A 0.5 kg mass bounces on a spring with a spring constant of 20 N/m. What is its period, to the nearest hundredth, Ari?
A 2 kg mass bounces on a spring with a spring constant of 50 N/m. What is its period, to the nearest hundredth, Bo?
A 0.2 kg mass bounces on a spring with a spring constant of 80 N/m. What is its period, to the nearest hundredth, Esme?
4.
A pendulum timer must have a period of 1 s. With g = 9.8 m/s², about how long must its string be, Jun?
- About 1.56 m
- About 0.25 m
- About 1 m
5.
A mass bounces on a spring with a 1 s period. What spring keeps the mass but halves the period, Luz?
- One with half the spring constant
- One with twice the spring constant
- One with 4 times the spring constant
6.
Noah says a heavier mass on the same spring bounces more slowly. Agree or disagree?
- Disagree: mass can't change a period
- Agree: T = 2π√(m ÷ k)
- Disagree: heavier masses bounce faster
7.
Pia says pulling a pendulum bob back a little farther (still a small swing) changes its period a lot. Agree or disagree?
- Disagree: small swings keep the same period
- Agree: a bigger swing is much quicker
- Agree: a bigger swing takes much longer to complete
8.
A pendulum is taken from Earth (g = 9.8 m/s²) to the Moon (g = 1.62 m/s²). What happens to its period, Ren?
- It gets about 6 times longer
- It stays the same
- It gets about 2.46 times longer
9.
A mass on a spring is taken from Earth to the Moon. What happens to its bounce period, Tala?
- It gets longer, like a pendulum's
- It gets shorter
- It stays the same
10.
Which timer would keep the same time on Earth and on the Moon, Zee?
- A bob on a string
- A mass bouncing on a spring
- Neither of them

About this worksheet

Springs and pendulums. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can use Hooke's law, F = kx (x in meters), and read k as the slope of a force-extension graph.
I can find a pendulum's period, T = 2π√(L ÷ g) with g = 9.8 m/s², and a spring-mass period, T = 2π√(m ÷ k).
I can read a displacement-time trace for amplitude, period and fastest points. I can track potential and kinetic energy in the swing, and predict both timers on the Moon.

Standard: none (TX)

Words to know

spring constant (k): How stiff a spring is, in newtons per meter

period (T): The time for one full swing or bounce

amplitude: The biggest distance from the middle position

pendulum bob: The weight at the end of a pendulum's string

small swing: A swing of a few degrees, where the period formula holds

Common mistakes

Your child used centimeters. The spring constant is in N/m, so change centimeters to meters first.

Your child left out the square root. A pendulum's period is 2π√(L ÷ g).

Your child put k on top. A spring's period is 2π√(m ÷ k): more mass, slower bounce.

Questions parents ask

What is the most common mistake with springs and pendulums?

Your child used centimeters. The spring constant is in N/m, so change centimeters to meters first.
