Hooke’s law
F = - k x
F – force (N)
k – spring constant (N/m)
x – deformation (m)
Hooke’s law describes an “ideal” spring. It is a good
approximation for real
springs.
What is the meaning of the minus sign in Hooke’s law?
26
The force exerted by the spring is in the opposite direction from the
deformation.
TEST
Answer the following questions, based on your knowledge of Hooke’s law
1) Which the following equations represents Hooke’s law?
a. F=k x
b. F=-k x
c. F=k/x
d. F= -k/x
2)
Which of the following properties reaches a maximum when the
displacement of a spring is at a maximum? Select all that apply.
a. velocity
b. acceleration
c. spring force
d. mass
e. spring constant
3) If a 350g mass hands from a spring with a spring constant of 21 N/m, what
is the displacement of the spring in centimeters?
a. 16.33 cm
b. 0.1633 cm
c. 1.633 cm
d. 1633 cm
4) A spring has a mass of 3.1 kg and hands from a spring with a spring
constant of 3.17 N/m. What is the net force acting on the spring when it
reaches equilibrium?
a. -96.3N
b. 96.3N
c. 0
d. 192.6N
5) The force exerted on a mass handing from a spring is -31N. The
displacement of the spring is x=8.14cm. Calculate the spring constant.
5 Excellent
3-4 Quite good
1-2
This is difficult for you.
