Use the force-versus-extension graph. What is the spring constant of the spring?
The graph shows force on the vertical axis and extension on the horizontal axis. What is the spring constant?
A spring is tested, and its force-extension data are graphed. Which value gives the spring constant?
Use the straight-line graph of force versus extension. What is k for this spring?
The graph shows a spring's restoring force magnitude for different extensions. What is the spring constant?
Use the table of force and extension measurements. What is the spring constant in newtons per meter?
Use the measured data in the table. What spring constant do the data show?
The table gives force and extension for a spring. What is the spring constant?
A spring with k = 250 N/m is stretched 0.12 m from its natural length. What is the magnitude of the restoring force?
A 120 N/m spring pulls back with a force of 18 N. How far is it stretched from equilibrium?
A force of 24 N stretches a spring by 6.0 cm. What is the spring constant?
A spring with k = 75 N/m is compressed 0.080 m. What is the magnitude of the force it exerts?
A 0.50 kg mass hangs at rest from a vertical spring with k = 196 N/m. Use g = 9.8 m/s². How much does the spring stretch?
A spring's extension increases from 0.040 m to 0.070 m. If k = 180 N/m, by how much does the restoring force magnitude increase?
Take right as positive. A spring attached to a cart is stretched 0.050 m to the right from equilibrium, and k = 320 N/m. What is the restoring force component?
A cart attached to a horizontal spring is pulled to the right and released. Before it reaches equilibrium, which way does the spring force act?
In the equation F = -kx for a spring, what does the minus sign mean?
A force-extension graph is straight at first but curves for larger extensions. What does that show?
A spring is still below its elastic limit. If the applied force is doubled from 4 N to 8 N, what happens to the extension?
Two springs support the same 5.0 N load. Spring A stretches 0.020 m, and spring B stretches 0.050 m. Which spring has the larger spring constant?
