷ the unstretched length

What graph should you plot to find the spring constant, k and the energy in the stretched spring?

• Mass on the y-axis and length on the x-axis

• Mass on the y-axis and extension on the x-axis

• Force on the y-axis and length on the x-axis

• Force on the y-axis and extension on the x-axis

How do you use a force-extension graph to find the spring stiffness, k?

• Calculate the gradient

• Calculate the area under the line

How do you use a force-extension graph to calculate the energy stored in a stretched spring?

• Calculate the gradient

• Calculate the area under the line
